Busting Automotive Myths In Martinez CA

Posted February 21, 2012 9:45 AM

Myths passed around our Martinez CA community start with a grain of evidence and are then built up with a lot of imagination and very elastic logic. And the internet is a breeding ground for automotive myths. Some bloggers recall the sedans of yesteryear and declare their modern decedents to be virtually maintenance free and that anyone who says otherwise is out to rip you off.

To get the truth about auto myths you hear around the Martinez area, come over to Hagin's Automotive.
You'll find us at 3725 Alhambra Avenue, Martinez, CA 94553.
Give us a call at 9252285115 to make an appointment for your next auto service.

Let's examine a couple of the more popular rants and look at the truth behind them.

The first one is that the chassis no longer needs lubrication for suspension, steering and the driveline. They declare that anyone who has charged you for lubrication is a charlatan.

The truth on which this myth is based is that many new cars come from the factory with sealed joints and cannot be greased. However, there are still some grease points on many cars around Martinez. A grease fitting may have been installed in conjunction with a repair. And most trucks and truck-based SUVs driving in Martinez still require chassis lubrication. This is because they are more heavy duty and proper greasing is still required to keep them going.

Another common rant you'll hear around Martinez is that modern cars don't need tune-ups. That depends on your definition of a 'tune-up', which has changed as technology has progressed. Before engine control computers, electronic ignition and fuel injection, a tune up meant replacing mechanical parts that wore out. Hagin's Automotive would manually adjust fuel and air mix and timing. When these adjustments were off, spark plugs would foul and need to be replaced.

This definition just doesn't apply to modern vehicles. Service centers like Hagin's Automotive generally consider a tune-up to be the major service visit, recommended by your manufacturer, every 30,000 miles or so.

Of course you can't lubricate a sealed joint. Of course you can't adjust a carburetor if your car doesn't have one. You probably don't need to change spark plugs every year if your manufacturer says they can go 30,000 miles. What are these bloggers getting so worked up about?

The danger with these modern-day myths, is that they prevent people in our local Martinez community from taking care of the routine preventive auto maintenance that manufactures recommend. Check out this partial list of things you still need to do to take care of your car. How many of them are really any different today than they were 20 or 30 years ago?

Oil change, cooling system service, transmission service, tire balancing, tire rotation, wheel alignment, suspension service, power steering service, proper tire inflation, brake service, differential service, battery maintenance, engine air filer, PCV valve, breather element, fuel filter, belts, hoses, timing belt, windshield wipers . . .

You get the picture. Your sedan is still a machine that needs to be maintained. And, hey, your service advisors at Hagin's Automotive have always adapted to keep pace with automotive technology. Next time you come across an angry voice about your car care, talk to your Martinez service advisor at Hagin's Automotive, or do some research of your own.

Using Proper Fluids In Your sedan Or Other Vehicle

Posted February 15, 2012 10:35 AM

Today Hagin's Automotive is talking about the proper fluids for your vehicle. It's become more complicated with changes in automotive design and manufacturing. It's not that people in CA are confused as much as they don't realize how much things have changed in recent years.

If you have questions about the fluids in your vehicle, please don't hesitate to stop by Hagin's Automotive. You can find us on 3725 Alhambra Avenue in Martinez, CA 94553.
Just give us a call at 9252285115

Let's take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it's cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn't thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the car has been turned off for a while, the oil tends to run down to lower areas and the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It's certainly in the owner's manual. Of course, your Martinez CA auto service center can look it up for you.

It's more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn't formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you're using the wrong coolant, your cooling system won't be covered under warrantee. So it's important to use the right coolant and to not mix different types.

Your owner's manual or your Martinez CA service advisor at Hagin's Automotive can make sure you're using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That's OK for an emergency top off, but following your manufacturer's recommendation for your sedan or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It's important to remember that the new ones aren't better than the old ones. They're just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid, and so on that contain additives to condition and restore seals and gaskets in older engines.

They're fine to use as long as they're a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it's also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it's the right type for your transmission.

Power Steering: Keep Headed in the Right Direction, Martinez

Posted February 8, 2012 10:20 AM

Power steering is standard on nearly every car and truck in Martinez, CA these days. Now there are some exotic, new types of power steering systems, but for the most part, the heart of the system is a pump that’s driven by a belt powered by the engine.

Contact us at Hagin's Automotive for questions about your power steering.

The pump generates boost that assists you as you steer your sedan around Martinez, CA. Power steering systems use hoses to move pressurized fluid back and forth. These hoses can develop leaks so it’s a good idea to inspect them at every oil change.

A check of the power steering fluid level is on the list for every full service oil change because low fluid can damage the power steering pump. And the fluid needs to be compatible with the hoses and seals, so you need to use the correct type –just ask your service consultant at Hagin's Automotive.

In addition to providing boost, the fluid cleans, cools and lubricates the power steering system. The lubricants and detergents are depleted over time so you need to replace your old fluid with clean, fresh fluid periodically.

Excess moisture can collect in the power steering fluid as well. That can lead to rust and corrosion as well as reduce the effectiveness of the fluid. Many manufacturers specify power steering service intervals in the owner’s manual. Unfortunately, this important service is sometimes left off the maintenance schedule. When in doubt, every two years is a good fallback.

Your auto service center in Martinez, CA will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Now, if you are experiencing high steering effort, erratic power assist, loud whining coming from the pump you may have a power steering problem. Another sign is that you have to frequently top off the fluid.

Holding the steering wheel to the far right or left for more than a few seconds at a time can wear your pump out real fast. AutoNetTV wants you to be sure to service your power steering system regularly to keep you headed in the right direction.

Custom Wheels and Tires For Your Martinez Ride

Posted February 1, 2012 10:40 AM

It seems like everywhere you go in the Walnut Creek area you see custom wheels. Big trucks, little cars, mini-vans - it doesn't matter, people are expressing themselves with custom wheels. Some people want smaller tires and wheels - some want larger - and some want them enormous. So where do you start if you want new wheels? We suggest you start with your budget. We know, that sounds so practical. But if the look you're after goes beyond just new tires and wheels and enters into the world of suspension modifications, you need to be prepared for the additional cost.

Let's start with something easy - you want to give your ride a unique look and the stock wheel size is just right for you. One of the concerns you will have is that the new wheels have the same offset as your factory wheels.

First, what is offset? The wheel bolts onto the hub on the car's axle. The distance from the inside edge of the wheel to the point at which it bolts on, is the offset. If the new wheel has a different offset from the factory, the tires may rub on the inside or outside of the wheel well. That could lead to catastrophic tire failure.

Your tire and wheel professional at Hagin's Automotive can help you find the right size wheel - or install adapters to make your new wheels fit. All you have to do is pick from the hundreds of styles available.

So, what if you want to upsize? Well, if it is just bigger wheels you want, but you want to keep the same overall tire diameter, that's pretty easy. The same offset concerns apply. You need to know that the tires will likely be a little bit wider than the originals and could rub when you make sharp turns. Your tire professional at Hagin's Automotive will help you avoid this.

It is also important to keep the same overall tire diameter because changing the rolling diameter can mess with your anti-lock brakes and stability control systems. Are you starting to see why you want to consult with a tire and wheel expert at Hagin's Automotive? Is "super-size me" your motto? If it is, you are going to have to lift your vehicle to make room for those huge tires. A mild lift doesn't require extensive modifications. An extreme lift means a lot of new hardware under the vehicle. It also means a lot of stock electronic systems need to be recalibrated to the new tire size. For example, your speedometer and odometer will give false readings if they aren't recalibrated.

You should also be aware of possible performance issues. Bigger tires and wheels weigh more. Experts refer to this as unsprung weight because it isn't held up by your suspension system. Increased unsprung weight affects performance in different ways than an equivalent amount of groceries or little soccer players in the passenger compartment. Acceleration is negatively affected. Stopping distances may also be increased - sometimes dramatically. If you want really big tires and wheels, you might need to upgrade your brakes to compensate.

Heading the other direction, some folks like to run smaller than standard wheels and lower the suspension. All of the same fitment issues still apply as well as calibration issues. Don't think that suspension modifications are a bad thing. Many systems actually improve ride, function and performance over the stock set-up.

Regardless of your budget, you want your vehicle to continue to do all the things you need it to do. Some of those show cars and trucks you see on TV look fantastic, but have been modified in ways that may not suit your needs. For example, if you put large rims on your SUV with low profile tires, you may be in for busted rims if you go off-roading a lot. There just isn't enough sidewall to absorb the impact of thumping over rocks.

Some people stuff the largest tires and wheels possible in their vehicles but have to severely restrict suspension travel so that the tires aren't rubbing all day. That can lead to a very harsh ride. Again, talk with your wheel professional about all of these things: how you drive, what look you are going for, your budget and what compromises you are willing to make.

At the end of the day, you're going to be rollin' out of there with one sweet ride.

Fuel Saving Tip: Check Engine Light

Posted January 24, 2012 1:32 PM

A question for our Martinez CA motorists: How long have you been enjoying the romantic glow of your check engine light?

Hey, it's not there to create ambiance; it's a warning that something's wrong. When your check engine light comes on get it checked at a capable Martinez CA service station.

Many conditions that cause the check engine light to come on affect fuel economy. Some very dramatically.

Always make sure you tighten your gas cap until it clicks. A loose gas cap can cause a false sensor reading that'll make the check engine light come on.

If your date's eyes are smoldering in the reflected glow of the check engine light, try to think of all the gas money you'll save by getting it fixed. Give us a call when you are ready: 9252285115

Make Your Vehicle Last

Posted January 19, 2012 1:43 PM

We live in such a disposable society. It's amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough - they had to do without. Most people couldn't afford new cars very often, so they had to make them last as long as they could.

It's a good thing that cars are more reliable these days. They just don't break down as often. And the good news for us CA penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us Martinez car owners making sure we follow the manufacturer's recommended maintenance schedules.

Every time you go a couple thousand extra miles between an oil change, you have created an opportunity for sludge to be formed and clog passages. Then some parts don't get properly lubricated and they start to wear out faster. Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged - one step closer to a failure. Same thing is true for transmission service, power brakes, fuel system cleaning - really everything on your schedule.

It is probably even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they are a bit more stressed anyway. But it is never too late to get back on track with your maintenance and to hold off further damage.

And it really does start with the oil change. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. It's like your safety net. Go in for an oil change on time, and let your service advisor help you keep track of the rest.

Some things are going to wear out along the way, things like alternators, water pumps, etc. But fixing those at Hagin's Automotive is cheaper than a new car payment. And taking care of problems early means they have less time to mess with other things. It is like having high cholesterol - you don't want to wait for a heart attack before you address it.

Hagin's Automotive Radiator Service

Posted January 13, 2012 8:11 AM

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common, it is easy to prevent.

Hagin's Automotive

Martinez, CA 94553

The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then goes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it's back to the engine again.

There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.

Another very important coolant issue that is often overlooked is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can't protect the radiator and other parts from rust, scaling and corrosion. Old coolant may still keep your engine cool, but it won't protect it from corrosion.

If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It's OK to add water or antifreeze yourself. But you need to be cautious. Remember four things.

• First, you never want to open the radiator pressure cap. You could be severely burned.
• Second, try to get to your Martinez service center at Hagin's Automotive immediately if your coolant is low. If that is not possible, follow the directions in your owners manual - it will direct you to only make additions to the coolant overflow bottle.
• Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Hagin's Automotive service center where we can make necessary corrections.
• Fourth, not all cars use the same type of antifreeze. You need to check your owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to rely on your Hagin's Automotive service center in Martinez to do things right.

Remember, your Martinez service center has the equipment to change your coolant quickly and inexpensively.

PCV Valve Replacement

Posted January 13, 2012 8:10 AM

The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Gasoline engines used to simply have a hose that let the poisonous fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. Diesel engines are not required to have these valves.

The positive crankcase ventilation, or PCV, valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It's really a pretty simple system, but does an important job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil, but the engine as well. The PCV relieves pressure in the crankcase, preventing oil leaks.

Eventually, the PCV valve can get gummed up. Then it can not move enough air through the engine to keep it working efficiently. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation or surging or an oil leak, it may be a sign of PCV value problems. Your owners' manual may give a recommendation for when the PCV valve should be replaced - usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some manufacturers don't list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed with a visual inspection. Fortunately, PCV valve replacement is both quick and inexpensive. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your Martinez service technician tells you its time to replace your PCV valve, you will know what he's talking about. If you have had your car for a while and this is the first you've ever heard of a PCV value, ask your tech to check yours out or call Hagin's Automotive at 9252285115.

Power Steering Service Near Walnut Creek

Posted January 13, 2012 8:07 AM

For most of us living in the Walnut Creek area, it is hard to remember life without power steering - cranking those great big steering wheels? It was a pretty good workout. Now power steering is standard. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine - a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea to inspect them at every oil change. Low fluid can damage the power steering pump. That is why fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owners' manual for the right type - or just ask your service technician at Hagin's Automotive.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so it needs to be replaced from time to time. Many manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the maintenance schedule for many of us in Walnut Creek. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your Hagin's Automotive service center in Walnut Creek will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some warning signs of trouble with your power steering: It's harder to turn the wheel, there's erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump real fast.

Other steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at Hagin's Automotive will reveal bent or damaged steering components.

Most SUV's, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. It's also recommend the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners' manual maintenance schedule. It's usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Walnut Creek area, the bearings will need service more often.

Trip Inspection

Posted January 13, 2012 8:03 AM

North Americans love their cars. And nothing goes with cars better than the road trip. Freedom from daily schedules, new sights and the open road – it’s great! But there’s nothing like car trouble to bring the fun to a grinding halt.

Now you can’t always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle’s perspective. What kind of roads will you be traveling – winding byways or super-highways? Mountains or plains? What weather conditions are you likely to encounter? How many miles will you travel? How much weight will you be hauling – passengers and luggage? Lugging a trailer or roof top carrier? Will it be dusty?

Armed with the answers to these questions, you can start a trip inspection to help you prepare your Martinez vehicle for your big adventure. A lot of our Martinez customers prefer to go through this exercise with an automotive service advisor at Hagin's Automotive to get their input and make sure they haven’t left anything out.

A great place to start is with the tires. Inspect them for tread wear and proper inflation. Is it time to rotate your tires? Replace them? Are they up to the job – you wouldn’t want to drive regular highway tires on a muddy off-road adventure.

Shocks and struts play a major role in both driving comfort and safety. If they need to be replaced, you’ll really be glad you did once you hit the road. Is it time for a wheel alignment? Fighting a car that’s pulling to one side all day can be tiring and dangerous.

And don’t forget your brakes. Any strange noises, grabbing, soft or hard peddle feel? If there is any doubt, get a brake inspection before you leave.

Moving under the hood, have your belts and hoses inspected. If something is excessively worn or near failure, the stress of a long road trip might just be the straw that breaks the camel’s back.

Your engine air filter will be important. For every gallon of gas you burn, your car will filter and use 12,000 gallons of air. If the filter needs to be changed, you’ll notice the fuel savings on your trip.

How close are you to your next oil change? Will you be able to complete your trip before it’s due? If not, just get it taken care of before you go so that you don’t need to interrupt your trip. In fact, a full service oil change is a great idea because they will top off all your fluids and check to see if any other maintenance items are due, such as transmission or cooling system service.

Do you notice any unusual odors in your vehicle? If so, it could as harmless as a dirty cabin air filter. But if it’s an exhaust leak it could be fatal on a long trip. Of course you’ll want to be comfortable, so get an air conditioning service if you aren’t getting the cold air you used to.

Are you wiper blades still working well? If not, that is quick and inexpensive to fix. Headlamps are often overlooked when planning for a trip. If you haven’t changed the bulb in six months or so, replacement bulbs will really light up the night on your trip.

All the items mentioned are part of any good vehicle maintenance plan. These are things that you want to take care of anyway, but they all come into focus as you plan for your trip.

They will always save you money in the long run and may prevent inconvenient delays on your trip. After all, you wouldn’t want to miss the world’s largest ball of string, would you?
