Maintenance for High Mileage Vehicles In Phoenix Arizona

Posted on December 29, 2010 by tireaz

Before the recession hit, the median age for cars in the Phoenix Arizona area (zip code: 85032) was over nine years. And two-thirds had over 75,000 miles. At Community Tire and Automotive Service Specialists we hear reports that those numbers continue to rise.

If you have a high-mileage vehicle in the Phoenix area, bring it in for high-mileage maintenance:

Many people in Phoenix are keeping their vehicles longer. The economy has influenced that, but the fact that modern sedans are more durable and reliable means that owning a high mileage vehicle doesn’t have to be a painful experience.

Local car owners in Phoenix with over 100,000 miles on their vehicles often ask which service intervals they should follow. Let’s start with the special needs of the older vehicle…

The reality is that time and mileage will take its toll. The engine and transmission will have more sludge. The fuel, steering and brake systems will have gum and varnish built up. There’ll be more dirt and contaminants in the fuel tank. Corrosion and deposits in the cooling system. And seals and gaskets will start to dry out.

All of this, plus normal wear and tear, means that the engine might not be as strong as new, so it just has to work harder to get the job done.

So we need to compensate. Consider high-mileage formulations for oil changes, transmission service, etc. These special formulations contain additives that condition the seals and gaskets to prevent leaks. They also have more detergents to clean sludge and other deposits. They cost a bit more, but they’re worth it.

In general, if an auto service was recommended every 15,000 miles when the car was new, you should continue to get the service done every 15,000 miles.

Talk with your Phoenix service advisor at Community Tire and Automotive Service Specialists about the condition of your engine. See if he thinks you should adjust your auto service intervals for oil changes or other auto maintenance to account for the older engine working harder.

Expect the oil filter to get dirty faster. Same goes for the fuel filter. And some leaks are to be expected so you need to keep a closer eye on fluid levels.

If anything, following recommended service intervals for your sedan is more important in a higher mileage vehicle. Skipping oil changes or other services can lead to problems much more quickly than with a newer vehicle.

So, have your Phoenix auto service advisor at Community Tire and Automotive Service Specialists help you with an assessment of your older car or truck. If you haven’t gotten around to a fuel system cleaning, or replacing power steering or brake fluid, a differential service or transmission service – it’s time to start taking care of those things. It’ll help keep you on the road for many more happy miles.

Busting Automotive Myths In Phoenix Arizona

Posted on December 24, 2010 by tireaz

Myths passed around our Phoenix Arizona 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 Phoenix area, come over to Community Tire and Automotive Service Specialists.
You’ll find us at 15812 North 32nd Street, Phoenix, Arizona 85032.
Give us a call at 602.992.2830 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 Phoenix. A grease fitting may have been installed in conjunction with a repair. And most trucks and truck-based SUVs driving in Phoenix 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 Phoenix 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. Community Tire and Automotive Service Specialists 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 Community Tire and Automotive Service Specialists 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 Phoenix 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 Community Tire and Automotive Service Specialists have always adapted to keep pace with automotive technology. Next time you come across an angry voice about your car care, talk to your Phoenix service advisor at Community Tire and Automotive Service Specialists, or do some research of your own.

Using Proper Fluids In Your sedan Or Other Vehicle

Posted on December 17, 2010 by tireaz

Today Community Tire and Automotive Service Specialists 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 Arizona 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 Community Tire and Automotive Service Specialists. You can find us on 15812 North 32nd Street in Phoenix, Arizona 85032.
Just give us a call at 602.992.2830

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 Phoenix Arizona 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 Phoenix Arizona service advisor at Community Tire and Automotive Service Specialists 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.

Timing Belt Service to Save Big Bucks in Phoenix

Posted on December 9, 2010 by tireaz

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine, has to do with the combustion cycle.

Your sedan engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call Community Tire and Automotive Service Specialists at 602.992.2830 for answers about your timing belt, or drop by our Phoenix Arizona service center on 15812 North 32nd Street, 85032

It’s critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It’s vital and precision work. Timing belts are made of very tough flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bend or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It’s a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it’s at 60,000 miles. For others it’s at 90,000 miles or more. If you’re approaching 60,000 miles, or have passed it, make sure you check your owner’s manual or with your Phoenix Arizona auto service advisor at Community Tire and Automotive Service Specialists for when the timing belt should be replaced. Don’t let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Community Tire and Automotive Service Specialists for an inspection right away if you have a coolant leak.

Most people in the Phoenix area with this engine design end up with a new timing belt when they replace the water pump. And when you’re having your timing belt replaced on schedule, check with your Phoenix Arizona auto service advisor at Community Tire and Automotive Service Specialists to see if it makes sense to install a new water pump, even if it isn’t currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don’t need to be replaced like belts.

We’ve already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Community Tire and Automotive Service Specialists in Phoenix Arizona so you can begin to prepare for the expense.

Keep it Flowing With A Fuel Filter Replacement At Community Tire and Automotive Service Specialists

Posted on December 2, 2010 by tireaz

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Phoenix Arizona use fuel filters.

For more information about your fuel filter, visit Community Tire and Automotive Service Specialists or come by our shop located at 15812 North 32nd Street in Phoenix, Arizona 85032.
Please call 602.992.2830 to make an appointment.

Generally speaking there’s not a lot of dirt in our Phoenix Arizona auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That’s because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your sedan is five years or older, it can actually have a fair amount of sediment built up.

That just means that the fuel filter has to work harder as your sedan ages. It’ll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars of repair bills.

Those auto service schedules in your owner’s manual are there for a reason. If ever you don’t understand a recommended service, just ask your Phoenix service advisor at Community Tire and Automotive Service Specialists. We’ll be happy to explain.
