Then they find themselves in a driving situation around AZ when they really need forward visibility only to discover that their wipers are worn or maybe even torn and can’t clear snow or rain from the windshield.

As an important safety system, wiper blades should be replaced BEFORE they fail. Test your wipers at least once a month. If they are not doing the job, your friendly and professional Arizona Auto and Radiator Repair service advisor can replace them for you.

Diagnosing Your Vehicle at Arizona Auto and Radiator Repair in Sierra Vista

When we Sierra Vista residents get a car repair bill, we really shouldn't be surprised to find “diagnostic fees” as one of the line items. When we get a computer fixed, there is usually a charge for the time it takes to diagnose the problem. When we go to a medical doctor, most of his fee is for his ability to diagnose what's wrong. It's no different with our vehicles.

Some diagnoses are fairly simple. Brake repairs at Arizona Auto and Radiator Repair usually require only a visual inspection, for instance. But other problems are much more difficult to diagnose. An intermittent engine problem, for example, takes time and expertise to pinpoint.

Modern vehicles have multiple computers that monitor a variety of sensors throughout the vehicle. When one of those sensors has a reading that is higher or lower than the standard parameters, the computer turns on the Check Engine light. Technicians at a service center such as Arizona Auto and Radiator Repair in Sierra Vista can scan the engine's computer for a trouble code. This code tells the technician which reading is too high or too low.

That's where some Sierra Vista residents get confused. They think that this reading concludes the diagnosis, and they don't understand why the diagnostic fee is as much as it is when all the technician did was to scan the computer. But the truth is the trouble code is only the beginning of the diagnostic procedure.

Remember, the trouble code only tells which reading is out of parameter. It doesn't say what is causing the reading to be too high or too low. Your Arizona Auto and Radiator Repair service technician still has to find the underlying problem. It's a lot like going to the doctor. He can take your temperature and discover that you have a fever, but that doesn't tell him what is causing your fever.

Automotive diagnostic technology can cut down the time it takes to figure out what's wrong with a vehicle that isn't running right. But it doesn't do away with the need for your friendly and knowledgeable Arizona Auto and Radiator Repair service technician to make a proper diagnosis. Car care, like medical care, still requires the human touch.

The Arizona Auto and Radiator Repair Guide to Tire Specs

You know you need new tires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the Sierra Vista service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.

Tire size can be confusing for many Sierra Vista drivers. There's so much on the side of the tire, and it's hard to keep straight.

Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing for Sierra Vista tire shoppers. Let's start with the size number.

For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number.

The R signifies it's a radial tire. And 16 is the rim or wheel size in inches.

The 92 is the load rating index - it's the load carrying capacity of a tire. The higher the number, the more it can safely carry. Your empty vehicle can be safe with a lower number, but you'll need a higher rating if you routinely haul heavy loads around Sierra Vista. The next letter is the speed rating. Not all tires sold in Sierra Vista are speed rated. The ratings generally follow the alphabet: the further up the alphabet, the higher the speed rating - with the exception of H - it comes between U and V (don't ask why).

There's a lot of fine print that most Sierra Vista area drivers probably need a magnifying glass to read. But there are a couple of other large print items of interest. One is the tread type: highway, mud and snow, all season, severe snow, etc.

And then there are the Uniform Tire Quality Grading System markings. The first is a tread wear index. 100 is the base line - a lower number is poorer and a higher number is better. All things being equal, a tire rated 200 would wear twice as long, on a government test track, than one rated at 100. These wear grades are only valid within the manufacturers product line - you can't compare with others. And it's important to note that a lower rating might be just what you want - a high performance, sticky tire has a softer rubber compound and won't wear as long, but boy, will it take those corners on twisting AZ roads.

The next is a traction grade. This measures the tire's ability to stop on wet pavement in government tests. A - the best, B - intermediate, C - acceptable.

Temperature grade measures a tire's resistance to heat buildup in government tests. A, B and C - from best to acceptable.

It's safe for Sierra Vista drivers to go with the vehicle manufacturers original equipment recommendations that came on your car. But if you want to make adjustments, you'll now be better equipped to communicate with your friendly and knowledgeable Arizona Auto and Radiator Repair tire professional.

Introduction to Diesels for Sierra Vista, AZ

Something you're going to be hearing a lot about around Sierra Vista, AZ, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.

Most people in AZ are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in Sierra Vista, AZ. But that's about to change.

In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Sierra Vista, AZ, so we are now ready to start seeing more diesel options offered over the next few years.

Why are so many Sierra Vista drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. There's more power in a barrel of diesel fuel than there is in a barrel of gasoline. The result? Better performance and improved fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold in Sierra Vista with diesel engines?

If you think back to the late 1970's and early 1980's, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold in AZ have evolved considerably.

They are quiet, clean – and powerful. They're so refined that many Sierra Vista drivers can't even tell they're riding in a diesel powered vehicle. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

Another thing the Sierra Vista green crowd takes advantage of is the use of bio-diesel in diesel vehicles. Bio-diesel is made from vegetable oil – even recycled cooking oil from Sierra Vista restaurants. There is a lot of buzz about hybrid cars in AZ. Look to diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers introduce new diesel models. Look for diesels in domestic light trucks, SUVs and passenger cars. Import brands have plans to bring more of their outstanding diesel engines to AZ as well.

New Sierra Vista diesel owners need to know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it's important to keep your fuel system clean with a diesel.

The good news is that Arizona Auto and Radiator Repair in Sierra Vista is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

When we tell you to look for more diesels on Sierra Vista streets, you won't be looking for smoky tail pipes as a clue. You also won't be listening for that familiar big rig rattle. And, you certainly won't be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.

Fuel Filter Replacement

Hello Sierra Vista resident! You would never like to drink a glass of mud, right? Well, your vehicle feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your vehicle will still run. But, then the contaminated fuel can clog your fuel injectors and allow particles into your engine.

A vehicle with a partially clogged fuel filter might run well around Sierra Vista, but sputter and strain on the because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive in AZ and the gas you buy. If you drive a lot on dirt or gravel roads in rural AZ, your fuel filter will have a harder time keeping the fuel clean.

And, we hate to say it, but buying the cheapest gas from bargain stations sometimes means dirtier fuel that'll clog the filter sooner. Major brands tend to be cleaner and certainly have higher levels of detergent additives.

Of course, manufacturers recommend intervals for changing the fuel filter. But, it's a little more complicated than that for Sierra Vista residents. Some manufacturers stopped listing recommended intervals for fuel filter replacement or have very long intervals like every five years or 80,000 miles (130,000 kilometers). So you may need to look to other sources for recommendations. Vehicles older than six or seven years are especially at risk because they have had time for dirt and rust to build up in the fuel tank. A clean fuel filter keeps the gas flowing. Even a partially clogged filter puts added strain on the vehicle fuel pump. That can shorten its life and result in repair.

As is often the case, spending a little money now on something as inexpensive as a fuel filter can save money for Sierra Vista residents down the road by improving and preventing repairs. At Arizona Auto and Radiator Repair in Sierra Vista, we can check your fuel filter. It is better than fixing a burned-out vehicle fuel pump or ruined fuel injectors.
