Deep Clean Your Fuel System at Arizona Auto and Radiator Repair

Having trouble with your fuel system? Bring your vehicle into Arizona Auto and Radiator Repair for a check up.

In today's Arizona Auto and Radiator Repair auto post, we're talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. Sierra Vista residents need fuel to go, and the cleaner the fuel system, the more efficiently the fuel will burn. That means more power and better mileage .

A clean fuel system saves money for Sierra Vista drivers at AZ gas stations. We guess you could say it all starts and ends at the pump. One of the most important things Sierra Vista residents can do to keep their vehicle fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas in AZ can actually be more expensive for Sierra Vista drivers in the long run. Now, most cars on AZ roads are more than five or six years old. That means they've had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your vehicle engine. That's the fuel filter's job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. So Sierra Vista residents should have their fuel filter changed when recommended. Check your owner's manual or ask your friendly and knowledgeable Arizona Auto and Radiator Repair service advisor if your fuel filter is due for replacement.

Recommended Sierra Vista Service Intervals

Everyone in Sierra Vista, AZ, knows we are advised to go to our Sierra Vista dentist twice a year.  Oral-conscious Sierra Vista residents have a teeth-cleaning and examination. Once a year, we get x-rays to look for problems that can't be seen with the naked eye. When our dentist is done, he/she tells us what was found – "Everything's fine, see you in six months." Or "You've got a small cavity starting, let's schedule an appointment to take care of it." By the time you leave, you have a plan for addressing any necessary issues.

This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.

If Sierra Vista folks understand the wisdom of using this system for handling dental care, why do many resist when facing the same system for our vehicle maintenance?

Following the vehicle manufacturer's recommended intervals can be confusing. First, there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing ...you get the point.

Every item has a recommended interval and it's hard for Sierra Vista drivers to keep it all straight – even if you're part of the 1% of AZ drivers that read their owners' manual.

And if you have more than one vehicle, the complexity is multiplied. You'd need a computer to keep track of everything. Well, that's how your service center does it. For example, Arizona Auto and Radiator Repair subscribes to automotive databases that have your vehicle's recommended intervals. You may have wondered how they know what else to recommend when you take your car in for an oil change – it's all in the database.

Well, it's not all in the computer. There are other variables that can't be accounted for in the schedule: Things like Sierra Vista weather conditions, altitude, and where and how you drive in AZ. Talk about these things with your service advisor at Arizona Auto and Radiator Repair and you may decide that the severe service schedule in your owner's manual is more appropriate.

Since anything that's not driving in moderate weather is considered severe and most of us do at least some of that around Sierra Vista, AZ, it should be taken into account.

Let's take your basic oil change as an example. What issues are involved? The oil you put in your vehicle is a blend of base oil and special additives. There are detergents to clean the inside of your vehicle engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.

Now, these additives deplete with use and time. That's why most vehicle manufacturer's maintenance recommendations include both a time and mileage element – like 3 months or 3,000 miles/5,000 km, whichever comes first.

It's easy for Sierra Vista drivers to think, "Gee, I've only driven 2,000 miles/3,200 km in the last 3 months. I can wait on that oil change." But you need to remember that the inside of your engine is a environment. The oil is contaminated with combustion by-products that start degrading its effectiveness even when it's just sitting there.

A lot of people in Sierra Vista don't realize how harmful it is to skip an oil change. There are a lot of metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it's clogged up because you haven't changed it, it can't trap any more.

Oil sludge is another problem for Sierra Vista vehicles. Sludge is oil that has turned to a gunky jelly – think 'Vaseline.' Obviously, sludge doesn't lubricate. It can also clog small oil passages so that all the parts don't get properly protected by the oil. That'll lead to premature wear.

If you've missed some oil changes, don't despair. Just talk with the pros at Arizona Auto and Radiator Repair. Fess up – you'll feel better. And they can help you get back on track. Following recommended intervals is the key to keeping your vehicle on the road and avoiding repairs.

When Are Your Tires Worn Out?

Hey Sierra Vista area drivers, are your tires worn out? What is the standard for our AZ streets? How can you tell on your vehicle?

While there may be legal requirements for the Sierra Vista area, there are safety concerns that go beyond meeting minimum replacement mandates.

Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.

We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.

In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up accelerated to 70 miles per hour, or 112 kilometers an hour, and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:

• New tire tread depth
• 4/32 of an inch, or 3.2 mm
• 2/32 of an inch, or 1.6 mm

So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, and it took 5.9 seconds.

Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 mph/89 kph with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch, or 3.2 mm – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. It took nearly 100 feet, or about 30 meters, more room to stop and 1.2 seconds longer. That's a big improvement. We can see why Consumer Reports and others are calling for a new standard.

Of course, stopping distances were greater for the heavier pick-up truck.

How do you know when your tires are at 4/32 inch or 3.2 mm? Easy; just insert an American quarter into the tread. Put it in upside down. If the tread doesn't cover George Washington's hairline, it's time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

You may remember doing that with pennies. A penny gives you 2/32 inch, or 1.6 mm, to Abraham Lincoln's head. The quarter is the new recommendation – 4/32 inch, or 3.2 mm.

How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?

For us, and we would guess for many, the answer is "no".

On Board Diagnostics for Your vehicle

Today we're going to talk about on-board diagnostics and the questions we hear from folks around Sierra Vista, AZ, who need answers about diagnostic services. They want to know what diagnostics are, what's involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Sierra Vista.

These are valid concerns. If you don't understand something it's really hard to know its value. Let's start with some history.

Since 1996, all cars and light trucks in Sierra Vista, AZ, have been required to use a standardized diagnostic system to help repair technicians determine what's wrong with your vehicle. The diagnostic system works with the vehicle's Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can't adjust for, the computer will turn on the Check Engine light.

It is also called the 'service engine soon' light on some vehicles. The warning light signals you to get into your local service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you've searched for Check Engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what's wrong.

That's a common myth. The code itself doesn't tell you what's broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won't tell you what's wrong or how to fix it.

Let's say you think your daughter has a fever. You take her temperature and it reads 102 degrees F/38.9 degrees C. You've confirmed a fever, but you don't know what's causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician's examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads 'Bank 1 sensor 1 circuit slow response.' This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that's all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that's stored in the engine control computer. That history's very helpful in diagnosing the problem. Service centers like Arizona Auto and Radiator Repair invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don't need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your Check Engine light comes on, get it checked at Arizona Auto and Radiator Repair. If the light burns steadily – don't panic. Get in to Arizona Auto and Radiator Repair soon to have the engine scanned. A flashing Check Engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing Check Engine light.

Make an appointment with Arizona Auto and Radiator Repair to have your on board diagnostics analyzed.

Diesel Maintenance for AZ

At Arizona Auto and Radiator Repair we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV's. But our AZ friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there're nearly as many diesel powered passenger cars as there are gasoline.

Here's who's announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in AZ.

You may ask, why has it taken so long getting to AZ and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that AZ diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up AZ to the engines the rest of the world's been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there's none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

Repair costs are similar to vehicles with gas engines. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system and so on. And the payoff for you, if you're the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for many, many years.
