What Is That? Check Engine Light Service at Arizona Auto and Radiator Repair

Okay. You went to your local Sierra Vista car wash, and while your vehicle was under the dryer, the Check Engine light started flashing. Panic! What did you just do? Something is seriously wrong with the vehicle! You head for the nearest Sierra Vista service center, but on the way, the Check Engine light stops flashing and just glows red. Hmm. Maybe things aren't as bad as they seem. You decide to wait until payday to take your vehicle in to get serviced. In the meantime, the Check Engine light goes off. What? You decide the light must be faulty; maybe when it comes on it doesn't mean anything, or maybe it's just in your vehicle as some sort of scam to get you to pay for unnecessary repairs. You're glad you didn't take your car to the Sierra Vista repair shop and resolve to ignore that Check Engine light in the future.

Whoa! Let's look at what really happened. Your vehicle was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered; there shouldn't be that much airflow when the vehicle engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The Check Engine light starts flashing, letting you know you need to take immediate action to prevent that damage.

You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the Check Engine light to stop flashing. The vehicle doesn't need immediate attention; but there was a problem, and it should be checked out by your Arizona Auto and Radiator Repair service advisor. After a few days the computer senses that the problem is gone, so it turns off the warning light.

You may think this story illustrates the uselessness of a Check Engine light, but you should remember that a computer can't think for itself; it can only follow its programming. It doesn't know the difference between a car wash air dryer and a serious malfunction in your vehicle engine. That doesn't make it useless. It just means you have to be the smart one.

Being smart doesn't mean ignoring your vehicle Check Engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.

Your engine computer is constantly collecting data about what is going on inside your vehicle engine. It knows what parameters are normal and when a reading may indicate a problem. It uses the Check Engine light to let you know when something isn't right. It then stores a code in its memory — which a technician can retrieve — that indicates which reading was abnormal.

The technician uses this code as a starting place to find out what's wrong with your vehicle. It's like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what's causing it. It's probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what's NOT wrong with you. Fevers don't accompany stress headaches, ulcers or arthritis, so there's no sense in testing for those conditions.

The pros at Arizona Auto and Radiator Repair respond to a trouble code in your vehicle's computer in the same way. The code doesn't say exactly what's wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn't need to look.

Now, you wouldn't consider diagnosing yourself with a serious medical problem — good medical advice unless you're a doctor. So you shouldn't consider trying to diagnose your vehicle's troubles by yourself — good auto advice unless you're a trained mechanic.

There are cheap scanners available on the market, and some Sierra Vista auto parts stores offer to read trouble codes from your vehicle engine's  computer for you. But these are really not good alternatives to taking your vehicle to a qualified service center such as Arizona Auto and Radiator Repair in Sierra Vista. Your engine's computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can't read an engine computer's long-term memory nor can they interpret manufacturer-specific codes. That's why our manager at Arizona Auto and Radiator Repair spends a lot of money on high-end diagnostic tools.

It's as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?

Getting your codes read at your Sierra Vista area auto parts store isn't really a money-saver, either, unless you're a trained mechanic. You'll end up with a code that tells you a symptom. What usually happens next is that the Sierra Vista area parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It's actually cheaper to just go to Arizona Auto and Radiator Repair and get things fixed right the first time.

Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it likely won't help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?

Part of good vehicle care is knowing where you can get a problem fixed — and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let's do it right the first time at Arizona Auto and Radiator Repair.

Vive la Differential at Arizona Auto and Radiator Repair in Sierra Vista

There are a lot of drivers in Sierra Vista who are due for a differential service, but had never heard of a differential before. With front-wheel drive being so common in AZ these days, the differential is just taken care of during a transmission service, so most Sierra Vista folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in Sierra Vista to not know they have a differential, let alone know that it needs service.

To better understand what a differential does, think about a track at any AZ high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside vehicle wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars weigh between 3,000 and 6,000 pounds (1,400 and 2,800 kg) – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So manufacturers recommend intervals for when to replace your differential fluid.

Your knowledgeable Arizona Auto and Radiator Repair service technician will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He'll then replace the fluid and install the additives if necessary.

Your Arizona Auto and Radiator Repair service advisor can look up the vehicle manufacturer's recommended service interval or you can check your owner's manual.

At Arizona Auto and Radiator Repair, we've been providing quality automotive service for our valued Sierra Vista customers since . If you need to schedule differential maintenance, or any other automotive service, give us a call at 520-459-2216.

Line ?Em Up: Wheel Alignment Service At Arizona Auto & Radiator Repair

Hello Sierra Vista car owners! Let's talk about alignment. One of the most important parts of preventive maintenance for your vehicle is keeping the wheels in alignment. Poor alignment causes your tires to wear unevenly, which can significantly reduce their lifespan. This means you will have to replace them more often, which can be costly in Sierra Vista.

It can even damage your suspension system, which is an expensive repair. But even more importantly, uneven tread wear can lead to blowouts on the road, a dangerous and potentially deadly safety risk for Sierra Vista drivers and their passengers.

It may not take an accident or bad driving habits to “knock” your tires out of alignment. Tires can go out of alignment with just everyday AZ driving. Sierra Vista road hazards, pot holes, uneven or gravel roads, even the bumps and bounces of normal Hereford freeways and surface streets can gradually put your van tires out of alignment.

So it’s good auto advice to have your van's alignment inspected periodically. Your vehicle’s owner’s manual will have recommendations on how often you should get an alignment check: usually every year or two. But if you think your van tires might be out of alignment, you should take your van into Arizona Auto & Radiator Repair now.

When you take your van in for an alignment in Sierra Vista, your thoughtful Arizona Auto & Radiator Repair service advisor will start by inspecting the steering and suspension systems. If something is broken or damaged there, it will need to be repaired in order to get good alignment of the wheels.

If all looks good in the steering and suspension departments, the van will then be put on an alignment rack where an initial alignment reading is taken. The wheels can then be aligned to the auto manufacturer’s specifications. The ideal alignment for any vehicle is set by its engineers and may vary from vehicle to vehicle.

There are three types of critical adjustments that may have to be made to correctly align a vehicle’s tires. The first is called “toe.” This refers to tires that are out of alignment because they point inward or outward at the front of the tire. Think of a person who is pigeon-toed or splay-footed, and you get the idea.

The second adjustment is the camber. This adjustment affects the angle at which the tires meet the road. Think of a solid building in contrast to the Leaning Tower of Pisa.

The last adjustment is the castor. This adjustment measures the angle of the tire in relation to the front axles. So, a piece of auto advice that just might be good for life as well: keep everything in alignment, and you’ll be able to steer where you want to go in Hereford. Drive safely.

Smart Sierra Vista Drivers Protect Against Overheating

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Sierra Vista drivers to prevent.

The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again.

The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage.

Different engines require different types of coolant/antifreeze. The owner's manual will list what kind a vehicle requires. Using the wrong type or mixing different types of coolant/antifreeze may void the warranty on the cooling system and may damage it as well.

Insufficient coolant can lead to engine failure. Coolant levels need to be checked regularly and topped off as necessary. If coolant levels drop quickly or consistently, the cooling system should be inspected for leaks. Coolant/antifreeze contains additives that protect the radiator and other coolant components from rust, scale and corrosion. Over time, these additives are depleted, so it is necessary for Sierra Vista drivers to replace coolant at specified intervals. Changing coolant should be part of routine preventive maintenance for any vehicle.

This service is often ignored, though, since old coolant still cools the engine. Vehicle owners don't realize there is a problem until the system fails. They are left with major repairs and possibly a damaged engine, which could have been prevented with a cooling system service at Arizona Auto and Radiator Repair in Sierra Vista.

If your vehicle sends a warning message to check its coolant or if the temperature gauge is reading in the red or hot zone, then the cooling system needs serviced. This service is critical and should not be put off since the potential for damage is high.

In an emergency situation, water or antifreeze can be added to your vehicle so that it can be driven to a service center for proper car care. For this reason, your owner's manual contains instructions for how to top off insufficient coolant – allow 45 minutes for the engine to cool before attempting to add coolant or water. However, the fluid should be added to the coolant overflow bottle, not to the radiator itself. Removing the radiator pressure cap can result in severe burns.

Topping off in an emergency, however, does not fix the problem. The vehicle should immediately be taken to Arizona Auto and Radiator Repair in Sierra Vista where they can inspect the cooling system, repair any leaks and clean it if necessary. They can identify what caused the emergency situation in first place and ensure it doesn't happen again.

Regular maintenance of a vehicle's cooling system is just good auto advice for Sierra Vista drivers. Cooling system service is relatively inexpensive and doesn't take long at Arizona Auto and Radiator Repair. Lack of it, however, can put a vehicle in the scrap heap.
