Cool Breeze: Air Conditioning Service at Arizona Auto and Radiator Repair in Sierra Vista

Most AZ auto owners know that their vehicles need regular preventive maintenance like changing the oil and filters, rotating the tires and refilling the washer fluid. But did you know that your air conditioning system needs routine maintenance as well? Taking care of your air conditioning system can extend its life and prevent costly repair bills.

Why is it important for Sierra Vista area drivers to get routine maintenance on their air conditioning system? First, the refrigerant contains an added lubricant. As the refrigerant circulates through the air conditioning system, its parts are lubricated. This constant lubrication keeps the parts functioning well. But over time, this lubricant is used up, and without it, the parts will eventually seize up and fail.

Sierra Vista folks should understand, however, that the air conditioner will continue to pump out cool air even without the lubricant, so you won't know the system is sick until it actually dies. So good vehicle care includes regularly checking the refrigerant and lubricant in your vehicle air conditioning system and replacing it if needed.

The second reason your air conditioning system needs preventive maintenance is that air and water can get into the system. Air, water and the contaminants they contain will reduce the efficiency of the air conditioning system and can cause corrosion of the system's parts. Keeping the air conditioning system clean is a practice that will extend its life and keep you from losing your cool on hot Sierra Vista days.

How often should you get a routine car air conditioner inspection? It varies from vehicle to vehicle. Check your owner's manual for the vehicle manufacturer's recommendation.

Here's a good piece of advice from Arizona Auto and Radiator Repair for AZ vehicle owners that will extend the life of their air conditioning systems: You should run your air conditioner in the winter every once in a while. This circulates the refrigerant, which lubricates the seals. That way, they won't dry out during cold Sierra Vista weather.

Cool Running in Sierra Vista

Unless you live in Death Valley, you really don't hear much any more about cars overheating. That's because cooling systems in vehicles have been much improved. That doesn't mean you can't overheat your vehicle engine, though. Without proper preventive maintenance, you could still find yourself on the side of the road in Sierra Vista waiting for your vehicle engine to cool down.

When you service your cooling system at Arizona Auto and Radiator Repair, your technician will check the condition of the coolant. It can become corrosive over time, which can damage a radiator — leading to an overheated engine. Changing the coolant periodically is good vehicle care. Your vehicle owner's manual can give you guidelines on how often to replace it.

If your engine overheated, your friendly and knowledgeable service advisor will also check your coolant system for leaks. Check the vehicle radiator for cracks and the radiator hoses for leaks. He'll also check your water pump. They don't need to be replaced on a regular schedule, but they do need checked regularly. They can and do wear out.

The water pump is a critical component of your vehicle cooling system. It pumps the coolant to keep it circulating through the engine. The coolant is cooled in the radiator, then it travels through the engine, where it absorbs heat, then it returns to the radiator, where it releases the heat. And so on. But a water pump is something of a misnomer. The fluid pumped through your vehicle cooling system is not just water. It also contains coolant, which is actually poisonous. You should never consider your radiator as an emergency water supply.

There are many types of coolant. It varies from vehicle to vehicle, and using the wrong kind could damage your engine. Your service advisor will know which kind your vehicle's manufacturer recommends. The team of automotive professionals at Arizona Auto and Radiator Repair is always a good source for auto advice. We've been providing quality automotive services at our convenient location in Sierra Vista for years.

At Arizona Auto and Radiator Repair, we help you keep your cool which will keep you in the driving lane.

What’s Up With Diesels in Sierra Vista?

Would you be surprised to learn that about half of the passenger cars in Europe have diesel engines? You might also be surprised to learn that most manufacturers produce a variety of diesel-fueled cars for purchase abroad.

Diesel-fueled vehicles haven’t been as popular in the North American markets like AZ. But that won’t be true for long. North Americans are seeing a lot more diesel-fueled vehicles on the road. And we’re not talking about buses and trucks. These vehicles will be passenger cars, pick-ups and SUV’s.

There are two reasons for this. The first is a recent change in environmental laws that have upgraded emissions standards for diesel fuel in North America. Diesel fuel in North America used to have higher sulfur content than European fuel, meaning that it was a dirtier fuel to burn. That was okay for larger vehicles, but the lighter-weight engines in passenger vehicles just couldn’t tolerate it.

But that high sulfur content is now a thing of the past. Fuel producers are now required to sell cleaner diesel fuel in Sierra Vista. That opens the North American market to more diesel-powered vehicles. The second reason we’re going to see more of these vehicles in Sierra Vista is that they’re more fuel-efficient than their gasoline-powered counterparts. Diesel fuel has higher energy density than gasoline. That translates to more power per barrel of fuel. In your tank, that translates to better engine performance and about 20% more miles per gallon.

Sierra Vista drivers may associate diesel engines with black smoke, noise and a definite “shake, rattle and roll.” That’s also a thing of the past. Modern diesel engines are smooth and quiet and produce cleaner emissions than gasoline engines. Also, forget that three-second wait behind a diesel vehicle at a stoplight. Modern diesels are just as quick to accelerate as other vehicles on Sierra Vista roads.

Diesel engines have other advantages over gasoline engines. Diesel engines are heavier than gasoline engines because they require more heavy-duty parts, but that means the engines are more durable and can last longer than gasoline engines. Also, diesel engines may be the engines of the future since they can burn many of the new bio-fuels.

Bio-diesel can be manufactured from vegetable oils, including used cooking oil from Sierra Vista restaurants. Just think, one day you could fuel your vehicle on stuff that was once considered waste—one step closer to a cleaner environment here in AZ. And if you think hybrid cars are environmentally sound, consider what a diesel-electric hybrid could mean. They will soon be available for
Sierra Vista auto owners.

Sierra Vista auto owners who are considering buying a diesel-fueled vehicle, should know that important preventive maintenance and inspection schedules are different for a diesel engine than a gasoline engine. Diesel fuel is harder on emissions systems than gasoline, so the filters and other devices have to be changed and checked more often. Also, the fuel injection system operates at much higher pressures for diesel than for gasoline, so keeping it clean becomes a higher priority.

When you switch from a gas vehicle to a diesel, you’ll have to learn some new rules of car care. But you won’t be alone. Most
Sierra Vista service centers are aware that diesels are coming to North America and are already prepared to provide service for diesel engines. At Arizona Auto & Radiator Repair, we are well-versed in diesel technology. You can rely on our team of automotive professionals to provide quality service for diesel powered vehicles.

Clean Air for Your Engine: A New Engine Air Filter at Arizona Auto and Radiator Repair

All of us in Sierra Vista know we have to get the oil changed in our vehicles periodically. That's just part of good vehicle care. But when Arizona Auto and Radiator Repair technicians change your oil, they also usually inspect your air filter. That's why they sometimes let you know that your air filter needs to be changed before releasing your vehicle.

Don't just chock this up to trying to sell you something else. Sierra Vista area drivers really do need to change their air filter when it gets dirty. You can check your owner's manual to see how often your air filter should need to be changed, but remember, if you live in an area in AZ with poor air quality, or if you drive a lot or drive under harsh conditions in the Sierra Vista area, you may need to change that filter more often than is recommended.

Changing an air filter isn't guesswork. If a filter's dirty, it needs to be replaced. Air filters aren't very expensive at Arizona Auto and Radiator Repair. But the problems they cause if Sierra Vista auto owners don't change them can get to be.

How Much is Enough for Sierra Vista Auto Owners? Tire Tread Depth

Most Sierra Vista drivers know that tires wear out and that the wear has to do with tread depth. Most of us have heard that “bald” tires are dangerous, but most of us picture a tire with no tread at all when we think of a bald tire. And when we take our vehicles in for preventive maintenance, the technician tells us they're need to be replaced long before all the tread is worn off. Just how much tire tread wear is too much? And how can you tell? Tires are and their condition is important to the safe handling of a vehicle, so it's for Sierra Vista vehicle owners to know the answers to these questions.

First of all, it's important to understand that there may be a legal limit to tread wear. If your tires are worn past this limit, you have to replace them to be in compliance with AZ auto safety laws. That's why measuring your tread wear is part of a vehicle safety inspection.

In some jurisdictions, tread must be at least 1.6 millimeters or 2/32 of an inch thick. This standard has been in effect since 1968. But this standard has recently been called into question, and some AZ professionals are arguing that it be changed.

The safety issue that has brought this standard under scrutiny is the ability of a vehicle to stop on a wet surface. When a vehicle has trouble stopping, most Sierra Vista drivers immediately look at the brakes as the source of the problem. But tires are crucial to safe stopping distances because they provide the traction required in a stop.

A tire's contact with the road surface creates traction, which allows for effective braking. On a wet surface, a tire only has traction if it can get to the road's surface. So tire tread is designed to channel water out from under the tire to allow it to stay in contact with the road. If the tire can't shift the water, then it starts to “float.” This condition is called hydroplaning. It is very dangerous for Sierra Vista drivers since the vehicle won't stop no matter how hard the driver presses the brakes. Steering control is also lost.

A recent study tested the stopping ability of a passenger car and a full-sized pick-up on a road surface covered with only a dime's depth of water (less than a millimeter). The vehicles were traveling at 70 mph (112 kph) when they stopped on the wet surface. At 2/32 (1.6 mm) tread depth, the stopping distance was double that of a new tire. The passenger car was still traveling at 55 mph (89 kph) when it reached the stopping distance it experienced with new tires.

Let's suppose that you're on a busy Sierra Vista road in a light drizzle and a vehicle stops suddenly in front of you. You just bought new tires and you brake hard, missing the vehicle with only inches to spare. If you hadn't bought those new tires, you would have crashed into that vehicle at 55 mph (89 kph). That is a major difference.

What if your tires had a tread depth of 4/32 (3.2 mm)? You would have crashed into that vehicle at 45 mph (72 kph). Still not a good situation. But it's better.

Now what if you were driving that pick-up truck? You wouldn't have missed that vehicle in the first place, and you would have crashed at higher rates of speed in both of the other scenarios. The heavier your vehicle, the longer its stopping distance. It's a matter of physics.

The results of this test has led Consumer Reports and others to ask that the standard for tread wear be changed from 2/32 (1.6 mm) to 4/32 (3.2 mm). The increased standard will improve safety on the road and save lives here in AZ and nationally.

Of course, until the standard changes, you'll have to decide whether you'll be willing to replace your tires a little sooner.

You can use an American quarter to tell if your tread wear is down to 4/32 (3.2 mm). Place the quarter into the tread with George's head toward the tire and his neck toward you. If the tread doesn't cover George's hairline, you're under 4/32 (3.2 mm). With a Canadian quarter, the tread should cover the digits of the year.

You can measure the 2/32 inch (1.6 mm) tread wear with a penny. If the tread touches the top of Abe's head, it's at 2/32 (1.6 mm). Tires are super important when it comes to vehicle care. But their condition has a major impact on safety. We need to decide whether to sacrifice safety for economy. Keeping our tread wear above 4/32 in (3.2 mm) is good auto advice.
