Right or Left? Arizona Auto and Radiator Repair Power Steering Service

Have you ever driven a vehicle without power steering? If you have, then you probably appreciate how much easier it is to drive today's modern vehicles. Before power steering, all of the force to turn a vehicle had to come from the driver's arms. That's why old cars had such large steering wheels: they needed plenty of leverage to steer. There were some Sierra Vista folks who had difficulty driving because they just weren't strong enough.

Power steering is now standard on all vehicles, but there are several ways that power can be delivered. Most vehicles use a hydraulic power steering system system. In this system, a serpentine belt from the engine powers a pump that pressurizes the power steering fluid. The pressure activates hydraulics that provides steering power.

Other vehicles use an electric pump to pressurize the power steering fluid rather than the belt-driven pump. Some newer vehicles actually have electric motors that provide steering power and don't use steering fluid at all, especially in the increasingly popular hybrid and electric vehicles.

Sierra Vista drivers who own a vehicle that uses power steering fluid need to have it changed regularly. Over time, moisture accumulates in the power steering fluid, which affects steering performance and can corrode steering components. Dirt and other contaminants can also accumulate in the power steering fluid, which will also negatively affect steering performance. A good power steering service at Arizona Auto and Radiator Repair in Sierra Vista will flush out the old fluid and get rid of dirt and other deposits in the system. Clean fluid will then be added. Fresh fluid provides lubricants that help protect the steering system as well as prevent corrosion.

For recommendations on how often your power steering fluid should be replaced, consult your owner's manual. It varies by vehicle model and manufacturer. For more auto advice on steering fluid changes—and other preventive maintenance—you can talk with your service advisor at Arizona Auto and Radiator Repair. You may need to change your fluid more often depending on the driving and weather conditions in your area.

Sierra Vista drivers who believe in good vehicle care will add power steering service to their preventive maintenance schedule. This will prevent damage to your steering system and extend its working life. The old days of double-handed cranking on a huge steering wheel may be over, but our new comfort and convenience are not maintenance-free. Do yourself and your vehicle a favor. Keep the power steering fluid clean.

Serpentine Belt Service at Arizona Auto and Radiator Repair

Most Sierra Vista folks occasionally have days when they've got a bunch of errands to run. Yesterday was my day off and I needed to fill the gas tank, pick up some groceries at my Sierra Vista market, swing by the ATM and get the kids from school. I could have made four trips . . . but that would have been totally inefficient. Instead I got unusually organized and planned my stops. I hit the ATM first and got gas next. Then I went to the supermarket and picked up the kids on the way home. I was proud of my wise use of time and money.

What does this have to do with your car? Well, back in the day, each of your engine's accessories, like the alternator and air conditioner, were powered by separate belts. A vehicle might have five or six belts. These days, vehicles have a single belt to run all the accessories. It's called the serpentine belt. A pulley attached to the vehicle engine's crank provides the power to turn the serpentine belt. On the engine in the video, the first accessory in line is the power steering pump, which makes it easier to steer your vehicle.

Next comes the alternator which powers the vehicle's electrical system and charges the battery. Then the air conditioning compressor. This helps make cold air to keep you comfortable all summer long in Sierra Vista. Finally, we come to the belt tensioner. Its job is to apply pressure on the belt to keep it tight. Then, back home to the crank.

This is a pretty typical setup, but it can vary somewhat. In some vehicles the water pump or radiator fan or the power brakes are also run by the serpentine belt. Some even have two serpentine belts. No matter how your engine is laid out, you're not going far without a serpentine belt. Your vehicle manufacturer has a recommended interval for replacing your belt and your Arizona Auto and Radiator Repair service technician can inspect it for damage or wear.

Several years ago, manufacturers started making serpentine belts out of a new material. It's much more durable, but it's harder to tell when the belt needs to be replaced. The old style belts would crack and chunks would fall off so you could easily see when you needed a new one.

On the new style belts, if the ribs wear too deep, it's time to replace. Your Arizona Auto and Radiator Repair technician uses a simple gauge to tell when the belt is worn.

A worn belt stresses your vehicle engine's expensive accessories and causes them to wear prematurely. So, change your serpentine belt and belt tensioner according to your manufacturer's recommendations to extend the life of your accessories and to prevent future breakdowns.

Give us a call.

On Board Diagnostics for Your Engine

Starting in 1996, Arizona Auto and Radiator Repair service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at Arizona Auto and Radiator Repair. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. Sierra Vista drivers need to understand that doing so can cause major damage.

When a vehicle is brought to Arizona Auto and Radiator Repair in Sierra Vista because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your Arizona Auto and Radiator Repair technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at Arizona Auto and Radiator Repair exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at Arizona Auto and Radiator Repair. But the ensuing process of actually diagnosing a vehicle's trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for Sierra Vista vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn't indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don't have the ability to read the history stored in an engine's computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. Arizona Auto and Radiator Repair invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it's good auto advice to use Arizona Auto and Radiator Repair for your car care. In the long run, it can save you time, unnecessary expense and frustration. Arizona Auto and Radiator Repair can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.
