Automotive Tips from Arizona Auto and Radiator Repair: A Broken or Damaged Timing Belt

The timing belt rotates the cam shafts which open and close the valves that allow air, fuel, and exhaust to flow through the engine as it powers your car when you drive around Sierra Vista.

An old timing belt can lose a “tooth” in the belt allowing it to slip. The engine could stop or misfire. Timing belt slips – or a broken timing belt – can be disastrous on some engines. In “interference” engines, open valves can get in the way of the piston when the timing belt breaks or slips. When that happens one or more valves can be bent requiring expensive engine repairs.

It is important for Sierra Vista drivers to replace their timing belts as recommended in their owner’s manual to avoid unnecessary breakdowns. Ask the team of professionals at Arizona Auto and Radiator Repair in Sierra Vista if it’s time for your timing belt to be replaced.

Fuel Saving Tip: Slow Down in Sierra Vista

There’s not much Sierra Vista drivers can do about the price of gas in AZ, but we can control - up to a point - how much we use. Our driving habits can dramatically affect our fuel economy.

The first thing we can do is watch the go-pedal. Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don’t need to floor it. That can save you hundreds of dollars a year in improved gas mileage.

Go a little slower on AZ expressways. Sierra Vista drivers who go more than 65 miles an hour (105 kilometers per hour) will see their gas mileage drop dramatically. Leave early so you don’t need to rush to be on time. And cruise control is your friend – steady speeds use less gas.

Plan errands ahead. Make fewer trips by combining errands around Sierra Vista.

Hey at current Sierra Vista gas prices, a lead-foot might as well be a gold foot.

TPMS: Tire Pressure Monitoring for Your Sierra Vista Vehicle

Sierra Vista drivers may know that all 2008 model year and newer cars, mini-vans and light trucks in AZ come with a tire pressure monitoring system. Many slightly older vehicles around the Sierra Vista area have these systems as well. A tire pressure monitoring system – called TPMS – consists of sensors on each wheel that measure tire pressure.

If tire pressure drops 25 percent below the vehicle manufacture’s recommended pressure, the sensor sends a signal to a monitoring unit that causes a warning to light up on the dashboard. When drivers see the warning light, they know it's time to put some air in the tires.

There are many benefits to people in Sierra Vista who drive with properly inflated tires. First is cost savings. Running at the correct air pressure improves fuel economy. Driving on underinflated tires is like driving through sand – it drags down your fuel economy. Drivers in Sierra Vista will also see longer, more even tread wear so your tires will last longer.

Another important benefit of properly inflated tires is increased safety for Sierra Vista vehicles. Underinflated tires become hotter, and that heat can actually lead to tire failure – possibly resulting in an accident. Your vehicle and the tires themselves will just perform better and more safely around Sierra Vista with properly inflated tires.

Local AZ consumer groups and law-makers advocate TPMS systems hoping that they will save lives, property damage and inconvenience. While you can't put a value on saving a life, Sierra Vista drivers should keep in mind that TPMS systems aren't free.

The systems themselves are added into the price of the vehicle. The batteries in the sensors will have to be replaced from time to time. Parts will break and need to be replaced. In colder climates around AZ, ice and salt are frequent causes of failure.

In addition, there are other behind-the-scenes costs we want you to be aware of. Every time a tire is replaced, repaired, rotated or balanced, the tire technician has to deal with the TPMS system.

Sierra Vista service centers such as Arizona Auto and Radiator Repair must purchase equipment used to scan and reactivate the TPMS system after every tire service. Because older tire change equipment can damage TPMS sensors, your Sierra Vista area service center may need to buy expensive, new tire changers.

Since there is no uniformity among manufacturers, technicians need to be trained on several TPMS systems. These behind-the-scenes costs are very real to Sierra Vista service center managers.

That's why the team at Arizona Auto and Radiator Repair is anxious for people in the Sierra Vista area to understand the financial impact of TPMS systems. In the past, we've been able to quickly and cheaply provide tire services and then pass the low cost on to customers as an expression of our good will. But now even these simple jobs take much longer and require equipment.

Sensors will need to be removed and reinstalled. Even a tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a vehicle battery is disconnected, the TPMS system will need to be reprogrammed.

So when you start so see the cost of tire changes, flat repairs and rotations going up in AZ, please keep in mind that it's because of this new safety equipment. The team at Arizona Auto and Radiator Repair just wants to keep you safely on the road – and we're committed to doing it at a fair price.

It's important to remember that the TPMS warning only comes on when a tire is severely underinflated. You'll still want to check your tire pressure regularly. At every fill-up is best, but you should check pressure at least once a month. Here's wishing you safe travels.

Everything You Ever Wanted to Know About Wheel Bearings

Why are wheel bearings for Sierra Vista vehicles important? It's simple: your wheel bearings keep the wheels on your vehicle. In today's Arizona Auto and Radiator Repair post, we'll discuss more about wheel bearings and how you can make sure they can do their very job while you drive around Sierra Vista, AZ.

Wheel bearings are pretty simple parts. They're made of high quality steel and are engineered to last 100,000 miles (160,000)  or more if properly cared for. The bearings do two jobs: First, they allow the wheel to freely rotate with as little friction as possible. Second, they support the weight of the vehicle. For example, if your car weighs 3,600 pounds (1600 kilogram), each wheel has to support approximately 900 pounds (400 kilograms). That's a lot of heavy lifting over those long distances.

Even though wheel bearings are pretty straightforward, they need to be in near perfect condition to do their job for Sierra Vista vehicles. The bearings are packed with heavy grease to lubricate and protect them. A seal keeps the grease in and water and dirt out. It's when the seal starts to leak that problems begin. The grease can become contaminated, causing the wheel bearings to overheat and ultimately fail.

The first sign that your wheel bearings are in trouble is an unusual noise coming from a wheel. It could be a chirping, growling, rumbling or a cyclic sound. The noise could get louder or even disappear at certain speeds. Your technician at Arizona Auto and Radiator Repair can inspect for bearing wear by lifting the vehicle and checking for play in the wheel.

Now some wheel bearing assemblies are factory sealed. That means that they cannot be serviced – they can only be replaced. Those that aren't sealed can be serviced on schedule at Arizona Auto and Radiator Repair. The bearings are removed, cleaned and inspected. If the bearings are still good, they're re-installed – if not, they're replaced. They are then packed in grease and a new seal is installed.

If your vehicle has a factory sealed wheel bearing assembly, the entire assembly needs to be replaced when trouble arises. Unfortunately, the parts are pretty costly – but they usually last about 150,000 miles (240,000 kilometers) as long as the seals hold up.

Now, even a good seal cannot keep out water that's exerting pressure on the seal. So if you've driven through hub-deep water, your bearings should be cleaned and repacked if they're serviceable. If you have factory sealed bearings, you just need to watch for signs of premature failure. If your wheel bearings can be serviced, your manufacturer's owner's manual will recommend an interval, usually around 30,000 miles (50,000 kilometers).

If you have any sort of trailer, don't forget its wheel bearings. They probably need to be serviced even more frequently. This is especially true for boat trailers that are used to launch the boat by backing it into the water. These should be serviced every year, usually at the end of the season so that the bearings don't have the opportunity to rust all winter.

So what happens to Sierra Vista vehicles if wheel bearings fail? Well, the wheel can literally fall off the vehicle. I don't need to tell you how that could be. So check with your service advisor at Arizona Auto and Radiator Repair and see if your vehicle's wheel bearings can be serviced and when it's recommended. Listen for warning signs. If you've been fording streams or puddle surfing after rainstorms, be especially vigilant.
