Timing Belt Replacement in Sierra Vista

Today we want to talk to Sierra Vista drivers about timing belts. They're something that many drivers don't know much about and yet your vehicle won't run if it's broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner's manual, it's not the kind of thing that most Sierra Vista area auto owners remember because it's not well understood.

Let's review what a timing belt does. As most know, the engine's power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel, pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It's called a timing belt because the valves have to open and close at just the right time.

Now, not all vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. The leading vehicle manufactures started using belts rather than chains to save money in the manufacturing process. So now Sierra Vista drivers and their advisors at Arizona Auto and Radiator Repair are left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous for drivers depending on where they are at the time, but it causes no internal engine damage.

Interference vehicle engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it'll cost a chunk of change to repair the vehicle engine.

So, what are the warning signs? Unfortunately, there really aren't any. There aren't tell-tale sounds. In some vehicles, a technician from Arizona Auto and Radiator Repair may be able to see part of the belt for a visual inspection, but many have a cover that's in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it'll cause. There's no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner's manual calls for it. It can be 60,000 miles/97,000 km; it might be 90,000 or 100,000 miles/145,000 or 160,000 km. The point is, if you have 60,000 or more miles (97,000 or more km), ask your Arizona Auto and Radiator Repair service advisor right away if your vehicle requires a timing belt replacement.

Sometimes Sierra Vista drivers can go quite a while without a failure, but we've seen them happen within a couple of oil changes of being due. It's not worth the risk.

What does it cost to replace a timing belt in Sierra Vista? Well, that really depends on what kind of car you have. I can tell you that it's usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn't a cheap procedure, but it's a fraction of what it could cost to repair the damage caused by a failure.

At Arizona Auto and Radiator Repair in Sierra Vista, we're all about trying to prevent repairs, keeping you and your passengers safe and increasing your driving enjoyment. 

Keeping Your 'Old Faithful' Auto Running

At Arizona Auto and Radiator Repair we've had a lot of Sierra Vista customers asking how they can make their vehicles last longer. These questions are actually a reflection of a trend that's been building for several years in AZ. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles (120,000 km) on them. It looks like it's going to keep heading in that direction for a while. With high fuel prices, a lot of AZ folks are putting off buying a new car. 

So let's say you're one of the average in the Sierra Vista area; you've got a nine-year-old car with 80,000 miles (130,000 km) on the odometer. What can you do to make it last another year or two?

Let's start with the premise that there's no reason that a modern car can't run for 200,000 miles (320,000 km) with proper care in Sierra Vista. The engineering and manufacturing quality is there.

Of course, some parts will wear out along the way, but there's no reason for a catastrophic meltdown if Sierra Vista drivers stay on top of their recommended car maintenance. The maintenance schedule in some vehicle manufacturer's owner's manuals runs out at 60,000 miles (100,000 km) or so: how do Sierra Vista vehicle owners know what to do when they're way past that?

It is a challenge, for example: If a service is recommended every 15,000 miles (24,000 km) for the first 60,000 miles (100,000 km), you can just keep getting it done at least every 15,000 miles (24,000 km) after you hit 60,000 miles (100,000 km). But, it gets more complicated because older engines lose some efficiency, are dirtier inside and are just more stressed. That means it's very important to not miss any scheduled services. Skipping just one oil change at Arizona Auto and Radiator Repair in Sierra Vista, for example, leaves an opportunity for sludge to build up. Talk to your service advisor at Arizona Auto and Radiator Repair for more details.

So all the usual things like oil changes, transmission service, coolant service, brakes, power steering, fuel system cleaning – all that stuff needs to be maintained. People responsible for fleet vehicles around Sierra Vista are sticklers for scheduled maintenance. They know that money spent on maintenance saves them three ways:

1. it keeps efficiency from decreasing;
2. it prevents repairs, and;
3. they can postpone purchasing new vehicles.

Having the oil changed may be the most important thing Sierra Vista drivers can do. A full-service oil change at Arizona Auto and Radiator Repair means that all of your other fluids get topped off so they are never low enough to cause damage. It also gives your friendly and knowledgeable Arizona Auto and Radiator Repair service advisor a chance to spot problems in the early stages so that you can fix them before they get worse. And it gives you a touch point with an automotive professional along the way to remind you of things that aren't scheduled as often – things like differential service and timing belt replacement.

If you live in the Sierra Vista area and have an older vehicle, you may need to follow the severe service maintenance schedule. Check your owner's manual and talk with us at Arizona Auto and Radiator Repair. Conditions inside an older engine, transmission and cooling system can arguably be considered severe – so shorter intervals could well be called for.

And, the team at Arizona Auto and Radiator Repair strongly encourages Sierra Vista drivers to consider using high mileage formulation fluids. They're fluids like engine oil, transmission fluid and coolant that are formulated for older engines. They have special additives to clean deposits, and to condition and restore seals and gaskets that dry out with age. Some Sierra Vista auto owners start using higher mileage formulations at around 50,000 miles (80,000 km) as a preventive measure.

Of course you also want to still look marvelous in your older car as you drive around Sierra Vista. Salt and road grime wreak havoc on your paint job and can lead to body rust – so regular washing is very important. Also, a good quality waxing is recommended at least twice a year.

Fuel Injection Basics for Sierra Vista

All modern Sierra Vista vehicles come with fuel injection systems, so it's a topic Sierra Vista drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.

So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in Sierra Vista, AZ. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

Arizona Auto and Radiator Repair can help Sierra Vista drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn't get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel? How does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It's tempting to shop for bargains in Sierra Vista with fuel prices as high as they are, but major brands in the Sierra Vista, AZ, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it's clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It's important to replace the fuel filter when your manufacturer recommends it. That's part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Sierra Vista drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There's no room for dirt and gum in a precision part like that.

There are a lot of good products available in Sierra Vista, AZ, that can clean fuel injectors. They're best used to prevent fouling in the fuel injectors. Many can't clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Arizona Auto and Radiator Repair in Sierra Vista. But putting the cleaner in the fuel tank after you've had Arizona Auto and Radiator Repair take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your vehicle may be ready for a fuel injector cleaning.

Keeping Your Car Young in Sierra Vista

As Sierra Vista consumers, we live in a disposable society. It's amazing all the stuff we throw away.

New stuff comes out so fast in AZ, and much of it is fairly cheap, so we just toss the old and move on. It seems like when we were kids our parents were real sticklers about taking care of our stuff - especially parents who grew up in the Depression. You know, hang up your clothes, polish your shoes, put away your toys. If something got lost or ruined by neglect, tough; we had to do without. 

We couldn't afford new cars very often, so we tried to make them last as long as we could. It's a good thing that cars are more reliable these days. They just don't break down as often. And the good news for us Sierra Vista penny pinchers is that a modern car can easily go 200,000 miles (320,000 km) with proper care. The engineering's there and so is the manufacturing quality. The missing ingredient is us making sure we follow the vehicle manufacturer's maintenance schedules.

Is it really that bad for Sierra Vista motorists to get off schedule? Well, it all adds up. Every time you go a little longer than the recommended interval  between oil changes, you've created an opportunity for  sludge to form and clog passages. Then some parts don't get oiled and they start to wear out faster. 

Skip a cooling system service, and the corrosion inhibitors become depleted; the radiator starts being damaged, one step closer to a failure. The same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.

It's also even more important for older vehicles in the Sierra Vista area. Those engines and other systems have had more time to get dirty, so they're working harder anyway. But it's never too late for Sierra Vista drivers to get back on track with maintenance and to hold off further damage.

It's just another example of our parents knowing what's best. (Surprising how often that happens.) And it really does start with the oil change, just like Dad said. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. That's like your safety net; go in for oil changes on time, and let the pros at Arizona Auto and Radiator Repair in Sierra Vista help you keep track of the rest.

Of course, it is inevitable for vehicles that some things are going to wear out along the way, like alternators, water pumps and such; they don't last forever. But that stuff is cheaper than a new car payment. And taking care of problems early means they have less time to cause other problems. It's like having high cholesterol; you don't want to wait for a heart attack before you address it.
