Automotive Tips from Acheson Auto Works: Brake Noise

Your brake pads are the important parts that rub against the rotor (or disc) to slow and stop your car when driving in CLIVE. They eventually wear down.

When your pads are worn too much, they won’t stop your vehicle as well. When the friction material is worn away, metal parts of the pad are exposed and you’ll hear a squeal or grinding sound.

That’s when CLIVE drivers should replace their brake pads at Acheson Auto Works. Not only will new pads restore your stopping power, but replacing them on time will prevent damage to the rotor.

If your brakes are making noise, ask your Acheson Auto Works service advisor to inspect your brakes. Addressing problems early will restore your safety and prevent expensive brake damage.

Fuel System Cleaning at Acheson Auto Works in CLIVE for Better Performance

A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine.

Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel economy and loss of engine performance.

So it's important to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name IA fuel companies also deliver a more consistent quality of fuel than do bargain stations in the CLIVE area.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Check your owner's manual or ask the pros at Acheson Auto Works in CLIVE to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.

You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won't be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.

If your fuel injectors are gummed up, you can get a professional deep cleaning service at Acheson Auto Works in CLIVE that will result in better fuel economy and improved vehicle performance.

Good vehicle care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.

Under Pressure in CLIVE: TPMS

test2 Have you noticed an increase in price when you get a flat tire fixed in CLIVE, or have your tires rotated? It might be the result of your TPMS, or Tire Pressure Monitoring System.

The federal government began requiring a TPMS system on 2008 model year passenger vehicles and light trucks. Some 2006 and 2007 models may have them as well. The system has a warning light that is mounted on the dashboard that will go on if one of the tires becomes severely underinflated.

Why the new requirement? Because underinflated tires are the number one cause of tire failure. Tire blowouts cause crashes and sometimes fatal accidents. Underinflated tires also need longer stopping distance and can skid, both of which also present dangers on IA roads. Many flat tires can also be prevented by proper tire inflation, and though this may seem an economic consideration, CLIVE drivers who have changed a flat on the side of the road recognize that this has serious safety concerns as well.

Advances in tire technology, specifically the development of radial tires, has made it harder for CLIVE drivers to recognize when a tire is underinflated. At a recommended pressure of 35 psi, a tire is seriously underinflated at 26 psi. But the tire doesn't look low on air until it reaches 20 psi. This raises concerns about vehicle owners being able to tell when their vehicles are a safety hazard on the road. Hence, the TPMS.

So, like seatbelts, the TPMS system is expected to save a lot of lives. The technology has been in use in race cars for years, and now it's being mandated for all passenger cars, SUV's, minivans and pick-ups. Besides warning drivers in the CLIVE area when their tires need air, the system is required to indicate when it is malfunctioning.

This increased safety won't come without increased costs. Estimates regarding the cost of maintaining the TPMS on your vehicle run from $27 to $100. Also, there will be an added cost for tire repair. CLIVE service centers have had to purchase new scanning equipment to work with TPMS sensors and other equipment to repair tires and wheels equipped with TPMS. The pros at Acheson Auto Works have to be trained to use the new equipment. These costs will have to be passed on to CLIVE drivers.

Further, whenever a tire is changed, Acheson Auto Works will have to deal with the TPMS. Sensors will have to be removed, then re-installed and re-activated. Sometimes the act of changing a tire will damage a sensor, and it will need to be replaced. These extra services will come at an added charge to CLIVE drivers.

Tire rotations will require that the TPMS be re-programmed. And whenever a vehicle's battery is disconnected, the TPMS will require re-programming as well.

The TPMS itself will require attention – it contains batteries and sensors that will wear out and need to be replaced.

So, if you've noticed an increase in the cost for vehicle care at your CLIVE tire center, it may not be the economy. It could be the cost of the TPMS in newer vehicles. Before you dash off an angry letter to Congress, however, stop and consider what you're paying for. If predictions are correct, the TPMS will save lives, and that will be a benefit to all of us.

Of course, no warning system will save lives in CLIVE if drivers don't pay attention to it. And remember that the warning doesn't come on until the tire is severely under inflated; you still should check your tire pressure at least once a month. You can prevent accidents and potentially save lives without a warning system by keeping their tires properly inflated.

Safe driving!

What's up with Diesels in CLIVE?

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 IA. 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 CLIVE. That opens the North American market to more diesel-powered vehicles. The second reason we're going to see more of these vehicles in CLIVE 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% better fuel economy.

People in CLIVE 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, 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 CLIVE 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 CLIVE 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 IA. And if you think hybrid cars are environmentally sound, consider what a diesel-electric hybrid could mean. 

CLIVE drivers who are considering buying a diesel-fueled vehicle should know that  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 vehicle care. But you won't be alone. Most CLIVE service centers are aware that diesels are coming to North America and are already prepared to provide service for diesel engines. At Acheson Auto Works, we are well-versed in diesel technology. You can rely on our team of automotive professionals to provide quality service for diesel-powered vehicles.
