Engine Hydration for Tucson Drivers: Role of Your Water Pump

Posted: Mar 17, 2019

The cooling system in an engine has five components: the radiator, the radiator cap, the hoses, the thermostat and the water pump. The water is literally the heart of the system. Just as your own heart keeps your blood circulating through your body, the water pump keeps coolant circulating through your engine.

The water pump is driven by a belt, chain or gear and only operates while the engine is running. It has a limited life span and sooner or later will have to be replaced. You can check your owner's manual to find out how long your water pump should last. Some can fail at only 40,000 miles (64,000 kilometers), but almost all of them fail by 100,000 miles (160,000 kilometers).

Water pumps don't gradually wear out; they fail. In other words, they're either working or they're not. A failed water pump has to be replaced.

Water pumps can fail in two ways: they can spring a leak or their bearings fail. Leaks can come from a cracked pump but usually develop at the gasket where the pump attaches to the engine.

If you hear a low-pitched grinding sound coming from the water pump, it's time for a new one. If you see coolant leaking in the area near the pump, it needs to be replaced. Also, coolant on the driveway could indicate water pump failure. Many water pumps aren't visible because they're under a plastic cover, so you may have to take your vehicle to Advantage Auto Repair & Transmisson to know if the water pump has failed. If your water pump is run by the timing belt, then it should be replaced when you replace the belt. Most timing belts need to be replaced at around 60,000 to 90,000 miles (100,000 to 150,000 kilometers). The labor for replacing a timing belt is about 90% the same for replacing a water pump, so it's cost-effective to take care of them both at the same time. Also, if your water pump develops a leak (if it's powered by the timing belt), you have to replace the timing belt as well since contamination by coolant fluid damages the belt. It just makes sense for Tucson residents to replace both of these parts whenever either one needs it.

Replacing a water pump at Advantage Auto Repair & Transmisson is a vehicle care issue that almost all of us Tucson residents face eventually. They don't last forever. On the other hand, we can extend the life of most of the components of our vehicle through preventive maintenance. Just as exercise and diet keep our heart healthy, regular check-ups and fluid changes will keep our vehicles healthy. Talk to your friendly and knowledgeable Advantage Auto Repair & Transmisson service advisor.

Fuel Injection Basics for Tucson

Posted: Mar 10, 2019



All modern Tucson vehicles come with fuel injection systems, so it's a topic Tucson 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 timeto 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 Tucson, 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.

Advantage Auto Repair & Transmisson can help Tucson 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 Tucson with fuel prices as high as they are, but major brands in the Tucson, 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 Tucson 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 Tucson, 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 Advantage Auto Repair & Transmisson in Tucson. But putting the cleaner in the fuel tank after you've had Advantage Auto Repair & Transmisson 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.

Coolant Service at Advantage Auto Repair & Transmisson

Posted: Mar 03, 2019

Tucson residents' vehicles have to operate in a wide range of AZ temperatures which requires the engine coolant to be able to perform 'no matter what.' Think for a moment about the environment where the coolant does its thing. Very hot, high pressure, corrosive...

And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That's why vehicle manufacturer’s recommend different types of anti-freeze for our Tucson, AZ, vehicles.

There are several different 'families' of anti-freeze available to us here in Tucson. Your owner's manual will tell you what kind you should use. Of course, the automotive professionals at Advantage Auto Repair & Transmisson will know the right kind for your vehicle.

It's important to stay on top of this because coolant system failure is the most common mechanical problem people have here in Tucson, AZ. Regular service needs to be done at Advantage Auto Repair & Transmisson to avoid failures and also to keep your warranty in place.

While the specifics of the service required may vary from vehicle to vehicle, your friendly and knowledgeable Advantage Auto Repair & Transmisson service advisor will know what to do. You'll be advised to replace the coolant at specified intervals.

Some recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your owner’s manual recommends.
