Engine Hydration for Rowlett Drivers: Role of Your Water PumpJuly 18, 2021

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 Lewis Complete Auto Repair 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 Rowlett residents to replace both of these parts whenever either one needs it.

Replacing a water pump at Lewis Complete Auto Repair is a vehicle care issue that almost all of us Rowlett 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.

Don’t Do It Yourself (Perils of DIY Vehicle Repair)July 11, 2021

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn’t too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies. 

Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn’t see a lot of until as recently as the 1990s.

Today’s most highly-trained technicians are able to keep up with how to perform the latest repairs and service by continuing education about their craft.  When once an auto repairman could do fine with a lift and a good set of tools, now specialized electronic analysis equipment and tools are must-haves when it comes to vehicle repair.

Because of how fast technology changes, access to the latest repair databases and manuals is also important.  Manufacturers require certain service procedures to be performed precisely, and any other way can leave a vehicle compromised when it comes to performance and safety. 

Your vehicle is capable of traveling at high speeds on challenging surfaces with ever-increasing traffic issues and unpredictable obstacles.  You need your vehicle to be working up to its engineered potential.  That’s why you should leave repairs and service to professionals.  They work on vehicles every day, and years of experience with hundreds of repairs equip them to deal with the unexpected as well as the routine. 

When you develop a trusting relationship with a reputable service facility, you can have confidence that the maintenance, service and repairs are being done by people who know what they’re doing.  Your safety and your vehicle’s performance and reliability are well worth it.

Such a Little Part (Climate Control Resistor)June 27, 2021

You expect your heater/air conditioner to work like it should.  You have a control for temperature and one for fan speed.  You even have a control for what vents the air comes out of. 

Don’t be surprised one day if your blower fan develops a mind of its own and starts going crazy.  Most of the time, you may find that it starts blowing at full speed, and nothing you do to try to control it does any good.  This is what may be happening.

Your blower motor has an electronic component called a resistor.  It does what its name says; it offers resistance.  When you want the fan to run more slowly, you turn the fan speed down.  That resistor accomplishes that by turning its resistance up.  When the resistor fails, the power has nothing to slow it and the fan speeds up. 

It’s a small part and can fail due to age or corrosion.  It’s usually not an expensive part, either, but it’s often found in a location that’s not that easy for the technician to get to.  That means labor costs will vary depending on the design of your vehicle. 

Occasionally, a faulty resistor can cause the blower motor not to work at all or only partially come on.  But other things can cause that as well, such as a faulty fan switch or vent control. 

This is where a technician’s training comes in.  Special equipment can track down precisely where the issue is so you can be assured the correct part is being replaced.

It’s just not pleasant when the blower motor isn’t following orders.  Have your service facility check it out so you can be the blower’s boss, like it should be.

Wired! (Battery Cable Service)June 20, 2021

Colder weather brings out the worst in a vehicle’s battery.  On a very cold day, you may have experienced that your engine cranks slowly when starting.  But while it may be the battery itself, it may also be the parts that transfer the power to other the other electrical components, the battery cables.  After all, you have to have some way to get the current out of the battery and out to where it needs to go.

Battery cables have a couple of enemies: corrosion and age.  You may have looked under the hood and noticed a light-colored powder or crust around the terminals.  That’s what happens when acids corrode the ends of the battery terminals.  Corrosion inhibits the connection and may reduce the amount of power getting to the electrical accessories to the point where they are not working correctly, if at all.

Here are some symptoms of problems with your battery cables. You might notice a clicking sound when you turn the key, some of your vehicle’s electrical parts (like the sound system or the horn) don’t work or, in some cases, the vehicle won’t start at all.

When you take your vehicle to a repair facility, the technician will use instruments to check voltages to see how much current is getting to what location. That includes a starter draw test during which the battery’s voltage is checked when the starter is cranked.  The technician will also visually inspect the cables and the charging system. To make sure the alternator is putting out the right voltage, the technician will measure that as well. 

If the problem is found to be the battery cable assembly, the entire set may have to be replaced. Sometimes they can be repaired. 

During the colder months, it’s vital that your vehicle has the proper power going to its electrical components.  Having a vehicle that won’t start or run smoothly is not something you want to battle with when you’re already up against challenging weather.  Keep your electrons flowing… and your vehicle moving.
