In the Red (Why a Vehicle Overheats)

Heat is one thing that can damage a vehicle, especially if a problem isn’t taken care of soon.  Be on the lookout for signs that it’s getting too hot in some parts of your vehicle, starting with the most obvious one: the heat gauge/warning light on your instrument panel.

When you see that heat gauge heading into the H zone or the warning light comes on, it’s often because your engine’s coolant is contaminated or running low.  It’s important to let a pro look at it soon before serious damage is done,

The radiator is another trouble spot that can cause overheating.  It has a fan that needs to run properly, and it needs to be free of debris and dirt. Another radiator trouble spot is the core.  When it gets clogged and coolant isn’t circulating as it should, an overheated engine can be the result. Have your cooling system checked regularly, including its thermostat.

Your water pump is another part of the cooling system that can wear out, and when it’s not working right, your engine can get hot quickly.  It should also be on the list of regularly checked engine components.

Finally, your vehicle has several rubber belts and hoses that play vital roles in making sure the coolant is getting where it needs to be.  It’s important to have those inspected by a technician before they fail and heat starts to build up.

Your vehicle’s cooling system is complex and critical to its operation. Plus, it must be maintained so it does what a vehicle’s engineers designed it to do.  When it comes to your vehicle, cool is cool, hot is not.

Budget for Maintenance in Dallas

Sometimes busy Dallas residents dream about going back to the “simpler” days of our grandparents. But if you could travel back in time and take a road trip around TX in a Model T, you might change your mind. The improved designs and quality of today's automobiles have significantly reduced the amount of time Dallas residents spend at the side of the road during breakdowns. With proper maintenance, today's vehicles can stay on the road longer than ever before.

Some of those improvements, however, have led to higher repair costs. For example, older cars often broke down from vapor lock. Gas vaporized while traveling from the gas tank to the fuel pump. No gas, no power. The car quits going. The solution was simple — you just sat by the road until the car would start up again. Today's Dallas drivers would hardly tolerate that kind of inconvenience, and it's likely that yesterday's Dallas drivers didn't care much for it, either. So on today's vehicles, the fuel pump is actually located inside the gas tank. Problem solved. No more vapor lock. The downside is that now it costs a lot more to repair or replace a fuel pump at Dallas area auto service centers.

Dallas drivers certainly should be grateful for the improvements in auto design that keep us off the side of the road, but it comes at a price. Vehicle care in TX  simply costs more than it used to. So if you think about it, Dallas drivers can avoid many vehicle repairs by preventive maintenance. If we plan for maintenance, we can avoid a lot of costly repairs.

Just a bit of auto advice from Dennis Road Automotive: If you like new vehicles and can afford them, then buy them. But if you are buying a new vehicle every few years because you're afraid of the higher repair costs for older vehicles, then you ought to take a second look at the numbers. You can save a lot of money on car payments and TX auto insurance with an older vehicle and preventive auto maintenance can help you avoid most car repair bills. And if you budget for preventive maintenance you have done at Dennis Road Automotive, it can become as routine as a car payment — only a whole lot less!

Ball Joint Replacement

Think about this the next time you’re driving.  Your front wheels can steer your vehicle and, at the same time, the wheels can move, even with all the irregularities in the road moving them up, down and in different directions. Pretty amazing engineering, wouldn’t you say?

What allows that are parts called ball joints.  Most vehicles have them only in the front, but there are some vehicles that have them in the rear as well.  When you consider all the bumps and turns your wheels are subjected to, it’s not hard to imagine the wear and tear these ball joints endure. After any vehicle has put on many months of road time, these ball joints will start to wear out. 

You may find your vehicle’s front wheels clunk when you are on the road, it may not hold the road as well when you go over a bump, or you may feel vibration in your steering wheel and your tires may start to wear unevenly.

When you start to notice any of these symptoms, it’s a good idea to bring it in to have one of our technicians look at what’s going on. If you keep driving with worn out ball joints, you can cause your tires to wear out more quickly.  And if you go even longer, you might find your suspension can collapse, meaning you won’t be able to keep your vehicle under control.  

Many vehicles have upper and lower ball joints, depending on what kind you are driving.  The upper ball joints usually don’t bear any weight while the lower ones do.

When our technician replaces your ball joints, they’ll take your wheels off, then remove the control arm(s).  After replacing the ball joints, they’ll inspect the rest of your suspension to make sure there aren’t any other components that need attention. In some cases, you’ll also need to have your wheels aligned after this service. 

So, when you hear those clunks or feel those vibrations, they may be signs your steering and control over your vehicle aren’t as good as they need to be for dependable, safe driving.  Heed the warning signs and keep your steering and suspension performing the way they’re designed to.

Fuel Injection Keeps Getting Better for Dallas Motorists

Dallas residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.

Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.

Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy for Dallas drivers as well as delivering less power to the engine.

Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice for Dallas residents. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance at Dennis Road Automotive in Dallas. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.
