Q & A #45 With The Auto Specialist

Author: Car Parts Guy  |  Category: Car Q and A

Welcome back to the Auto Specialist. This past week, I was talking with a few mechanic friends who have been in the business for many years. We traded our favorites stories, including the one about the guy whose brake pads were so worn down that his rotors may as well have been toothpicks. Or, the lady who had accidentally put transmission fluid into her power steering reservoir. These types of mistakes happen more often than you think.

Above all, my friends agreed that fewer people than ever seem to know much about their cars. That’s part of the reason I started this regular column: to offer simple answers to seemingly complex automotive problems.

With that in mind, let’s jump into today’s batch of questions. We’re going to help Josh figure out why his Infiniti’s engine won’t crank. We’ll also answer a question from Marlene about her PT Cruiser’s head gasket.

Question: I own a 2000 Infiniti I30 with the mileage at 113,400. It’s been a great car ever since I bought it new. However, the engine has begun to give me problems (actually, that may or may not be the problem). A few months ago, I was having sporadic trouble cranking the engine. I’d turn the key and nothing would happen. With a few tries, the engine would turn over and everything would then work fine.

The problem is getting worse. Not only does it happen more frequently, but a few times, the engine has even died while I’m driving on the freeway. It just completely turns off. I’ve had the dealership look at it, but they can’t duplicate the issue. Meanwhile, I’m not sure what to do. Any ideas?

Answer: Thanks for your question, Josh. From what you’ve described, I’m going to guess the culprit is the starter. I suggest taking your car back to the mechanic and asking him to run a test on it. If the starter is fine, there’s probably a bad connection somewhere.

Question: I’m driving a 2002 Chrysler PT Cruiser with 68,000 miles. A little more than three years ago, I had the head gasket replaced. I’m not sure what was wrong with it, but my mechanic said it was failing. Ever since then, I’ve had to have the darn thing replaced three times, which is really expensive. I can’t believe this is normal. How often should I need to replace the head gasket?

Answer: Thanks for writing in, Marlene. First, it’s not uncommon for a head gasket to last the life of your vehicle. I’ve seen them last for 200,000 miles. So, replacing it three times in three years should definitely be unnecessary. The head gasket sits between the engine block and cylinder head. Chances are, the surface of one of them (if not both) is uneven. I would ask your mechanic to check the surfaces and smooth them, if necessary.

That’s it for today’s segment. I’d like to thank both Josh and Marlene again for sending in their questions. I know a lot of you have written in with your own questions and are still waiting for me to address them in this column. I will soon. In the next installment, we’ll help Todd with his Mirage’s timing belt and Erin with her Accord’s battery. Until next time, drive safely.

Replacing Your Car’s Drive Belts

Replacing Your Car’s Drive Belts

Most drivers tend to think about their car’s parts in terms of mechanical or electrical components. That is, repairs are usually done to correct problems related to the alternator, intake valve, brakes, catalytic converter, and similar parts. But, your car also has drive belts under the hood. If the belts snap (and over time, belts usually snap), your car will break down. So, it’s important that car owners remember to have their drive belts replaced when they begin to wear. Below, I’ll describe the difference between the belts in older and newer cars, and when you should consider replacing them.

Older Cars Versus New Models

Your car’s drive belts control a lot of other components. There are typically two kinds: V-belts and serpentine belts. When they break, whatever part they control stops working. That can include the air conditioner, alternator, or water pump. When a V-belt breaks, there’s a good chance that your car will break down. When a serpentine belt breaks, your car will definitely break down.

Older cars usually have several belts. Each belt controls a specific part. One might run the air conditioner while another allows the alternator to produce a current. Still another will control the power steering. If one of those belts break, the specific part it’s attached to will no longer function. Newer cars are much different. They usually have one serpentine belt that controls everything. When it breaks, your entire car stops functioning.

How Long Do Drive Belts Last?

Under normal circumstances, a V-belt should last approximately 36,000 miles. A serpentine belt can last up to 50,000 miles. That said, the heat to which the belts are exposed can have a major affect on its life. When there’s a lot of heat generated over time, it can cause the rubber material to harden. When it hardens, it becomes more prone to accelerated wear and cracking. If the belt is loose (you’ll hear a strange screeching sound when you start the car or take sharp turns), the additional friction can add even more heat to the process. So, even though V-belts and serpentine belts are expected to last for 36,000 and 50,000 miles, respectively, you should inspect them before reaching that point.

When To Replace Them

If you look at a drive belt, you may notice small cracks have developed. That doesn’t mean you need to immediately replace the belt. They’re made from very sturdy material. Even with small cracks, they won’t typically break. However, keep in mind that the belts wear over time. Small cracks are one of the visible signs, so you should plan to replace it in the near future. The good news is that it’s easy to identify, and having a replacement installed will prevent your car from leaving you stranded.

5 Quick Tips For Repairing Your Own Car

5 Quick Tips For Repairing Your Own Car

Millions of drivers aspire to repair their own cars. For many smaller repairs, it’s a reasonable goal. Replacing a battery, headlight, or even a fuel filter is a low-maintenance task and can be performed quickly. However, a lot of drivers overestimate their knowledge and abilities. They’ll either try to fix components that are too complex without the proper tools, or they’ll hurt themselves. For those people who are devoted to the idea of doing their own car repairs, I’ll give you 5 quick tips for safely getting the job done.

Tip #1: Know The Part’s Weight

A lot of parts are heavy and can cause injury if you’re not prepared. For example, changing a tire is a simple process. But, if you suffer from chronic back pain, it’s a bad idea. The same goes for pulling out a cylinder head. Reading the instructions in a manual isn’t the same as actually lifting the head.

Tip #2: Know The Part’s Complexity

Twenty years ago, you could lift your car’s hood, identify the problem and fix it without a mechanic’s help. Today, cars are designed with components that are increasingly complex. Some of them require special diagnostic tools to figure out if there’s a problem. Before digging under the hood, understand how complex the issue is.

Tip #3: Use Sturdy Support

Each year, people place their cars on wooden blocks, bricks, and even chairs before crawling underneath to perform repairs. Accidents happen often. If you must crawl under your car, you need to use strong jack stands. They’re designed specifically to withstand the weight of your vehicle. When placing the jack stands, make sure you secure them to a part of your car that won’t crush under the pressure.

Tip #4: Unhook The Battery

If you’re trying to repair an electrical component (i.e. starter, wiring, etc.), unhook one of the cables attached to your battery. You might be surprised by the damage you can cause by crossing the wrong wires.

Tip #5: Eliminate Loose Ends

Don’t wear anything that can potentially become caught in the car’s parts. If your clothing, jewelry, or hair gets wrapped into a fan, pulley, or other component, the results can be disastrous. Tie your hair back, wear a t-shirt, and take your jewelry off before looking under the hood.

Safe Home Auto Repair

Accidents happen during car repairs because of negligence, over-confidence, or lack of preparation. In short, a lot of people underestimate the nature of the job. It’s important to realize that many types of repair work should be done by a trained technician. Car parts are far more complex today and often require special tools. That said, if you’re planning to work on your car at home, use the tips described above to do so safely.
