Car Q & A #5 With The Auto Specialist
In the last segment, we helped a driver solve a mysterious problem with his truck’s air conditioning unit. We also responded to a reader’s question regarding the best time to purchase a new vehicle. Those of you who have been following along with this column will remember my plans to address a reader’s noisy tires and an issue with another reader’s power locks. We’re also going to take a quick look at filling your transmission. We have a lot to cover today, so let’s get started.
Question: I bought my car (a Toyota Camry) a couple of months ago. It’s brand new. The tires keep making an awful screeching noise when I’m moving slowly. For example, when I drive in a parking lot and make a turn down one of the aisles, it sounds like I’m leaving rubber on the pavement. Is this normal? Should I be worried?
Answer: I wouldn’t be overly concerned about the screeching noise. It’s common in all vehicles, regardless of how new or old your tires are. However, it’s worth noting that if the pressure in your tires is too low, the screech will be louder than otherwise. So, make sure the pressure is consistent with what your owner’s manual describes.
Question: I’ve having a problem with my car’s power locks. When the engine is running, the locks work fine. I can even use my extra keyless remote to trigger them. But, when I kill the engine, the locks stop responding. Do I need to have them replaced?
Answer: Frankly, it’s difficult to know for certain what the root cause of the problem is without running your car through a couple of tests. That being said, from what you’ve described, I have a hunch that your car’s electrical system is the cause. Understand that the problem may not impact any other parts or systems. But, to be certain, I recommend that you ask your mechanic to take a look.
Question: I know that I should start my SUV’s engine and let it run for a minute before checking the oil. Do I need to do the same thing when I check the transmission fluid level?
Answer: It depends. You’re absolutely right about warming your SUV’s engine prior to checking the oil. With transmission fluid, it will depend upon the type of SUV you’re driving. In most cases, as long as your vehicle is level, a cool engine should be fine. But, check your owner’s manual; it should specifically detail whether you need to start the engine or let it cool down before checking.
That’s it for this installment. Next time, we’ll take a look at another problem with a car’s air conditioner, the value of extended warranties, and what happens when water is used instead of engine oil. Until then, keep your car well-maintained and drive safely.
