My GMC C35 would run for just a while when I start the car. I don't know what's wrong with the engine. It would crank, but the engine won't run continuously. What's the possible explanation for this? I want to have a clue about the possible causes of this unusual car or engine behavior?
This can be an issue related to the spark, compression, or fuel. To find out what the real problem is, first make sure that the fuel tank isn't empty and there's nothing wrong with fuel delivery. Also check if compression is ok or if the spark is actually working. To fix the problem, you have to run an ignition test and have this serviced or fixed right away. If you don't have any clue on how to check the ignition system, then have this checked by your local auto shop or by an ignition service expert.
I messed up this morning. I poured the windshield wiper fluid into the wrong container. The wiper fluid, I'm afraid, has mixed into the brake fluid. What should I do? What's the worst that could happen due to this fluid mix-up?
The braking system has to be flushed (don't just drain the fluid). If you don't flush the system right away and refill it with the fresh brake fluid, some of the wiper fluid can find its way through the calipers, master cylinder, rubber brake hose, and other parts. Because of this, brake failure may happen. For vehicles under warranty, it would be best to consult the dealer first. Discuss the problem to the dealer and see how you can avoid the warranty from becoming void. You may also consider having the vehicle towed to a repair shop or the dealer.
Whenever I check the wheels of the vehicle, the front wheels seem to be dirtier than the wheels on the rear. Why is that? Why are the front wheels collecting more dirt?
It's not just road dirt. It's also brake dust that collects or binds to the wheels. This is because when you apply the brakes, some parts of the brake pad material actually separate or wear off. These turn into dust that you can usually find on the wheel or hubcap. The front wheels gather more dust because the front brakes do much more of the braking; hence, the brake pad material wears off more quickly. For drum style rear brakes, the brake dust actually collects in the drum and goes onto the wheel's backside. That's why the rear wheels may not appear as dirty as the front wheels.
I don't know what to do about the squeak from the door hinges of my vehicle. What is the door hinge squeaking? How can I fix this?
The door hinges squeaks because of friction. To fix this, you need to lubricate the pivoting points. For this, you may add some drops of motor oil. Your options may also include silicone spray, white lithium grease, and products similar to WD-40. To prevent squeaks and door hinge damage, lubricate the hinges at least once a year.
