Why is my brake so noisy? I cannot focus on driving because it is so annoying.
Well, the common cause of a noisy or squeaky brake is a worn-out brake pad. You have to check it regularly and have it replaced if needed. However, there are other factors that can cause your brake to squeak. These include rusty brake rotors, which can happen overnight due to moisture, and stepping on the brake pads too hard, causing heat that can glaze brake pads and produce annoying squeaky sounds. Go to your nearest repair shop to have your brake pads checked and replaced if necessary.
It is my first time to experience engine overheating with my GMC G25. What should I need to do?
There might be some problem with your cooling system. Make sure to monitor your temperature gauge while driving. If the temperature hits "H" or hot and you see steam coming out from your GMC G25's hood, you have to carefully park your car on a safe place and turn the engine off to let it cool. Let the temperature go down by opening the hood. Carefully add water or coolant to the reservoir. But if you are not familiar with the parts, better go to the nearest mechanic to provide you an intelligent solution.
I think my fuel gauge is faulty because I notice that it is not providing accurate fuel reading. What seems to be the problem?
The first thing you need to check is the fuse. Worn-out fuse is one of the main reasons behind faulty fuel gauge. Replace your old fuse and check if the fuel gauge starts working properly. If not, you have to inspect the voltage limiter if it's in good condition. Fixing your voltage limiter will also fix your fuel gauge problem. Sometimes, corroded wirings are also the cause of a faulty fuel gauge. It might be hard to locate and to troubleshoot, so ask help from a qualified mechanic instead.
What are the signs of a failing alternator? I am worried that my GMC G25's alternator would fail.
The purpose of the alternator is to provide power to all of the electronic parts of your car. So when you notice that your battery is so weak, try charging and then check if it's still weak when starting your engine. If so, the alternator is really the problem here. You also need to check the alternator alone if it is working properly. If not, ask a mechanic to double check the errors and replace it if needed. If it seems that the dim lights or lights in the dashboard suddenly fade away, it is already a sign of a faulty alternator. Always be cautious and careful. Regular inspection is the key to maximize your vehicle. Watch out for foul smell as well because it might be a sign that the system belts had overheat. This will lead to a rubber that is slipping on the alternator pulley, resulting in poor alternator performance.
