The roar of an engine or the humming of a moving vehicle are good sounds to hear. However, there may be times when strange noises from your vehicle are trying to tell you that you need to have your Toyota car parts serviced. Sometimes that weird noise may be a rock stuck under the hood, but sometimes it really does mean a problem that can be potentially hazardous if you do not attend to it. Learn how to listen to your vehicle and identify strange noises.
Under the Hood Sounds
Strange noises from under the hood can mean a few things. You first need to distinguish the type of noise you hear such as a squeaking or a hissing. A squeaking sound can mean that there is some damage to your accessory belt. Accessory belts can be worn or damaged when they slip and this damage causes the belt to lose traction. You should have a professional look at the accessory belt to see if there is shiny or glazed.
You should also listen for hissing under your hood. If you hear a hissing while the car is idling, the vacuum line may be damaged. The hissing occurs because of a vacuum leak, which becomes clearer when the car is idling. The good news is you may only need to have your vacuum line reattached. Even if you do not hear the hissing, have the mechanic check to see if the line is loose if you keep seeing the "check engine" light appear.
Grinding can be one of the scarier noises from a car. It is also one of the most dangerous sounds because this is usually the brakes grinding together. Brake pads wear away and need to be replaced every so often. If they continue to wear down, the padding wears away completely and leaves only metal grinding against metal, which produces the harsh grinding sound. In addition to causing damage to the brakes, the grinding can also damage the brake rotors.
Squealing can also mean there is a problem with the brakes. However, squealing usually comes from the wheels. The squeal is not as harsh a sound as grinding, but it is very disturbing and often leads to the grinding if the brake pads are not repaired or replaced. You should also find out if you have drum breaks because a squealing with these kinds of brakes can mean that the brake linings are worn or glazed.
Under the Vehicle
Rumbling noises under the vehicle can able mean a number of things from a damaged exhaust pipe to a worn universal joint. Defective mufflers or catalytic converters may also cause a rumbling. If you hear a clunking under the vehicle, particularly when you drive over bumps, have a professional check the shock absorbers and suspension system. The problem may also be as simple as a loose tailpipe or muffler. A loud abnormal sound can be a hole in the muffler, which will need to be replaced.
