When to Replace Car Engine Drive Belts

Knowing when to replace drive belts in a car can end up saving you both time and money. These belts are typically not difficult to replace, depending on your particular car. It is a fact that the belts will need to be replacing eventually, and it is much easier to replace them at your own convenience than when you are out on a road trip and miles from the nearest service station.

• Check the drive belts periodically for wear and tear. It is a good idea to check the belts when you change your oil. If the belts are looking cracked or appear to be worn in certain areas, you will want replace them soon. Otherwise, continue checking the belts for wear and tear at least every 6 months, or every 5,000 miles. Be sure to check your car owner’s manual to see if there is any important information that pertains to your specific make and model of vehicle.


• Listen for any new noises especially for any persistent grinding or squealing sounds that begin when you turn the steering wheel, or turn on the air conditioner. These sounds can result from a torn belt, or a belt that has been installed too loosely. Other issues caused by a torn belt could cause failure with the power steering, water pump and brakes. A completely shredded belt will likely cause a complete breakdown of your vehicle.


• Replace any worn or ripped belts and re-check the belts after the first 500 miles. This will ensure that there is not any abnormal wear on the belt, and that it isn't installed too tightly or too loosely. If the belt is not properly installed, the pulleys that hold the belt in place can become bent or damaged which will put excessive stress on the belt, and prevent them from working properly.
