![]() ![]() After this it went completely awayĪfter the second day I checked my oil dipstick and it was low so I topped it off with a quart, and now when I check it cold it's on the "high" end of the dipstick.Įver since doing this, I haven't noticed the noise even at a cold start before the car warms up, nor have I noticed any other noises. We explain more about heavy duty belt noise and how to address it in this video: maybe a little lower. The easiest way to correctly diagnose misalignment is to use a laser alignment tool.īy solving the root cause of belt noise, you can address belt noise issues the first time and avoid customer comebacks, and greatly prolong existing and future belt lifespans. The solution: If you hear the belt chirp, address the alignment issues. Components that are out of alignment by as little as one degree can create belt chirp as the belt ribs slide down one side of the pulley grooves. Misalignment: A chirping belt typically indicates an alignment problem between one or more components in the drive. Also, if the belt was contaminated by the leak, it should be replaced as well.Ģ. If a leak is found, repair it, and then inspect the system again to confirm the issue has been addressed. Be sure to also inspect the accessory belt drive system for fluid contamination. Moreover, make sure the correct belt is installed on the vehicle, and that it is not excessively worn by checking it with Gates belt wear gauge tool. If the tensioner is worn, it should be replaced. The solution: The tensioner should always be inspected when there is belt noise. Loss of tension causes the belt to slip, which in turn generates heat that can lead to premature failure of belts, pulleys, and component bearings. This is usually caused by a worn automatic tensioner, but other causes can include a contaminated belt (oil, belt dressing, etc.) or a belt that is too long or worn out. The belt squeals because there is improper tension in the belt drive system. Loss of tension in the drive: This is typically indicated by a squealing belt at engine startup. Our research has shown two main causes of belt noise:ġ. Often, even replacing the belt is a temporary solution, because belt noise is commonly a signal that there’s a problem somewhere else in the accessory belt drive system. So, before you know it, your customer will be back with the same belt noise issues. Not only are these approaches merely quick-fixes that only mask the symptom more than solve the problem, but these contaminants can actually irreparably damage the belt. The most popular misconception is that you can simply treat belts with a chemical or solvent such as belt dressing, soap, brake fluid, silicone spray, or brake cleaner. As an automotive professional, solving this problem can be accomplished, but there are many misconceptions on the proper way to diagnose and address belt noise.
