What is a Balance Shaft Belt?
Your vehicle’s balance shaft reduces engine vibration as you drive. Without working balance shafts, some engines may ruin their motor mounts due to excess vibration.
Your balance shaft belt turns your engine’s balance shaft. Some engines use belts, but others use a chain to drive their balance shafts. Your engine may be equipped with more than one balance shaft. On some vehicles, one balance shaft is belt driven while the other is chain or even gear driven. Your balance shaft belt may run very close to your vehicle’s timing belt as well, making balance shaft belt maintenance even more important.
