10.4.9 Drive belt maintenance
The lifespan of the drive belts is affected by belt tension.
■ Slack belts can slip and become damaged and may result in engine overheating.
■ Excessive tension on the belt causes excessive stretch and results in a shorter life span. Over-
tight belts also place unnecessary stress on bearings and shorten their life.
