It is hotter or very cold outside than the sun, and these pulleys seized the decision.Either way, you will be at the mercy of external factors until help comes.Here are some tips that will help prevent stranding along the road, because either the serpentine belt tensioner bearing is broken or stuck. ? There used to be at least 50,000 miles of serpentine belts, if not more.Check Pulley, Check the operation of the thin belts along the ribs, if they break, it’s time to replace the belts.Check Pulley Edge, see if there is abrasion on the edge.The side around the pulley will eventually tear and may cause major problems.Most vehicles today have two snake-shaped belts.

This is not always the case.The bearing can jam without any warning signs.To check the pulley, make sure the engine is turned off.Loosen the serpentine belt and a tension wheel appears.Turn the pulley manually, there is a sound from the bearing, listen carefully.The pulley should rotate freely without any resistance.The bearing should not be noisy.If the wheel sounds dry or rough, it is time to replace the tensioner assembly.This is a good idea to check the serpentine of each service interval bandWhat is required is a visual inspection, which involves very little time.
