You may not know your serpentine belt needs to be replaced, but there will be signs! In this video, Len takes you on a tour of the front of the engine to look at not only the serpentine belt, but all the pullies, pumps, and compressors that the belt drives! You'll find out how to tell if the belt is in need of replacing, and also what to look for with other components that might be near their end as well! #serpentinebelt #autoparts #enginerepair | 1A Auto Parts
