Review on πŸ”§ Efficient and Reliable: ACDelco 38001 Professional Idler Pulley for Increased Performance by David Caldwell

Revainrating 5 out of 5

Why did you replace the alternator and not the tensioner?

When I replaced the alternator on my '97 Chevy truck, I also replaced this part (belt tensioner). This part isn't expensive, so it makes sense. The one I replaced ran like it had little pebbles in the bearings - obviously it wasn't going to last long. Be smart and do it.

Pros
  • Absolutely amazing!
Cons
  • I won't say anything
