Review on ACDelco Professional Serpentine Drive Belt Tensioner Kit - ACK040378HD by Ken Hamdan

This is an AC Delco who normally supply quality parts. My old one got wet when my water pump exploded and the stretcher was right under it so he started yelling everywhere I went. This part helped and my Tahoe 5.3 from 2003 is back to normal. Just two screws. You have to undo the serpentine strap to change the accessory strap, which is very easy after I removed the fan cover and lower fender. You can probably change it without taking them off, but I hate working in small spaces.
