This is a strange one to me. Here is the summary:
2003 Chevy Tracker (same as Suzuki Gran Vitara) v6 2.5L
For about a year, it has had belt squeal on starting, which lasts about 5 minutes…it’s louder when AC was on…would go away with higher RPMs. Once the car was warmed though, no squeal.
A\c has been working very well and blowing cold whole time. Finally it around to replacing belt, which was a huge pain.
Tightened with an idler pulley type system(not spring loaded). Started it up, squealed a little on start, but went away…turned on AC and the squeal is horribly loud now and constant…high rpms only make it louder. Noticed that clutch engages fine, but spins inconsistently…like we’ll the belt is slipping. It spins slow, fast, slow…etc. I can’t tighten anymore as the tightening bolt is at the end of the channel, don’t want to strip it. Also noted that it is about a bolt head width more tight than its previous position.
Surely changing the belt wouldn’t cause the clutch to bite it would it?
Other notes…drives great when ac is not on. This is an acc only belt…ac,idler,power steering. Also, during the repair, antifreeze got on the pulleys…I cleaned them all around with generous spray of brake cleaner…they look clean.
Any suggestions? I’m going to try to loosen it tomorrow to see if that is an issues, but seems far fetched.
