Installed an Autozone 92-2797 fan clutch last night. Seems to work ok
with the testing I could do. Only 83° but I have a nice, steep test
hill. It got fully engaged a few times.
The problem is that when it does engage the belts start squealing like
crazy. Backing off the gas a bit makes the squeal stop but that doesn't
work well when climbing a big hill.
Noticed this the few times the old clutch would engage on my last trip, too.
I'm thinking I need a dual alternator pulley and belts but if it's the
fan clutch making the belts squeal then it's not an Alternator problem.
It's the water pump pulley that is squealing, no? And that already HAS
two belts on it.
Time for new belts? They might have 10,000 miles on them. Maybe 6
years old. Didn't keep good records of when I replaced them last.
Still look to be in great shape.
What say ye?!
