Pulley or belt

[Mill1978]

Im getting a squeak when the engine get hot and i thinking the belt is bad. What do u guys think?

Visually inspect it, if its dry/cracked pick up a gatorback. Also, I've noticed on our older Buick some belt dressing once a week will quiet it down. I don't know about the effects of it overtime. Also my belt tensioner/idler pulley made horrible screaching when warm as well. Def. get in touch with max (mrzeee on the board) for your oem parts.

Idler pulley. When you take the belt off check and make sure the bearing isnt worn, if it is, replace. easy install.

Take the belt of an spin each component on the belt system by hand... its pretty easy to find something that's bad.

if you want to confirm if its the belt super easy, start the car and hold a small wire brush on the ribbed side of the belt for a few seconds, if the squeek goes away, change the belt, if it doesnt, change the tensioner and idler pulleys together, they are the same pulleys, and get a belt too, might as well right! i get those pulleys at napa for like 13 bucks each.

I have had a new belt still squeak. Go with a gatorback if your replacing it.

screw gatorback, get a gates

 

[BAD97LSC]

ive used gatorbacks and gates, gates are cheaper and seem to last longer, the gatorbacks grip like mad but they dryrot way too fast.

 

[kustomizingkid]

The gates on my Vic squeals on the shift at 1/2 throttle or more... but it is holding up great for 2 years no problem.

I wish they made the gates racing belts for our apps....

 

[bryantaylor]

gates is what most OEM belts are. i refuse the buy anything but a gates

I had a squeak/squeal type noise only when the engine got warm, typically when sitting still.

Turned out it was the electric cooling fan motor. Not sure what prompted it but it was easy to figure out (Just start the car and put it on max a/c 60 degrees. Cooling fan will come on immediately) I opted to replace the whole cooling fan assembly.




The belt and the idler and tensioner pulleys are cheap enough. If you have high(er) mileage it would be good preventative maintenance anyway - so if one is bad I'd replace all 3 (may want to replace tensioner as a complete assembly as they do wear out and loose tension with age. If you see the tensioner wobbling when the a/c compressor is engaged, it's shot)

I went to a gatorback because the gates belt I had on there would squeal back on the 1-2 shift and the new gates belt I put on with the new pulleys started chirping at idle after a month and would slip at high rpm. The gatorback is nice and quiet. It still slips at high rpm but not as bad. I think I will have to try an OEM Ford tensioner.

+ 1

make it easy on yourself..
Get both the idler PULLEY and the tensioner PULLEY {not the tensioner arm}
and the belt.

30 minutes work, no more squeak..and you dont have to worry about it anymore.
