Squeaky belt
1 Attachment(s)
Every time I start my truck I get a nasty squeak from the belt, (Drives me nuts.) After initial start up it may or may not squeak. This never happened before until I got stuck in a nasty mud hole. (Unfortunately I had to abandon it overnight until I could get it out.) I have cleaned the engine bay and inspected all the pulleys and components which seem fine, I have sprayed the belts down with belt dressing. I have replaced my belts within in the past 30,000 miles prior. You can definitely tell I like to play outdoors by looking at the belts but, never had this issue before. Should I just replace my belts or are there other things i should look into. Just wondering because I love my Toyota... Any input would be greatly appreciated. My guess is probably just be new belts. But wanted further input or ideas. Thanks..
(By the way the bighorns suck in clay and do not clear out Which was the bottom of the pit.) For those wondering here is a pic.. I got stuck mainly because of my trailer hitch dragging the mud and open diffs.. Other than that the vehicle did good.) |
it could be just the brand of belts to

usually the squeak is the alternator if the alt belt is slipping the alt will squeal, check your belt tension, could be a little loose. i changed my alt and after i put it back on my belt squeald cuz i didint pull it tight enough
|
yeh but not too tight on the alt belt. It gotta be just goldy locks tight.

x2 on the alternator belt...The alternator is under heavy load at start-up. I've also had this issue and found that non-Toyota belts do not hold tension as well as OEM belts. After a month or so of installing new belts, I began having the squeal at startup (mostly after a rain or snow shower). I battled this for about a year (continually re-tightening the alt belt) until I had my timing belt changed, and I had them install Toyota belts. That was about 6 months ago...so far so good.

dirt and water make it slip, and that will go away
OR, it may slip and get glazed. then the squeak will never go away new belts are needed if they get glazed. you can try buffing them with 100 grit but I have no idea if it will work or if I am talking out my butt |
Thanks for the reply's, the belts are factory Toyota. I will try adjusting the alt. Thanks again...

I changed my belts last night and tightened everything up...am I correct to see only 1 bolt (on top) on the alternator that makes it pivot? I've tightened mine up, but still squealling on start ups.

That is correct. How tight is the ALT belt. About 1/4" deflection should be good. Before changing your belts, did you give the pulley(s) a good lookover to check for rust, etc.? If not, that may be the problem. Take a brass, not steel, brush to them for cleaning. |

My belts squeak sometimes, but that's only after it rains. They can get a little wet since I have the sport scoop.
Also, this is pretty cool.
