packjh Posted May 29, 2007 Report Share Posted May 29, 2007 Ever since i changed my cam i had a squeaky belt. I changed that out and it was alot better. The only thing is when it starts up i have a squeak on a cold motor. Sometimes it will squeak the whole time driving other times it will stop and i can hear it at about 1500 rpms and higher if my exhaust didnt drown it out. I cant hear it at idle. Sounds more like a pulley is squeaking tho. Any ideas. I thought about getting a gator back belt, or changing out my tensioner?? Quote Link to comment Share on other sites More sharing options...
pnblwzd Posted May 30, 2007 Report Share Posted May 30, 2007 I noticed a strange belt slipping noise after doing my cam swap also, but it went away after a few days. Never had a long squeel though, just an occasional chirp. Maybe the belt(s) or pulleies got some coolant or oil somewhere and it took that long to dry...?

BenKey Posted May 30, 2007 Report Share Posted May 30, 2007 How many miles do you have on your truck? My alternator had a bearing going bad in my last truck at just 40k miles. Not that that is it, but could be. How many miles ago was the cam swap? Did you do or someone else? Quote Link to comment Share on other sites More sharing options...
packjh Posted May 30, 2007 Author Report Share Posted May 30, 2007 I did the cam swap, and its just an occasional chirp. I did the swap about 1200 miles ago, considering it took 1000 this weekend driving to palmer and back and traveling around anchorage. I have lil over 28k on the truck now. I did notice that if i sping the alternator pulley it chirps you think that might be the problem?? Its just a chirp like half to full second.

If you can spin your alt pulley without the belt on it and it is making noise, then that is what I would diagnose it as. It is not uncommon for the bearing to go out in them. Maybe not the usual cause for noises, but it is one of them at least. Quote Link to comment Share on other sites More sharing options...
packjh Posted May 31, 2007 Author Report Share Posted May 31, 2007 thanx ben i just posted the same thing in video section where i had a sound clip of it but woody told me to squirt wd40 in it and see if it stops well it did immediatly for a few seconds so that was definitely the problem. Dont wanna pay more money but you gotta pay to play Quote Link to comment Share on other sites More sharing options...
