I know this sounds really simple but Ive replaced the belt and tensioner recently and just replaced the idler pulley bearing but it still squeaks until the engine warms up and ive been driving for a little while.

Ive seen a couple recommendations on the goodyear gatorback belt to help with squeaks but I was wondering if anyone else has this problem.

None of my other pulleys sound bad by themselves. except for the A/C which has been bypassed for some time now

 

What brand belt are you using currently?

I'm using a Dayco on my Ram and it works just fine. Mine need something with a tad softer compound as it might be too hard in the morning.

 

Not sure Ill have to check. Its not anything special

 

Could b a bearing in water pump or alt, that is going, but not bad, just causing some friction, until it warms up. Try a bit of belt dressing, if it don't help, just keep an eye on things, and c if they get worse, while it's running , at first, can u hear anything around any of the other pulleys?

 

I use a stethoscope. Last time it ended up being water pump. That was on a 5.9 Magnum.

 

I havent been able to pin point where its coming from. Wont have time to do much more trouble shooting for awhile.

How hard is replacing the water pumps on these trucks?

 

Prolly the hardest part is finding a decent water pump.
