Hey guys. So...I just replaced the idler and steering pump. The old idler was completely split all the way through. The old steering pump had worn bearings. After I installed the new idler, it would squeal every time I fired it up. Only after the engine had been running for a half hour or so would the squealing somewhat go away. Is this an issue with the belt or the idler??? This was a brand spankin' new idler.

 

I would replace the belt and check the tensioner.

 

What on the tensioner should i check? I mean it is brand new.

 

I thought you only replace the idler pulley.
Definitely replace the belt. Spin all the accessories to check them while the belt is off. Check the new belt is tight. Possible a bad new part...

 

Ok a little update...the squealing only happens when the engine is cold. I ran the truck up and down the road a little and the squealing would get less and less and eventually go away completely after about 15 min.

 

Ok I'll try that. All I know is the old idler was causing no noise.
