Hey folks long time no see!

Here is my problem. I have a pulley squealing. From what I can tell it is the top most pulley on the engine. My problem is I don't know what it is. LOL sad for me. Can someone tell me if I am right in thinking it is the idler pulley? I'm kind of a n00b when it comes to this.

Should I replace any others while I am there? I'm already going to get a new belt. 8 year old parts isn't so bad. Especially since its been squealing since I have owned the truck since it was brand new. Funny thing is my mom put soap from a soap bar on the belt and it stopped squealing in park and squeals when its in drive now.

Thanks for the help in advance.

 

so what you're saying is... your mom fixed your truck for you.

just kidding man.

 

At first I thought so LOL, but now it squeals no matter what.

 

***Update** So here is what I think I need,

Idler pulley
tensioner pulley
Belt

Im assuming those two pulleys are two different ones? Whats the difference between the serpentine and v-rib belts?

According to ummit I need a belt that is 85.50 in, is that right?

I have gotten into the habbit of checking thing and hen rechecking them again.
