hey guys, as some of yall know i just rebuilt the 4.0 in my 91'..... the water temp gauge in the dash works but does not get up anywhere near where it should, but it did before. i've tried 2 different sender's and same results with each. i'm not sure if the engine is not warming up or if the gauge is reading wrong. any way to check?
second, it squeaks like hell when running. its clearly one of the front end components, it follows the rpm curve as well ( faster it revs faster / louder the squeak) i tightened the belt up a good bit and that helped a tad. sounds like its from the water pump. but if i put soap or spray wd40 on the belt itself, the noise goes away until that wears off. so i dont THINK its an actual pulley or internal component. should i just tighten it up some more and see?
Sounds like something is out of alignment or adjustment which is causing the belt extra surface touching and causing it to squeek. Do you have air conditioning?? What i did is i took took out the stock temp gauage and put a mechanical one and made it fit in the stock location with some glue and sheet metal. I love it
And don't put wd40 on your belt, it just makes it slip. You may just have a slippage problem and the wd40 helped it slip 'better', thus lubricating where it's slipping from. I would take your belt off and degrease it and all the pullies. Break cleaner makes this fast, or you can use simple green and spray it off. I've had this problem before. After i got all the foreign lubes off of it, it gripped nicely and is still running strong.

i think i've figured out my temp problem.... when i installed the t-stat and housing, the gasket had an adhesive side that went to the block. i put the gasket on, then the t-stat, then the housing. the t-stat basically cut out the gasket around it. i guess letting water by, ( it was also leaking at the t-stat). so i'm assuming that i should put the t-stat in the block, then sandwich the gasket btwn the t-stat and the housing?
still not sure what the squeak is. took the fan off, squeak still present. tightened the belt up (a lot) still squeaking. next i guess is i'll have to check each pulley. but not sure how to do that other than pull each one off and drive it with a drill somehow? any ideas
