Help, Loud engine noise!

If you sprayed the belts and the noise no longer existed then I would say it has to do with your belts. They can make a racket if worn or not inline with the pulleys correctly. Have you tried tightening your power steering belt? Are you sure its the correct one?

Just checked the fan and there is a lil amount of play in it, but to be completely honest the belts a the correct size, so id say yes there correct one, but the power steering side v belts seems 3x's more rigid than the alternator side v belt, and yes I have a few times now, I have the Power Steering belt pretty much as tight as I could get it. bout a 1/2 inch of play up and down. If I let it be any less, the belt squeals like a pig with the slightest turn. Now as for the pulley alignment, I dont know how to Correctly check that, by eye it looks good and straight.

After taking a second look at it, when I grab the fan clutch to see if it has any play. I noticed when it moves, it's also moving the water pump pulley... what does that mean? Anyone?

It means you probably found your noise. My truck was making some noises from the front last fall and when I grabbed the fan the water pump pulley was moving. Easy fix.

What would you say I have to replace then? New fan and pulley?

Sounds like a water pump. Tighten the bolt on the fan and pulley and if they are tight and the pulley still moves it's the pump bearing.

Pulled the truck round back at school and found the play in the bearing, new high flow pump and a belt on the way, hah never replace, just upgrade. I'll see what happens.


Thanks for all the help guys!
