Squeaking noise at 600 to 700 rpm

[rfanslau]

Hello I have a squeaking noise sounds like the sepertine belt but I changed all the idler pullies, belt tentioner, viscous heater delete kit, and a new sepertine belt the noise only does it at 600 rpm if you raise the rpm to 700 it stops it's driving me up a wall. Could the clutch fan make a squeaking noise like this

Is this a CRD? If so have you checked / replaced the cam belt, water pump and idlers?

It's a crd and no I haven't touched the timing belt, water pump, or those idlers. Does it sound like something in side the timing belt. Should there be more signs besides a little squeaking

No, you don't want any other signs they are expensive! I wouldn't drive it without checking it out, has the belt been done recently?

 

[rfanslau]

No I will have the belt, idlers, & water pump done.

Don't forget it needs HOAT antifreeze, nothing else will do!

Don't discount you might have gotten a bad replacement idler. It happened to me. I picked one up at Advance auto and it also squeaked. I returned it for another one and it's been quiet for two years.

The only thing I haven't changed is the clutch fan I can figure if it's right or left hand thread

Off the top of my head I can't remember, I'll have a look at mine in the morning.

Well with the sepertine belt off the squeaking went away. So new idlers, tentioner, viscous heater delete kit, and sepertine belt, I think I am going to try the clutch fan next. But can not figure right or left thread it's tight

Spin the alternator, the clutch pully is known to squeak. And I would seriously recommend doing the full cam belt change if it's due on miles or time.

 

[rfanslau]

The clutch pully on the alternator is frozen it should

 

[rfanslau]

It should spin freely backwards I was told but will still work and charge. That too was on my replacement list

My plans also are the timing belt and water pump but I first need the get this clutch fan off. It's tight and I dont know if it's left or right hand threads I may be fighting it instead of removing it.
