Hissing Engine

I doubt your alternator pulley is bad.. Take your belt off and spin each one by hand . Here's a diagram to put it back on(v6) and the Gates part numbers.

 

Wtf? So there are 3 in total?

 

4 idler pulleys, one of them is on the tensioner arm.

 

Miss the good old multiple belts found on older engines

 

So if I want to service would I replace all 4?
Or should I just replace the worn out ones and wait until the rest crap out?

 

Either way.. I would replace all at ones and use the "good" ones as spares if something happens offroading.

 

Sound advice.
Thanks
How difficult/how much time would it be roughly?

 

I had a buddy switch out the idler pulley in the hotel parking lot in 30 minuets so 1 or 1.5 for all since the belt and other crap would already be out of the way

 

Add a little bit more if you have aftermarket skid plates, those things are heavy.

 

True, what helps us is we all carry an electric impact so use it whenever we can.

 

might as well replace the belt too because i don't know when the last time it was changed

 

Mechanic had looked at it and said it was still in good shape

 

Just returning a completely not needed pulley puller rental.
Fuckin done!
Thanks for all the help.
Ended up being the lower 2 bearing pulley but I replaced the upper beside the alternator also. Going to wait till the other ones give trouble before I replace. 2 pulleys and an oil change in an hour. Not bad for my first time.
Now. . . . Anyone know if the tensioner is a different procedure ?
Edit: just saw the tensioner assembly... Can't be taken apart. . . . $188 CAD

 

The tensioner certainly can have just the pulley replaced. I did mine. The diagram I posted has both part numbers.

 

Good shit. Thanks for the correction. I was looking at the diagram at the parts place and the only listed item was the whole assembly. What the difference in terms of install?

 

One bolt vs whatever to take off the whole arm. It's not an exact fit part, but there are others (myself included) that have had success with it. Read more here

 

awesome info ... I read from page 18 to page 28 (last). Seems pulley number one (lower) can be used to replace the tensioner pulley when used without the back spacer.....Right? Good.
Some state to use anti seize on all the bolts and one person states to use thread lock. Should i mix them?
Probably not.
I agree with anti seize but is threadlock necessary?

 

Yes, use the other pulley for the tensioner. That's where I got the number for my diagram. I did not use any antiseize or thread lock, just torqued them.

 

Uhhmmm . . . Why is it only sitting on half the pulley ?

 

You use the right pulley? Some people on the FJ thread had an issue. I did not.
A couple shots of mine. The belt sits towards the edge of the pulley but it's fully on it.
