How do can I remove the fan belt from 2000 TJ 4.0L

I am almost certian you have the same tensioner setup as I have on my

On the PS pump bracket, there is in idler pulley. Sticking out of the back of the idler pulley is a bolt, perpendicular to the axel of the pulley, this bolt adjusts the tension. This bolt is parallel to a channel in the idler pulley bracket that the pulley moves up and down on to adjust the tension.

First, loosen the bolt in the middle of the pulley, then turn the tension bolt (CCW I think) until the belt is loose enough to slip off. To put the belt back on, first tighten up the tensioner bolt, then tighten the axel bolt to clamp the pulley in place.

Which year FSM do you have? The 2000 model year saw a spring-loaded idler pulley/arm which maintained the belt tension, not the old power-steering pump adjustment. It should be located just below the alternator. I had to remove mine to install the Kilby air compressor.

Yes Bill, in 2000 the tensioner was introduced, I know because I had to remove mine to install the Kilby. The tensioner assembly is still sitting in my garage. If memory serves, you use a wrench to rotate the tension arm enough to remove the belt. Hey, just like the instructions say, go figure. Brian, look at Bill's pdf, but be sure to look at the 4.0L page, not the

Just had mine off my 2000 this weekend. It uses a spring loaded tensioner arm/pulley located on the right front under the alt. (left side as viewed from the front) Insert a 1/2 inch ratchet or breaker bar in the square hole on the arm and rotate to remove tension from the belt and while holding it, slip the belt off the power steering pump. Let me know if you need more info

That's interesting, Bill, but of course we're not talking about a Ford engine... :-)

Actually it's not exactly the same, as the alternator on the Triton is directly above the water pump, between the cyl heads, and on the 4.0L the tensioner doubles as the alternator mount. The Triton tensioner is on the passenger side, at least.

But it's still irrelevant since the OP has the Jeep 4.0L engine, not a Ford.

The Triton engine compartment is a little too high and tight to try to take the belt off just for you, Bill. :-) Besides, it's getting cold out there.

I can't take the belt off by hand on the TJ anymore. Have to loosen the air compressor bolts and slide it toward the valve cover a bit.

When I took the belt off to install the Kilby (only time I needed to take the belt off up to that point) I was able to easily pull it off. Don't recall if I used a tool to loosen the tensioner or did it by hand.

Thank you. With Mr. Hughes .pdf manual diagram (My DC year 2000 $100 manual does not show the diagram of the spring loaded belt tensioner) and your info on what tool to use and where to use it is just the information I needed to begin the water pump replacement job.

Brian, look at page 7-31 of your manual. It has the belt routing schematic on that page, though it does not have the diagram found on Bill H's illegally ripped pdf pages. :-)
