I want to do a water pump replacement on my 2000 TJ 4.0L.

I hope someone can write a more detail description of the fan belt
removal procedure.

The DC service manual is real vague on how to remove the "accessory
drive belt" (fan belt) especially for the 4.0L engine.

The manual states the following procedure on page 7-32 cooling system:

BELT REPLACEMENT

REMOVAL
Belt tension is adjusted at the power steering pump bracket and idler
pulley assembly.
(1) Disconnect negative battery cable from the battery.
(2) Loosen idler pulley bolt (fig 42). < fig. 42 is of a 2.2L engine >
(3) Loosen tension adjusting bolt (fig 42) and remove accessory drive belt.

INSTALLATION
(1) Check condition of all pulleys
(2) Install new belt. (Caution for correct routing of serpentine belt).
(3) Tighten idler pulley bolt and re-check belt tension. Adjust if
necessary.
-------------------------------------------------------------------------

I'm having trouble finding the tension adjustment bolt at the power
steering pump bracket.

With the manual pictures only showing the procedure for the 2.5L engine
my ignorance of the correct procedure it stalling the project.

I don't see how loosening the idler pulley bolt (it's between the
generator and power steering pump pulley) is going to make the belt
slack for easy remove.

I hope someone can write a more detail description of the fan belt
removal procedure.

 

Hi Brian,
Loosen the idler shaft bolt first, then the adjustment bolt:

I am almost certian you have the same tensioner setup as I have on my
2.5L '98. If so, this is how you loosen the belt to get it off

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.
