5. The next step is the installation of the power steering pump. First remove the belt that connects the
fan and the alternator. To remove the belt, the tensioner lock bolt has to be loosened.
6. Once the belt is removed, loosen the bolts on the water pump connected to the bracket. The support
does not require spacers so it can be bolted with #231880. Leave the bolt loose to make it easier to
install the rest of the bolts and the belt. Insert the bolts one at a time with the two spacers between
the pump and block. The spacer numbers are 205800 and 205810. Spacers will be used one of each
on the bottom bolts part number 231490. Once these are on, install the power steering belt, make
sure to tighten the bolts and belt. The top and middle bolts are the adjustment bolts for belt tension.
7. Once the bolts are all tightened on the pump and belt is in place, the new lines can be installed. The
lines should be installed on the pump first. The return line is the closest to the frame rail; this is just a
slip on fitting with a hose clamp. The blue one is the pressure line, which connects to the fitting on
the pump and is threaded on. Use a wrench to tighten these. Then move to the rack and pinion
ports. The pressure hose with the blue fitting threads onto the upper port and the hose coming from
the reservoir threads lower port, both of which are located on the pinion housing. Pay special
attention to this, accidentally switching these lines will destroy the rack and pinion and will also result
in a voided warranty.
