REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Disconnect the negative battery cable.
- Remove some power steering fluid from the reservoir by disconnecting the fluid return line hose at the reservoir. Drain the fluid into a container and discard it.
- Remove the pressure hose from the pump. If equipped, disconnect the power steering pump pressure switch.
- On the 2.3L, 2.5L and 3.0L engines, loosen the idler pulley assembly pivot and adjusting bolts to slacken the belt tension.
- On the 2.9L engine loosen the adjusting nut and the slider bolts on the pump support to slacken belt tension.
- On the 4.0L engine, slacken belt tension by lifting the tensioner pulley in a clockwise direction. Remove the drive belt from under the tensioner pulley and slowly lower the pulley to its stop.
- Remove the drive belt from the pulley. If necessary, remove the oil dipstick tube.
- If equipped, remove the power steering pump bracket support brace.
- Install power steering pump pulley removal tool T69L-10300-B or equivalent. Hold the pump and rotate the tool counterclockwise to remove the pulley. Do not apply in and out pressure to the pump shaft, as internal pump damage will occur.
- Remove the power steering retaining bolts. Remove the power steering pump from the vehicle.
- Position the pump on the bracket. Install and tighten the retaining bolts.
- Install the pulley removal tool and install the power steering pump pulley to the power steering pump.
Fore and aft location of the pulley on the power steering pump shaft is critical. Incorrect belt alignment may cause belt squeal or chirp. Be sure that the pull off groove on the pulley is facing front and flush with the end of the shaft ± 0.010 in. (0.25mm).
- Continue the installation in the reverse order of the removal procedure. Adjust the belt tension to specification.
- On the 2.3L, 2.5L and 3.0L engines torque the idler pivot pulley bolts 30-40 ft. lbs. for the 2.3L, 2.5L engine and 35-47 ft. lbs. for the 3.0L engine
- On the 2.9L engine torque the slider bolts to 35-47 ft. lbs.
- On the 4.0L while lifting the tensioner pulley in a clockwise direction, slide the belt under the tensioner pulley and lower the pulley to the belt.
- Disconnect the coil wire.
- Crank the engine and continue adding fluid until the level stabilizes.
- Continue to crank the engine and rotate the steering wheel about 30° to either side of center.
- Check the fluid level and add as required.
- Connect the coil wire and start the engine. Allow it to run for several minutes.
- Rotate the steering wheel from stop to stop.
- Shut of the engine and check the fluid level. Add fluid as necessary.
QUICK-CONNECT PRESSURE LINE
See Figure 4
If a leak occurs between the tubing and the tube nut, replace the hose assembly. If a leak occurs between the tube nut and the pump outlet replace the plastic washer.
- Check the fitting to determine whether the leak is between the tube and tube nut or between the tube nut and pump outlet.
- If the leak is between the tube nut and pump outlet check to be sure the nut is tightened to 30-40 ft. lbs. Do not overtighten this nut.
- If the leak continues or if the leak is between the tube and tube nut, remove the line.
- Unscrew the tube nut and inspect the plastic seal washer. Replace the plastic seal washer when the line is removed.
- To aid in the assembly of the new plastic seal washer, a tapered shaft may be required to stretch the washer so that it may be slipped over the tube nut threads.
- If the rubber O-ring is damaged it cannot be serviced and the hose assembly will have to be replaced.
- Connect the tube nut and torque to 30-40 ft. lbs.
