REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
All LH platform vehicles with all available engine options use the Saginaw T/C style power steering pump with a remote mounted reservoir for the power steering fluid. The fluid reservoir is mounted to the left frame rail of the vehicle just rearward on the battery tray. No repair procedures are to be done on the internal components of the Saginaw power steering pumps. Repair of power steering fluid leaks from areas of the power steering pump sealed by O-rings is allowed. However, power steering pump shaft seal leakage will require replacement of the power steering pump.
Use only Mopar Power Steering Fluid or equivalent. DO NOT USE ANY TYPE OF AUTOMATIC TRANSMISSION FLUID. Fluid level should be checked with the engine OFF to prevent injury from moving parts. Do not overfill. The dipstick should indicate FULL COLD when fluid is at outside air temperature of 70° to 80°F. Use care to make sure all power steering fluid hoses are returned to their original locations and positions. Clearance for most of these components is very close. Observe the way the hoses are positioned before removal to avoid chaffing damage later.
- Disconnect negative battery cable and isolate from the battery.
- Loosen the power steering drive belt by loosening the generator mounting pivot bolts and turning the adjuster bolt or loosen the power steering drive belt by loosening the adjuster pulley locking nut and then loosening the adjuster bolt. Remove the drive belt from the pump pulley.
- Raise and safely support the vehicle.
- Position an oil drain pan under the vehicle to catch leaking power steering fluid. Remove the hose clamps from the power steering fluid inlet hose at the pump. Remove the hose at the pump.
- Loosen and remove the power steering pressure hose from the power steering pump discharge fitting.
- Loosen and remove the 3 bolts attaching the pump to the power steering pump mounting bracket. Access to the pump mounting bolts is through the holes in the pump pulley.
- Remove the power steering pump and drive pulley as an assembly out the bottom of the engine compartment.
Remove the power steering pump pulley as follows:
- Mount the pump in a vise using the mounting bosses.
- Remove the power steering pump pulley from the shaft using special puller tool C-4333, or equivalent.Do not press or hammer on the shaft of the pump. This will cause internal pump damage.
- Transfer parts to replacement pump, as required.
Install the power steering pump pulley as follows:
- Place the pulley onto the shaft and make sure it is installed squarely.
- Install the spacer provided with the replacement pump into the hub of the pulley.
- Insert the pulley installer tool C-4063 (without adapters) through the hole in the spacer. Thread the tool into the pump shaft and tighten the tool into the shaft.
- Hold the installer with one wrench so it does not rotate. Turn the hex down threaded rod of installer to push the pulley onto the shaft. Make sure the pulley does not become cocked during installation.
- Continue to push the pulley onto the shaft until the tool will not turn.
- Remove the installer tool and spacer. Turn the pulley and make sure it does not wobble. If it does, remove the pulley and check for a bent pump shaft, bent pulley or other malfunction.
- Install the power steering pump back into the vehicle from below the engine compartment. Install mounting bolts and tighten to 40 ft. lbs. (54 Nm).
- Correct orientation of the power steering pressure hose at the power steering pump must be maintained. Be sure the power steering hose is installed in the routing clip at the alternator (if equipped) prior to tightening tube fitting.
- Attach the power steering pressure hose on the outlet port of the pump and tighten fitting to 25 ft. lbs. (34 Nm).
- Install the hose from the remote fluid reservoir to the low pressure port on the power steering pump.
- Install the accessory drive belt over the power steering pulley. Lower the vehicle.
- Adjust the belt tension and connect the negative battery cable.
- Refill the pump reservoir to the correct level with Mopar Power Steering Fluid, or equivalent. Do not use any type of automatic transmission fluid. Start the engine and turn the steering wheel several times from stop to stop to bleed the air from the fluid in the system. Check and adjust fluid level as required.
- Test drive vehicle to verify repair.
BLEEDING THE SYSTEM
- Check the fluid level in the reservoir and fill to the correct level with the approved power steering fluid.
- Start the engine and allow it to idle with the transaxle in Park .
- Slowly turn the steering wheel all the way to the left and then all the way to the right. Turn it from lock to lock several times. Then, refill the fluid reservoir.
