- Remove front brackets, adjusters, and pulleys necessary to access the accessory belt components. Remove the engines serpentine and or V style drive belts, and clean and lubricate any idlers, pivots, or tensioner assemblies for later reassembly. Clean the pulley grooves to remove built up rubber and debris that will cause premature wear / noise issues with the belt(s). Check all accessories, idlers, and tensioners for bearing deflection while apart for the replacement of the power steering pump. The primary tensioner was replaced due to improper tension. Clean the exterior of the power steering pump housing at the lines attachment points to prevent foreign material from entering the system. Disconnect the pressure and return lines at the pump. Clean the threads on the lines and flush the system to remove any contaminants that may have been dispersed through the system from the faulty pump, age, and or normal wear. Remove the pump and transfer the reservoir from the old pump to the new pump housing where applicable. Install the new pump onto its mount and torque to specification. Reattach the pressure and return lines to the new pump using new sealing washers or gaskets as required. Reinstall the accessory drive and or serpentine belt(s) and reassemble the removed components. Fill the power steering system with the specified amount and type of new steering fluid and purge the air from the system. Install new serpentine drive belts, and run the engine to check for proper operation of the idler and tensioner pulleys. Verify belt deflection and alignment of the engines accessories, and lock all manually adjusted tensioners as required. Road test the vehicle to verify correct operation of the power steering system and recheck the system for the correct fluid level as well as to ensure there are no leaks from the power steering pump.
- The vehicles Steering pump is wet at its front seal, and has a slight reservoir leak at the pump body. Due to age and deterioration, the most cost effective approach is to replace the pump with a new unit. Issues with the main tensioner and drive belts were uncovered during diagnostics. See below for replacement of the required components.
