The power steering pump is encased within the power steering pump housing (3A643) and power steering fluid reservoir. The power steering pressure hose (3A719) is attached with a quick-connect fitting, located below the power steering fluid reservoir. The fitting allows the line to swivel. This is normal and does not indicate an untorqued fitting. An identification tag is attached to the power steering fluid reservoir. The top line of this tag indicates the basic model number (HBC) and the suffix. NOTE: Always use these tags when requesting service assemblies as there may be slight differences in internal components. C-II Power Steering Pump, Exploded View

Disconnect the power steering return hose (3A713) at the pump and drain fluid. 2. Remove the power steering pressure hose (3A719) by unscrewing connector from the pump. 3. On the Aerostar 3.0L V-6 engine (6007), loosen the drive belt tensioner (6B209) and adjustment bolts.

On Ranger 3.0L V-6 engines, slacken belt tension by lifting drive belt tensioner in a clockwise direction. Remove drive belt (8620) from under drive belt tensioner and slowly lower pulley to stop. Remove the drive belt from the power steering pump pulley (3A733).

NOTE: If the drive belt requires servicing, refer to Section 03-05. Remove the drive belt from the power steering pump pulley. 5. Remove the oil dipstick tube. 6. Remove the power steering pump support (3C511). 7. Install Steering Pump Pulley Remover T69L-10300-B on the pulley.
Page 3 of 8 8. NOTE: Do not apply pressure on the power steering pump rotor shaft (3B559). Pressure will damage internal thrust areas of the power steering pump (3A674). While holding the remover tool nut stationary with a wrench, rotate the inner spindle of the remover tool clockwise until the pulley is pulled off the power steering pump rotor shaft. 9. Remove the bolts attaching the power steering pump to the A/C compressor mounting bracket (2882). Installation 1. Install the power steering pump on the A/C compressor mounting bracket. Install and tighten attaching bolts to 41-61 Nm (30-44 lb-ft). On 4.0L engine, tighten to 47-64 Nm (35-47 lb-ft). 2. Position the support on the A/C compressor mounting bracket. Install mounting bolts and tighten to 47-64 Nm (35-47 lb-ft). 3. NOTE: Fore/aft location of power steering pump pulley on power steering pump rotor shaft is critical. Incorrect belt alignment may cause drive belt squeal or chirp. Make sure pull-off groove on power steering pump pulley is facing front and flush with end of shaft ± 0.254mm (± 0.010 inch). Install the Steering Pump Pulley Replacer T65P-3A733-C and install the power steering pump pulley. 4. Install the drive belt on the power steering pump pulley. 5. On the 2.3L I-4, Ranger 3.0L V-6, and 4.0L V-6 engines, position and rotate drive belt on engine. While lifting drive belt tensioner in a counterclockwise direction (clockwise on Ranger 3.0L V-6), slide drive belt under drive belt tensioner and lower drive belt tensioner to drive belt. On Aerostar 3.0L V-6 engine, position the belt idler pulley (8678) assembly to give the drive belt the tension specified. Refer to belt tension check in Section 03-05. Tighten the drive belt tensioner and adjustment bolts to 47-64 Nm (35-47 lb-ft). 6. Install the power steering pump support, if removed. 7. Install the oil dipstick tube. 8. Install the pressure hose tube nut and new Teflon wagner into power steering pump valve outlet fitting (3D654) and tighten to 30-40 Nm (22-30 lb-ft). 9. Connect the power steering return hose to the power steering pump, and reposition the clamp. 10. Fill the power steering fluid reservoir with Motorcraft MERCON ATF Power Steering fluid meeting Ford specifications MERCON. Start the engine and turn the steering wheel (3600) from left to right without hitting stops to remove air from the system. 11. Check for leaks and recheck the fluid level. Add fluid if necessary to proper level as specified in Section 11-00. Power Steering Pump and Power Steering Pulley, 2.3L TPH Engine, Ranger Only
