Here is the procedure, according to the service manual. Sorry, I could not import the figures to reference.

For the 1.6L SOHC:

DESCRIPTION

The water pump on this vehicle is attached to the rear of the Power Steering pump to form an assembly

(Fig. 27). The water pump/power steering pump assembly is located on the front corner of the engine

(Fig. 29).

The water pump is bolted to the rear of the power steering pump. Driven by the power steering pump

shaft, the water pump's impeller is located inside a die-cast aluminum housing. The water pump housing has a built in outlet. The water pump also has a bolt-on inlet cover with two ports, one for incoming coolant from the radiator and the other for incoming coolant from the heater.

Both pumps (water and power steering) can be serviced separately. Remove the entire water pump/

power steering pump assembly, then disassemble it to service either pump.

For information on the power steering pump, (Refer to 19 - STEERING/PUMP - DESCRIPTION).

REMOVAL

NOTE: Before proceeding, review all Warnings and Cautions (Refer to 7 - COOLING - WARNING) and (Refer to 19 - STEERING - WARNING).

(1) Disconnect battery negative (-) terminal.

(2) Remove the accessory drive belt (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELT -

REMOVAL).

(3) Remove power steering fluid reservoir. (Refer to 19 - STEERING/PUMP/RESERVOIR - REMOVAL)

(4) Remove generator. (Refer to 8 - ELECTRICAL/CHARGING/GENERATOR - REMOVAL)

(5) Drain engine coolant (Refer to 7 - COOLING/ENGINE - STANDARD PROCEDURE - DRAIN

COOLING SYSTEM).

(6) If equipped with air conditioning, remove A/C compressor upper mounting bolts.

(7) Raise vehicle (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE).

(8) Remove accessory drive belt splash shield.

(9) If equipped with air conditioning, remove A/C compressor lower mounting bolts. Reposition A/C

compressor to allow access to power steering pump/water pump lower mounting bolts. Do not overextend A/C hoses while performing this.

(10) Remove radiator hose at inlet to water pump.

(11) Remove heater tube hose at water pump.

(12) Lower vehicle.

(13) Remove the bolt fastening the power steering pressure hose to the reservoir bracket (Fig. 28).

(14) Back out the tube nut securing the power steering fluid pressure hose to the power steering pump and remove the hose from the pump (Fig. 28). Cap off hose end and pump pressure port.

(15) Remove coolant outlet connector hose at water pump outlet.

(16) Remove all four power steering pump mounting bolts. (Fig. 29)

(17) Remove power steering pump and water pump as an assembly.

(18) To separate the power steering pump from the water pump, (Refer to 7 - COOLING/ENGINE/WATER PUMP - DISASSEMBLY).

(19) If the power steering pump pulley needs to be removed, (Refer to 19 - STEERING/PUMP - DISASSEMBLY).

DISASSEMBLY

(1) Remove the three hex drive bolts and washers that attach the power steering pump to the water

pump (Fig. 27).

(2) Use the following steps to access the water pump impeller hex.

(a) Place a 1⁄4 inch drive 10 mm socket in through the coolant inlet tube, then back it into the heater hose fitting area as shown (Fig. 30). Backing the socket into the heater hose fitting makes it easier to perform the following step.

(b) Holding the socket in this position, insert a 1⁄4 inch drive extension (6 inches in length or longer) in through the heater hose fitting into the rear of the 10 mm socket.

(c) Push the socket with the extension into the pump placing the socket on the hex built into the

center of the water pump impeller.

(3) While holding the power steering pump shaft from turning using a hex wrench in the pulley end of

the shaft, loosen the impeller by rotating the 1⁄4 inch drive extension counterclockwise using a ratchet. The water pump will rise off of the power steering pump as the impeller is rotated.

(4) Once the threads have been disengaged, remove the entire water pump assembly from the power steering pump. If the water pump will be used again, the 10 mm socket and extension can be left inside the water pump until reassembly is completed.

(5) If the water pump inlet cover needs to be removed, remove the seven fasteners around the perimeter of the pump and remove the cover. Discard the housing O-ring type seal.

(6) If the power steering pump pulley needs to be removed, (Refer to 19 - STEERING/PUMP - DISASSEMBLY).

NOTE: For reassembly, (Refer to 7 - COOLING/ENGINE/WATER PUMP - ASSEMBLY).

ASSEMBLY

(1) If the water pump inlet cover needs to be installed on the water pump:

(a) First apply Mopart Dielectric Grease or equivalent to a NEW water pump O-ring seal.

(b) Place the O-ring seal in the housing groove where the cover contacts the housing.

(c) Install the seven fasteners around the perimeter of the pump. Tighten them to 12 N·m (105 in.lbs.) torque.

(2) If a pulley needs to be installed on the power steering pump, (Refer to 19 - STEERING/PUMP -

ASSEMBLY).

(3) Place the water pump assembly onto the power steering pump shaft.

(4) Rotate the water pump so the water pump outlet is near the water pump upper mounting holes

(hole with dowel guide). Arrange the three pump fastener holes so they line up.

(5) If the water pump impeller hex has not been accessed with a socket, use the following steps to

access the water pump impeller hex.

(a) Place a 1⁄4 inch drive 10 mm socket in through the coolant inlet tube, then back it into the heater hose fitting area as shown (Fig. 30).

(b) Holding the socket in this position, insert a 1⁄4 inch drive extension (6 inches in length or longer) in through the heater hose fitting into the rear of the 10 mm socket.

(c) Push the socket with the extension into the pump placing the socket on the hex built into the center of the water pump impeller.

(6) While holding the power steering pump shaft from turning using a hex wrench in the pulley end of

the shaft, tighten the water pump impeller rotating the 1⁄4 inch drive extension clockwise using a ratchet. This will draw the water pump in toward the power steering pump. Tighten the impeller to 26 N·m (19 ft. lbs.) torque.

(7) Remove the 10 mm socket, 1⁄4 inch extension and ratchet from the water pump. Remove the hex

wrench.

(8) Align the three pump fastener holes and install the three hex drive bolts with washers (Fig. 27).

Tighten the bolts to 26 N·m (19 ft. lbs.) torque.

(9) Install assembly on the vehicle. (Refer to 7 - COOLING/ENGINE/WATER PUMP - INSTALLATION)

INSTALLATION

NOTE: Water pump and power steering pump must be attached to one another before installation in vehicle. For proper procedure, (Refer to 7 - COOLING/ ENGINE/WATER PUMP - ASSEMBLY).

(1) Install water pump/power steering pump assembly into engine compartment in reverse of how

it was removed.

(2) Install all four power steering pump mounting bolts (Fig. 29). Tighten bolts to 28 N·m (21 ft. lbs.)

torque.

(3) Install coolant outlet connector hose at water pump outlet. Install clamp.

(4) Using a lint free towel, wipe clean the open power steering hose end and the power steering

pump port. Replace the used O-ring with new. Lubricate the O-ring with power steering fluid.

(5) Attach the power steering fluid pressure hose to the pump outlet port (Fig. 28). Do not tighten the

tube nut at this time.

(6) Install the bolt fastening the power steering pressure hose to the reservoir bracket (Fig. 28).

(7) Tighten power steering pressure hose tube nut at power steering pump to 28 N·m (21 ft. lbs.) torque.

(8) Raise vehicle.

(9) Install heater tube hose at water pump fitting. Install clamp.

(10) Install radiator hose at inlet to water pump. Install clamp.

(11) If equipped with air conditioning:

(a) Position A/C compressor, align mounting holes and install, but do not fully tighten, A/C compressor lower and upper mounting bolts.

(b) Lower vehicle.

(c) Tighten A/C compressor upper mounting bolts to 28 N·m (21 ft. lbs.) torque.

(d) Raise vehicle.

(e) Tighten A/C compressor lower mounting bolts to 28 N·m (21 ft. lbs.) torque.

(12) Install drive belt splash shield.

(13) Lower vehicle.

(14) Install generator (Refer to 8 - ELECTRICAL/CHARGING/GENERATOR - INSTALLATION).

(15) Install power steering fluid reservoir. (Refer to 19 - STEERING/PUMP/RESERVOIR - INSTALLATION)

(16) Install accessory drive belt (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELT -

INSTALLATION).

(17) Connect battery negative (-) terminal.

(18) Fill cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE - FILLING COOLING

SYSTEM).

(19) Perform POWER STEERING PUMP INITIAL OPERATION procedure. (Refer to 19 - STEERING/

PUMP - STANDARD PROCEDURE)

(20) Check for leaks at all hose connections.
