Removing
Fastening the heater return pipe to the water pump
Removing the O-ring from the heater return pipe
Removal from the water pump of the top hose of a radiator
Fastening of a hose of a cooling liquid of a head of the block of cylinders to the water pump
Removing the water pump from a 6-cylinder gasoline engine
1. Remove the ground wire from the battery and drain the coolant from the cooling system.
2. Remove the auxiliary drive belt and belt tensioner.
3. Unscrew the power steering pump mounting bolts and move the pump to the side without disconnecting the hoses from it.
4. Remove the air filter and air intake.
5. Remove the distributor and auxiliary drive belt cover.
6. On early models, unscrew the six bolts securing the air conditioning compressor and move the compressor to the side without disconnecting the hoses from it.
7. Unscrew the bolt and remove the heater return pipe from the water pump. Remove the O-ring from the pipe (see fig. Fastening the heater return pipe to the water pump, Removing the O-ring from the heater return pipe). Remove the pipe from the mounting bracket on the radiator fan bracket.
8. On models with an oil cooler, unscrew the coolant supply line from the water pump and remove the O-ring. Remove the screw and remove the coolant pipe bracket from the intake manifold hanger.
9. Remove the thermostat.
10. Loosen clamps and disconnect cylinder head coolant hoses and upper radiator hose from water pump (see fig. Removing the upper radiator hose from the water pump, Attaching the cylinder head coolant hose to the water pump).
11. Unscrew 4 bolts and remove the water pump from the engine (see fig. Removing the water pump from a 6-cylinder gasoline engine). Remove the two bushings and remove the o-ring.
Installation
1. Using care, clean the mating surfaces of the water pump and cylinder block from the remnants of the old gasket.
2. Installation is carried out in the reverse order of removal, taking into account the following points.
3. Some of the water pump mounting bolts require the use of a rod and a magnet.
4. Tighten all bolts to the required torque.
5. New gaskets must be used when installing the water pump and thermostat housing. When installing the heater return hose, a new O-ring must be fitted to the hose.
6. Install and adjust the tension of the auxiliary drive belt.
7. Pour coolant into the cooling system.
