Coolant pump
To remove
Note: A small amount of leakage of coolant across the surface of the face seal in the coolant pump is normal.
Its purpose is to provide lubrication for the seal. There is a hole in the water pump body to allow coolant to
drain. Small amounts of coolant might be seen to leak intermittently from the drain hole during the engine
operation cycle. Signs of a small leakage through the drain hole are not an indication that the pump is faulty.
Coolant stains or intermittent drops of coolant from the hole, indicate normal operation of the pump.
1 Remove the fan, see Operation 12-8.
2 Remove the fan belt, see Operation 14-3.
3 Disconnect the hose connections of the coolant pump.
4 Remove the four flange head setscrews from the pump pulley and remove the pulley from the hub.
5 Remove the five setscrews (A4) and (A2) that secure the pump to the timing case and remove the pump
from the engine.
6 If it is necessary to remove the adaptor plate (A5) from the pump body (A6) release the nut and bolt (A1)
and the Allen screw (A3).
Note: If the pump is to be dismantled, it will be necessary to use an extractor to remove the pulley hub from
the pump shaft.
