3.0L Engines

The 3.0L engines in all vehicles (with the exception of Premier and Monaco) use a water pump which bolts directly to the engine block, and uses a gasket for pump-to-block sealing. The pump is serviced as a unit.

The water pump is driven by the timing belt. Refer to the timing belt procedures in this section to provide access to the water pump.

1. Disconnect the negative battery cable.
2. Drain the cooling system. Refer to for this procedure.
3. Remove the timing belt and related components.
4. Remove the water pump mounting bolts, then separate the pump from the water inlet pipe and remove the pump from the engine.

To install:

5. Replace the water pump with a new one if it exhibits any of the following defects.
A. Damage or cracks on the pump body.
B. Coolant leaks, if the shaft seal is leaking, evident by traces of coolant leaks from the vent hole.
C. The impeller rubs on the inside of the pump.
D. Excessively lose or rough turning bearing.

6. Clean all gasket and O-ring surfaces on the pump and water pipe inlet tube.
7. Install a new O-ring onto the water inlet pipe. Wet the O-ring with water to facilitate easier installation.

Keep the O-ring free of oil or grease.

8. Install a new gasket onto the water pump and install the pump inlet opening over the water pipe. Press the assembly to sit the water pipe into the pump housing.
9. Install the water pump mounting bolts and tighten them to 20 ft. Lbs. (27 Nm).
10. Refer to the timing belt procedures once again, then install the timing belts and the other components removed in order to gain access to the water pump.
11. Refill the cooling system. This system uses a self-bleeding thermostat, so there is no need to bleed the system.
12. Connect the negative battery cable and road test the vehicle. Check for any coolant or oil leaks after the engine has warmed up to the normal operating temperature.
