Coolant Pump Removal and Installation

The coolant pump is driven by the V-belt. The fan hub is attached to the front of the pump shaft.

REMOVAL
1. Drain the coolant.
2. Remove the V-belt. Refer to V-Belt Removal, Installation and Tensioning.
3. Remove the radiator.
4. Remove the pulley mounting bolts. Hold the belt from turning while pressing it. Remove the pulley from the hub.

2. Remove the four coolant pump mounting bolts. On the 6-cylinder engine, remove the nuts instead of the bolts shown in the illustration. Refer to the accompanying illustration.

3. Screw two M6 bolts into the holes (arrows in the accompanying illustration) and press the pump evenly away from the engine. Make sure the pump does not tilt. On the diesel engine, the threaded holes for pressing off the pump are located vertically one above the other (arrows in the previous illustration).

INSTALLATION
1. Remove the press-off bolts. Replace the pump O-ring with a new one and lubricate it with silicone oil or petroleum jelly.
2. Install the pump with a new gasket and tighten it evenly. Tighten the bolts to the torque specified in the Specifications, depending on the thread.
3. Tighten the four pulley mounting bolts to the torque specified in the Specifications.
4. Install the V-belt and tension it. Refer to V-Belt Removal, Installation and Tensioning.
5. Install the radiator. Refer to Radiator Removal and Installation.
6. Fill the system with coolant and bleed air. Refer to Coolant Replacement. Coolant Freeze Protection Check. Visual Inspection of the Cooling System.
7. Start and warm up the engine. Check the hose connections and the pump for leaks.
