Never open, service, or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
- Before servicing the vehicle, refer to the Precautions Section.
- Remove the drive belt.
- Drain the engine coolant.
- Remove the drive belt auto-tensioner pulley.
- Remove the 6 bolts securing the water pump, then remove the water pump (A).
- Inspect and clean the O-ring groove and mating surface of the water passage.
- Install the water pump with new O-ring (B) and tighten the 6 bolts to 106 inch lbs. (12 Nm).
- Clean up any spilled engine coolant.
- Install the drive belt auto-tensioner pulley.
Refill the radiator with engine coolant and bleed the air from the cooling system while running the engine with the heater valve open.
