Water Pump

REMOVAL & INSTALLATION

CAUTION
When draining the 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 quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

9. Raise and safely support the vehicle on jackstands.
10. Remove the flywheel housing cover.
11. Remove the oil pan, oil pan plate and oil strainer.
12. Remove the air suction manifold bracket from the air manifold and crankcase cover.
13. Remove the water pump cover retainer bolts from the crankcase cover. Lift the water pump cover off and clean all gasket material from both mating surfaces.
14. Remove the water pump impeller bolt and impeller, as well as the seal.
15. Install a new water pump seal using seal installer 499795400 or equivalent. Install the water pump impeller and bolt. Tighten the bolt to 7–9 ft. lbs. (9–12 Nm).
16. Install the water pump cover to the crankcase cover. Tighten the retainer bolts to 8–12 ft. lbs. (10–16 Nm).
17. Lower the vehicle and install all remaining components. Tighten to specifications.
18. Refill the crankcase with clean oil. Refill the cooling system.
19. Start the vehicle and check for leaks.

1.6L, 1.8L and 2.7L Engines

1. Drain the coolant into a suitable container.
2. Disconnect the radiator outlet hose and water bypass hose from the water pump.
3. Loosen the pulley nuts. Loosen the alternator assembly and remove the drive belt.
4. Remove the front belt cover.
5. Unfasten the water pump mounting bolts and remove the water pump.
6. Installation is the reverse of removal.
7. Clean the gasket material from both mating surfaces. Always use new gaskets during installation.
8. Install the water pump and pump mounting bolts. Tighten the mounting bolts to 7–8 ft. lbs. (9–10 Nm).
9. Install the alternator drive belt and drive belt cover. Adjust the drive belt to the proper tension. Tighten the water pump pulley bolts to 7–8 ft. lbs. (9–10 Nm).
10. Fill the radiator with coolant. Start the engine and allow it to reach operating temperature. Check for leaks.

9. Remove the water pump retainer bolts.
10. Remove the water pump.
11. Installation is the reverse of removal. Pay particular attenstion to the following information.
12. Clean the gasket mating surfaces thoroughly. Always use new gaskets during installation.
13. Install the water pump and tighten the bolts, in sequence, to 7–10 ft. lbs. (10–14 Nm). After tightening the bolts once, retighten to the same specification again.
14. Fill the system with coolant and connect the negative battery cable.
15. Start the engine and allow it to reach operating temperature and check for leaks.
