Coolant Pump, Removing and Installing

Coolant pump, removing and installing

Note: Coolant pump is bolted to bracket for generator, power steering pump and viscous fan.

- Lock carrier in service position

Removing

CAUTION: Before disconnecting the battery:
Stop the engine.
Determine the correct coding for the anti-theft radio.
Switch the ignition off (also applies when connecting the battery). Failure to do so may damage the Engine Control Module (ECM).






- Switch ignition off and disconnect battery Ground (GND) strap.
- Remove ribbed belt [1][2]Procedures
- Remove viscous fan (with belt pulley) Service and Repair
- Remove V-belt. [1][2]Procedures

Note: Ribbed belt for A/C compressor and torque support remains installed.

- Drain coolant. Service and Repair






- Loosen clamps for coolant hoses -1- and -2-
- Remove coolant hose to radiator at coolant line.
- Remove intake air duct between intake manifold and charge air cooler.
- Remove mounting bolts for generator.
- Remove generator toward front.
- Disconnect wiring from removed generator.

Unbolt following supports and braces from bracket for generator, power steering pump and viscous fan:
- Intake manifold support
- Support for torque support bracket
- Brace to cylinder block (remove completely)






- Remove bracket for generator, power steering pump and viscous fan bolts -1- through -6-.
- Secure bracket for generator, power steering pump and viscous fan to left side using wire.

Note: Power steering pump remains installed.

- Pull off coolant hoses from coolant pump and coolant thermostat housing.






- Unbolt coolant pump housing from toothed belt cover (arrow).
- Remove coolant pump.






- Unbolt impeller housing -1- from pump housing -4-.

Installing

Installation is the reverse of removal, noting the following:
- Clean sealing surfaces of both housings.
- Replace gasket and O-ring.
- Insert T-head bolt into coolant pump bore.






- Mount bracket for generator, power steering pump and viscous fan with coolant pump on cylinder block and tighten bolts to 30 Nm in numerical sequence.
1. Tighten bolt -A
2. Tighten bolt -B
3. Tighten bolt -C
4. Tighten bolt -D
5. Tighten bolt -E
6. Tighten bolt -F

- Install viscous fan Service and Repair
- Install ribbed belt [1][2]Procedures

Note: When installing ribbed belt, check for correct seating on belt pulley.

- Install V-belt [1][2]Procedures
- Fill up with coolant Service and Repair

WARNING! The cooling system is pressurized when the engine is warm. When opening the expansion tank, wear gloves and other appropriate protection, cover the cap using a cloth, and open carefully to relieve system pressure slowly.

- Switch ignition off and reconnect battery Ground (GND) strap.

Warning Be sure the ignition is switched OFF. Failure to do so may damage the Engine Control Module (ECM)

- After connecting battery, enter anti-theft code for radio.
Refer to Radio Operating Manual
- Fully close power windows to stop.
- Operate all power window switches again for at least one second in "close" direction to activate "one-touch" opening/closing function.
- Set clock to correct time.
