WATER PUMP
Check for rough operation due to excessive end play.
If anything is found, replace water pump.
INSPECTION AFTER INSTALLATION
Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-8, "
Inspection".
Start and warm up the engine. Visually check that there is no leakage of engine coolant.

Removal and InstallationINFOID:0000000003793183
REMOVAL
1. Drain engine coolant from radiator drain plug at the bottom of radiator, and from water drain plug at the
front of cylinder block. Refer to CO-8, "
Draining" and EM-107, "Exploded View".
CAUTION:
Perform this step when the engine is cold.
Never spill engine coolant on drive belt.
2. Remove reservoir tank of radiator, and move it aside. Refer to CO-13, "
Exploded View".
3. Remove intake valve timing control solenoid valve (bank 2). Refer toEM-52, "
Exploded View".
4. Disconnect radiator hose (lower) from water inlet and thermostat assembly.
5. Remove water inlet and thermostat assembly (1).
CAUTION:
Never disassemble water inlet and thermostat assembly.
Replace them as a unit, if necessary.
INSTALLATION
Note the following, and install in the reverse order of removal.
Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.
1. Gasket 2. Water inlet and thermostat assembly 3. Clamp
4. Radiator hose (lower)
A. To radiator

INSPECTION AFTER REMOVAL
1. Check valve seating condition at ordinary room temperatures. It should seat tightly.
2. Check valve operation.
If the malfunctioning condition, when valve seating at ordinary
room temperature, or measured values are out of the standard,
replace water inlet and thermostat assembly.
INSPECTION AFTER INSTALLATION
Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-8, "
Inspection".
Start and warm up the engine. Visually check that there is no leakage of engine coolant. Thermostat (Standard) : Refer to CO-27, "
Thermostat".
