ComponentsNBS003K5
Removal and InstallationNBS003K6
CAUTION:

When removing water pump assembly, be careful not to get engine coolant on drive belts.

Water pump cannot be disassembled and should be replaced as a unit.

After installing water pump, connect hose and clamp securely, then check for leaks using the radi-
ator cap tester (commercial service tool) and the radiator cap tester adapter [SST: EG17650301
(J33984-A)].
REMOVAL
1. Remove front engine undercover with power tool.
2. Remove drive belts. Refer to EM-15, "
DRIVE BELTS" .
3. Drain engine coolant from radiator. Refer to CO-11, "
Changing Engine Coolant" .
CAUTION:

Perform this step when the engine is cold.

Do not spill engine coolant on drive belts.
4. Remove air duct (inlet), power duct and air cleaner case assembly. Refer to EM-17, "
AIR CLEANER AND
AIR DUCT" .
5. Remove water drain plug (front) on water pump side of cylinder block to drain engine coolant from engine inside.
6. Remove chain tensioner cover and water pump cover from front timing chain case.
