REMOVAL
WARNING:
Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to
release built-up pressure. Carefully remove radiator cap by turning it all the way.
1. Remove front engine undercover with power tool.
2. 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.
3. Remove air duct (inlet) and air cleaner case assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT"
.
4. Remove reservoir tank and reservoir tank bracket.
5. Disconnect A/T fluid cooler hoses from radiator.

Install blind plug to avoid leakage of A/T fluid.
6. Removal radiator hoses (upper and lower) and reservoir tank hose. CAUTION:
Be careful not to allow engine coolant to contact drive belts.
7. Remove radiator cooling fan assembly. Refer to CO-21, "
COOLING FAN" .
8. Rotate two radiator upper mount brackets 90 degrees in the direction shown in the figure, and remove them.
9. Lift up and remove radiator. CAUTION:
Do not damage or scratch A/C condenser and radiator core
when removing.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter [SST: EG17650301 (J33984-A)]
and the radiator cap tester (commercial service tool). Refer to CO-11, "
LEAK CHECK" .

Start and warm up the engine. Visually make sure that there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapABS008FW

Check valve seat of radiator cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.

ComponentsABS00E80
Removal and InstallationABS009RE
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, "
