WARNING:
Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator.
REMOVAL
1. Drain engine coolant from radiator. Refer to CO-32, "DRAINING ENGINE COOLANT" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Disconnect radiator hose (upper and lower).
3. Remove reservoir tank hose and radiator mounting bracket.
4. Remove radiator and cooling fan assembly.
CAUTION:
Do not damage or scratch 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 (special service tool:
EG17650301) and the radiator cap tester (commercial service tool). Refer to CO-32, "
CHECKING RADIA-
TOR SYSTEM FOR LEAKS" .
