WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur
from high pressure
engine coolant escaping from the radiator. Wrap a thick cloth around the
radiator cap. Slowly turn it a
quarter of a turn to release built-up pressure. Carefully remove radiator cap by
turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings
to prevent fluid from spilling.
REMOVAL
CAUTION:
Perform when the engine is cold.
- Partially drain coolant from radiator. Refer to CO-11, "Changing
Engine Coolant".
- Remove engine room cover. Refer to EM-23, "Removal and
Installation"
- Remove front air duct and air cleaner case assembly. Refer to
EM-24, "Removal and Installation".
- Disconnect electric throttle control actuator coolant hoses.
- Remove radiator hose (upper) and both heater hoses.
- Remove connector(s) from heater pipe.
- Remove engine coolant temperature sensor on water outlet.
- Remove water outlet, heater pipe, water connector, and water
bypass pipe nuts and bolts
INSTALLATION
- Installation is in the reverse order of removal.
- Securely insert each hose, and install a clamp at a position where
it does not interfere with the pipe
bulge.
CAUTION:
Do not reuse gasket.
- When inserting heater pipe and water bypass pipe into water
connector, apply neutral detergent to new
O-rings.
CAUTION:
Do not reuse O-rings.
- After installation refill engine coolant and check for leaks. Refer to
