Removal and Installation
REMOVAL
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.
CAUTION:
Perform these steps after the coolant temperature has cooled sufficiently.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
- Remove the engine under cover. Refer to EXT-31, "ENGINE UNDER COVER : Removal and Installation".
- Drain engine coolant from radiator. Refer to CO-12, "Changing Engine Coolant".
- Remove water hose and heater thermostat assembly.
INSTALLATION
Installation is in the reverse order of removal.
- Refer to the following when installing water hoses.
| Water hose (1) | Installation side tube (2) | Direction of paint mark | Hose insertion depth (L) |
| Heater thermostat assembly | CVT oil warmer | Frontward | (A): 27 mm (1.06 in) (Hose end reaches the 2-stage bulge.) |
| Water hose | CVT oil warmer | Frontward | |
| Water outlet | Frontward | B): 27 mm (1.06 in) (Hose end reaches the end of water outlet tube.) |
- Refer to the followings when installing hose clamp.
CAUTION:
- Do not reuse hose clamp.
- Hose clamp should not interfere with the bulge of fluid cooler tube.

Inspection
INSPECTION AFTER REMOVAL
Heater Thermostat
- Fully immerse the heater thermostat 1 in a container (A) filled with water. Continue heating the water while stirring.
- Continue heating the heater thermostat for 5 minutes or more after bringing the water to a boil.
- Quickly take the heater thermostat out of the hot water, measure the heater thermostat within 10 seconds.
- Place dial indicator (A) on the pellet (B) and measure the elongation from the initial state.
Standard : Refer to TM-289, "Heater Thermostat".
- If out of standard, replace heater thermostat.
INSPECTION AFTER INSTALLATION
Start the engine, and check the joints for coolant leakage.
