Do not remove radiator cap when the 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.
REMOVAL
1. Drain engine coolant from radiator. Refer to CO-11, "Changing Engine Coolant".
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belt.
2. Remove air duct (inlet). Refer to EM-27, "
Exploded View".
3. Remove reservoir tank as follows:
a. Disconnect reservoir tank hose.
b. Release the tab (A) in the direction shown by the arrow ( ).
c. Lift up while removing the reservoir tank hose, and remove it.
4. Disconnect harness connector from fan motor, and move harness aside.
5. Disconnect A/T fluid cooler hoses if equipped.
Install plug to avoid leakage of A/T fluid if equipped.
6. Remove radiator hoses (upper and lower).
7. Remove radiator core support cover.
8. Remove radiator core support (upper) bolts, bolts of stationary
part on the radiator core support side and clip. Lift radiator
assembly (1) from radiator (upper) mount part of radiator core
support (upper) (2).

INSPECTION AFTER REMOVAL
WARNING:
Use a protector to prevent a burn during the work.
Thermostat
Place a thread (A) so that it is caught in the valves of thermostat
(1). Immerse fully in a container (B) filled with water. Heat while
stirring.
The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
Continue heating. Check the full open valve lift amount.
After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.
If out of the standard, replace thermostat.
INSPECTION AFTER INSTALLATION
Check that the reservoir tank cap is tightened.
Check for leaks of engine coolant using suitable tools. Refer to CO-11, "
Inspection".
Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.
