REMOVAL

WARNING:
Never 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.
1.Drain engine coolant from radiator. Changing Engine Coolant.

CAUTION:

- Replace the gasket with a new one.

INSPECTION AFTER REMOVAL

- Place a thread (A) so that it is caught in the valves of water control valve (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 full-open valve lift amount, lower the water temperature and check the valve closing temperature.
Standard: [1][2]Cooling System
