Engine Coolant System: Inspection [QR25DE]: Notes
WARNING:
- Never remove the radiator cap or reservoir tank cap when the engine is hot. Serious burns could occur from high pressure fluid escaping from the radiator or reservoir.
- 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 down and turning it all the way.
