System Check: Notes

WARNING: Never remove the filler cap nor radiator cap when the engine is hot. Serious burns could be caused by hot high pressure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by first turning it a quarter turn to allow built-up pressure to escape. Then turn the cap all the way off.
