WARNING:
Never remove the radiator cap when the engine is hot;
serious burns could be caused by high pressure fluid escap-
ing from the radiator.
Wrap a thick cloth around the cap and carefully remove by
turning it a quarter turn to allow built-up pressure to escape.
Then continue to turn the cap until it can be removed safely.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
