HANDLING NOTE
w
Do not remove the radiator cap when the
engine and radiator are hot. Scalding hot
fluid and steam may be blown out under
pressure, which could cause serious in-
jury.
When the engine has cooled, open the ra-
diator cap by the following procedure:
Place a thick rag, like a towel, over the
radiator cap, slowly rotate the cap counter-
clockwise to the detent. This procedure al-
lows any residual pressure to escape.
When the hissing sound has stopped,
press down on the cap while turning coun-
terclockwise and remove it.
