RADIATOR
HANDLING NOTE
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 injury. 
When the engine has cooled, open 
the radiator cap by the following 
procedure:
Place a thick rag, like a towel, over 
the radiator cap, slowly rotate the 
cap counterclockwise to the de-
tent. This procedure allows any re-
sidual pressure to escape. When 
the hissing sound has stopped, 
press down on the cap while turn-
ing counterclockwise and remove 
it.
