WARNING
A hot radiator is under pressure. Therefore,
do not remove the radiator cap when the
engine is hot. Scalding hot fluid and steam
may be blown out, which could cause seri-
ous injury. When the engine has cooled,
open the radiator cap as follows:
Place a thick rag or a towel over the radia-
tor cap and slowly turn the radiator cap
counterclockwise toward the detent to
allow any residual pressure to escape.
When the hissing sound has stopped, turn
the radiator cap counterclockwise while
pressing down on it and then remove it.
