s WARNING

G 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. Be sure to wait until the engine has cooled.

slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the his-

sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
