comes first). DO NOT drain the radiator fluid
when hot.

valve located on the bottom left side of the

cap.

when it feels cool to the touch, and always
open it slowly to relieve any built-up pressure.

the fluid completely. Dispose of the used
fluid according to city, state, and federal

the expansion tank. Fill only to the bottom
of the fill tube, approximately 50% of tank
capacity, to ensure enough air volume is
present for coolant expansion.
