{CAUTION:

You can be burned if you spill coolant on hot

engine parts. Coolant contains ethylene glycol

and it will burn if the engine parts are hot

enough. Do not spill coolant on a hot engine.

If no coolant is visible in the surge tank, add coolant

as follows:

1. You can remove the coolant surge tank pressure

cap when the cooling system, including the coolant

surge tank pressure cap and upper radiator hose,

is no longer hot. Turn the pressure cap slowly

counterclockwise about one-quarter turn and

then stop.

If you hear a hiss, wait for that to stop. A hiss

means there is still some pressure left.

2. Then keep turning the pressure cap slowly, and

remove it.
