the surge tank pressure
cap—even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap.
If coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done.

including the radiator pressure
cap and upper radiator hose, is no longer hot. Turn the pressure
cap slowly counterclockwise
until it first stops. Do not press
down while turning the
pressure cap.
If a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap, but now push down as you turn
it. Remove the pressure cap.3. Fill the radiator with the properDEX-COOL coolant mixture, up
to the base of the filler neck. See
Recommended Fluids and
Lubricants on page 11‑12 for
more information about the
proper coolant mixture.
4. Fill the coolant recovery tank to the COLD FILL mark.
5. Reinstall the cap back on the coolant recovery tank, but leave
the radiator pressure cap off.
