Vehicle Care
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
slowly, and remove it.
3. Fill the coolant surge tank with
the proper DEX-COOL coolant
mixture until the level inside
stabilizes at the FULL COLD
mark on the front of the
surge tank.
4. With the coolant surge tank
pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during this
procedure, watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge tank
until the level stabilizes at the
FULL COLD mark on the coolant
surge tank.
5. Replace the pressure cap tightly.
Check the level in the surge tank
when the system has cooled
down. If the coolant is not at the
proper level, repeat Steps 1

then reinstall the pressure cap.
If the coolant is not at the proper
level when the system cools

tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
