Vehicle Care
10-19
1. 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
two or two and one-half turns.
If a hiss is heard, wait for that to
stop. This will allow any
pressure still left to be vented
out the discharge hose.
2. Keep turning the pressure cap
slowly, and remove it.
3. Fill the coolant surge tank with
the proper mixture, to the FULL
COLD mark. Wait about
five minutes, then check to see if
the level is below the mark. If the
level is below the FULL COLD
mark, add additional coolant to
bring the level up to the mark.
Repeat this procedure until the
level remains constant at the
FULL COLD mark for at least
five minutes.
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. Watch out for the
engine cooling fans.
By this time, the coolant level
inside the coolant surge tank
might be lower. If the level is
lower than the FULL COLD
mark, add more of the proper
mixture to the coolant surge tank
until the level reaches the FULL
COLD mark.
5. Replace the pressure cap. Be
sure the pressure cap is
hand-tight and fully seated.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
