4. With the coolant surge tank cap
off, start the engine and let it
run until the upper radiator hose
starts getting hot. Watch out
for the engine cooling fan(s).
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 reaches the
mark pointed to on the front of
the coolant surge tank.
5. Replace the cap. Be sure the
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.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant surge tank.
