3. Fill the coolant surge tank with the proper
DEX-COOL
®
coolant mixture, to the cold fill line.
4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can feel
the upper radiator hose getting hot. 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 DEX-COOL
®
coolant mixture
to the coolant surge tank until the level reaches the
cold fill line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight.
Check the level in the surge tank when the cooling
system has cooled down. If the coolant isn’t at
the proper level, repeat Steps 1 through 3 and reinstall
the pressure cap. If the coolant isn’t at the proper
level when the system cools down again, see your
retailer.
