50/50 mixture of clean, drinkable water and
DEX-COOL coolant at the coolant surge tank,
but be sure the cooling system, including
the coolant surge tank pressure cap, is cool
before you do it.
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 one-quarter of a
turn. If you hear a hiss, 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 indicated
level mark.
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
mixture to the coolant surge tank until
the level reaches the indicated
level mark.
5. Replace the pressure cap tightly.
6. Verify coolant level after the engine is
shut off and the coolant is cold.
If necessary, repeat coolant fill procedure

If the coolant still is not at the proper
level when the system cools down again,
see your dealer.
Caution

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

temperature gauge to warn of the engine
