How to Add Coolant to the
Coolant Surge Tank
{
Warning
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
{
Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
If coolant is needed, be sure the
cooling system is cool, then add the
proper DEX-COOL coolant mixture
directly to the surge tank.
1. Open the Hatch/Trunk. See
Hatch (Trunk) 0 23.
2. When the cooling system,
including the coolant surge
tank pressure cap and engine,
is no longer hot, remove the
pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that
to stop. A hiss means there is
still some pressure left.
3. Keep turning the pressure cap
slowly, and remove it.
4. Fill the coolant surge tank with
the proper mixture until the
level inside stabilizes at the
COLD FILL indicator in the
surge tank.
5. With the coolant surge tank
pressure cap off, start the
engine and let it run until the
engine is hot.
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 COLD FILL indicator in the
coolant surge tank.
