How to Add Coolant to the 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.

Caution

Failure to follow the specific coolant fill
procedure could cause the engine to
overheat and could cause system
damage. If coolant is not visible in the
surge tank, contact your dealer.

The coolant surge tank pressure cap can be
removed when the cooling system, including
the surge tank pressure cap and upper
radiator hose, is no longer hot.

1. Turn the pressure cap slowly

counterclockwise. If a hiss is heard, wait
for that to stop. A hiss means there is
still some pressure left.

2. Keep turning the pressure cap slowly and

remove it.

3. If topping off the level in the coolant

surge tank, add the proper mixture until
the level reaches the mark on the front
of the tank and replace the cap. Operate
the vehicle. Repeat steps 1

3, as

necessary.
If filling the system (such as after
servicing), follow the Automatic Coolant
Service Fill Instructions.

Caution

If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.

Automatic Coolant Service Fill
Instructions

This feature assists in filling and removing
air from the cooling system after service of
components or when coolant is added after
being too low.

To activate the fill and air removal process:

1. With a cold system, add coolant to the

indicated mark on the surge tank.

2. Replace the cap on the surge tank.
3. Connect the vehicle to a battery charger.
