level in the tank is below the line marked
MIN.
The minimum fluid level is determined by
the line on the surge tank indicated by the
letters "MIN". This indicator is located
below the fill cap. The cooling system will
need fluid if the surge tank level does not
rise to the "MIN" line regardless if the
system is hot or cold.

How to Add Coolant to the Cooling
System
Add coolant through the surge tank fill cap.
Do not remove the pressure cap to fill the
cooling system.
WARNING
Do not remove the radiator fill cap
while the engine is hot. Scalding
steam and fluid under pressure may
escape. You could be badly burned.
Failure to comply may result in death
or personal injury.
NOTE
If frequent topping off is necessary and
there are no visible signs of coolant
leaks when the engine is cold, check
for leaks with the engine operating at
normal temperature.
NOTE
Do not use the pressure cap to fill the
surge tank with fluid.
NOTE
Do not overfill a cooling system. Ex-
cess coolant may result in overflow,
loss of antifreeze, and reduced corro-
sion protection.
1. If your cooling system is built with
drain valves in the upper engine
coolant pipe, open them before
filling the surge tank.
2. Close any open coolant drains in
the system.
3. Remove the surge tank fill cap (do
not remove the surge tank
pressure cap).
4. Fill the system with premixed
coolant through the surge tank fill
cap. Pour coolant at a steady flow
rate until the surge tank is full (to
the base of the fill neck). It may be
necessary to pause for 1 minute
and then re-fill if the fluid level
dropped.
5. Close any drain valves that were
opened in Step 1.
6. Start the engine and idle at low
rpm.
