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 coolant.
NOTE
Do not overfill a cooling system. Ex-
cess
coolant may result in overflow,
loss of antifreeze, and reduced corro-
sion protection.
1. Fill cap
2. Sight glass
1. If your cooling system is built with
an air bleed valve in the upper
engine coolant pipe, open it before
filling the surge tank.
2. Close any open coolant drain
valves in the lower engine coolant
pipe.
3.
Remove the surge tank fill cap (1).
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 "MIN" line). It may be
necessary to pause for 1 minute
and then re-fill if the fluid level
dropped.
5. Close the air bleed valve that was
opened in Step 1.
6. Start the engine and idle at low
rpm.
7. During low rpm idle, air will purge
from the cooling system via the
surge tank's coolant fill cap. This
will lower the coolant level in the
surge tank. Continue to fill the
surge tank until the coolant level
remains approximately 1/2 in.
above the "MIN" line. This may
take up to 2 minutes, depending on
the outside temperature.
