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 to be filled if the level is not above the
"MIN" line, regardless of engine
temperature.

How to Add Coolant to the Cooling
System
WARNING
DO NOT remove the coolant fill cap
while
the engine is hot. Scalding
steam and fluid under pressure may
escape and cause serious burns. Fail-
ure to comply may result in personal
injury or death.
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.
