CAUTION
Do not stop the engine immediately when the engine coolant temperature
is above the maximum limit. If you stop the engine, the coolant
temperature increases suddenly and damage to the engine occurs.
Operate the engine at a RPM immediately above idle to help decrease the
coolant temperature.
(d) When the coolant temperature gauge points to the red area, between 212
°
F and
248
°
F (100
°
C - 120
°
C) continuously, it shows that the engine is above limits. If
you stop the engine, the coolant temperature increases suddenly and damage to
the engine occurs. Operate the engine at a RPM immediately above idle to help
decrease the coolant temperature.
(e) When the coolant temperature goes back to the green or yellow area, do the
items that follow:

Examine the engine area for leaks.

Examine the function of the thermostat.

Examine the coolant level.

Examine the fan belt for damage.

Make sure that the fan belt is not too loose.
CAUTION
Do not add a large quantity of cold water to the engine if the engine coolant
temperature is above the maximum limit. This can kill or blind you and cause
damage to the engine.
(3) Low engine coolant:
CAUTION
Use soft water, e. g. tap water, for coolant. Do not use hard water (river water).
Do not add a large quantity of cold water too quickly. When it is necessary to add cold
water, put the water in slowly. Follow the below instructions to add coolant:

Put together water, antifreeze and/or anti-rust fluid in the correct ratio.

Loosen the cap to the coolant tank with a wet rag to release the pressure in the
tank. After you release the pressure, continue to remove the cap. The fluid
released is hot and pressurized and can cause burns or blindness. Always keep
your face away from the cap on the coolant tank.

Add the water mix to the applicable coolant tank fill-line and then install the cap.
