(2) Coolant Temperature
The engine performance will be adversely affected if engine coolant
temperature is too hot or too cold.
The normal coolant temperature is 75 to 90°C (167 to 194°F).
Overheating
WARNING:
If the Engine Coolant Temperature Gage shows an overheat
condition or you have other reason to suspect the engine may
be overheating, continued operation of the engine (other than
as spelled out here) even for a short period of time may result
in a fire and the risk of personal injury and severe vehicle or
equipment damage. Take immediate action as outlined
following.
If you see or hear escaping steam or have other reason to suspect
there is a serious overheat condition, stop and park the machine or
equipment as soon as it is safe to do so and then turn off the engine
immediately and get out of the machine or equipment.
The engine cooling system may overheat if the engine coolant level is
too low, if there is a sudden loss of engine coolant (such as hose
splitting) or if other problems occur. It may also temporarily overheat
during severe operating condition such as:
• Climbing a long hill on a hot day.
• Stopping after high rpm.
