The engine should operate within the normal temperature range. The sensor for jacket water coolant temperature must be fully submerged to detect the temperature correctly. If the engine is operating above the normal temperature range, perform the following procedure:
Reduce the load and the engine rpm.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load and rpm.
High inlet manifold air temperature increases the risk of engine damage. Maximum inlet air temperature is 115 °C (235 °F).
