Precautions When Handling Fluids at High
Temperature
Immediately after operations are stopped, the coolant, engine
oil, and hydraulic oil are at highest temperatures and the radiator
and hydraulic tank are still under pressure. Attempting to
remove cap, drain the oil or coolant, or replacing the filters may
lead to serious burns. Always wait for the temperature to go
down, and follow the specified procedures when carrying out
these operations.
To prevent hot coolant from spurting out, stop engine, wait for
the coolant to cool, then loosen the cap slowly to relieve the
pressure.
To prevent hot oil from spurting out, stop engine, wait for the oil
to
cool, then loosen the cap slowly to relieve the pressure.
