BURN PREVENTION 2
q
To prevent burns from hot water or steam spurting out
when checking or draining the coolant, wait for the water to
cool to a temperature where it is possible to touch the
radiator cap by hand before starting the operation. Even
when the coolant has cooled down, loosen the cap slowly
to relieve the pressure inside the radiator before removing
the cap.
q
To prevent burns from hot oil spurting out when checking or
draining the oil, wait for the oil to cool to a temperature
where it is possible to touch the cap or plug by hand before
starting the operation. Even when the oil has cooled down,
loosen the cap or plug slowly to relieve the internal
pressure before removing the cap or plug.
