BURN PREVENTION
Hot coolant
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 cool-
ant has cooled down, loosen the cap slowly to relieve the
pressure inside the radiator before removing the cap.
Hot oil
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.
