WARNING
Removing the fill cap on a hot engine
can cause scalding coolant to spray
out and burn you badly. If the engine
has been in operation within the previ-
ous 30 minutes, be very careful in re-
moving the fill cap. Protect face,
hands, and arms against escaping flu-
id and steam by covering the cap with
a large, thick rag. DO NOT try to re-
move it until the surge tank cools down
or if you see any steam or coolant es-
caping. Always remove the cap very
slowly and carefully. Be ready to back
off if any steam or coolant begins to
escape. Failure to comply may result
in death, personal injury, equipment or
property damage.
•
Always use wheel chocks or proper
jack stands to support the vehicle
or vehicle components before
performing any service work. DO
NOT work on anything that is
supported only by lifting jacks or a
hoist. Before resting a vehicle on
jack stands, be sure the stands are
rated for the load you will be
placing on them.
•
Before removing or disconnecting
any lines, fittings, or related items,
relieve all pressure in the air, oil,
fuel, and cooling systems. Remain
alert for possible pressure when
disconnecting any device from a

High-pressure oil or fuel can cause
death or personal injury.

Always wear protective clothing
when working on any refrigerant
lines and make sure that the
workplace is well ventilated.
Inhalation of fumes can cause
death or personal injury. To protect
the environment, liquid refrigerant
systems must be properly emptied
and filled using equipment that
prevents the release of refrigerant
gas. Federal law requires capturing
and recycling refrigerant.

use proper techniques and
assistance. Ensure all lifting
devices such as chains, hooks, or
slings are in good condition and
are of the correct load capacity.
