2009 JEEP GRAND CHEROKEE engine overheat

WARNING!
•The warning words DO NOT OPEN HOT on the
cooling system pressure cap are a safety precau-
tion. Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or remove
the cap to cool an overheated engine. Heat causes
pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the
pressure cap while the system is hot or under
pressure.
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposalrules for your community. To prevent ingestion by ani-
mals and children, do not store ethylene glycol-based
engine coolant (antifreeze) in open containers or allow it
to remain in puddles on the ground. If ingested by a
child, contact a physician immediately. Clean up any
ground spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the engine coolant (antifreeze) level is
adequate. With the engine idling, and warm to normal
operating temperature, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap, unless checking for
engine coolant (antifreeze) freeze point or replacing en-
gine coolant (antifreeze). Advise your service attendant
