The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. 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 speci-
fied for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. To prevent ingestion by animals or children,
do not store ethylene glycol-based coolant in open contain-
ers or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency assistance
immediately. Clean up any ground spills immediately.
Checking Coolant Level 3.6L and 5.7L Engines
With the engine OFF and cold, the level of the engine
coolant should be between the ADD and SAFE range on
the dipstick.
To check the coolant level:
1. Open the coolant reservoir.
2. Lift and remove the plastic dipstick from the reservoir
neck.
