Maintenance and Specifications
Refer to the chart on the coolant container to ensure the coolant
concentration in your vehicle will provide adequate freeze protection.
Neverincreasetheenginecoolantconcentrationabove60%
(protection to –60°F). At a level over 60%, your engine could overheat
and become damaged.
If you drive in extremely hot climates, it is still necessary to maintain the
coolant concentration at 50/50 coolant and water.Donotallowthe
coolantconcentrationtofallbelow40%coolant. At a concentration
less than 40%, the corrosion protection to your engine and cooling
components may be compromised and permanent damage may result.
What you should know about fail-safe cooling (4.6L V8 engine
only)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.

If the engine begins to overheat:
•
The engine coolant temperature
gauge will move to the red (hot)
area.
•
•
The

symbol
The “Service Engine Soon”
indicator light will illuminate.
If the engine reaches a preset
over-temperature condition, the engine will automatically switch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs the vehicle will still operate. However:
•
The engine power will be limited.
The air conditioning system will be disabled.
•
Continued operation will increase the engine temperature:
•
The engine will completely shut down.
Steering and braking effort will increase.
•
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
