Severe climates

If you drive in extremely cold climates (less than –36° C [–34° F]), it

may be necessary to increase the coolant concentration above 50%.

Refer to the chart on the coolant container to ensure the coolant

concentration in your vehicle will provide adequate freeze protection.

Never increase the engine coolant concentration above 60%

(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. Do not allow the

coolant concentration to fall below 40% 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.

How fail-safe cooling works

If the engine begins to overheat:

• The engine coolant temperature

gauge will move to the red (hot)

area.

• The and the symbol

will illuminate.

• 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.
