Coolant refill capacity

To find out how much fluid your vehicle’s cooling system can hold, refer

to Refill capacities in this chapter.

Fill your engine coolant reservoir as outlined in Adding engine coolant

in this chapter.

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.
