Coolant refill capacity

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

to Refill capacities in this section.

Fill your engine coolant reservoir as outlined in Adding engine coolant

in this section.

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%.

• NEVER increase the coolant concentration above 60%.

• Increased engine coolant concentrations above 60% will

decrease the overheat protection characteristics of the engine

coolant and may cause engine damage.

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

coolant concentration in your vehicle will provide adequate

freeze protection at the temperatures in which you drive in the

winter months.

If you drive in extremely hot climates:

• It is still necessary to maintain the coolant concentration

above 40%.

• NEVER decrease the coolant concentration below 40%.

• Decreased engine coolant concentrations below 40% will

decrease the corrosion protection characteristics of the engine

coolant and may cause engine damage.

• Decreased engine coolant concentrations below 40% will

decrease the freeze protection characteristics of the engine

coolant and may cause engine damage.

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

coolant concentration in your vehicle will provide adequate

protection at the temperatures in which you drive.

Vehicles driven year-round in non-extreme climates should use a 50/50

mixture of engine coolant and distilled water for optimum cooling system

and engine protection.

What you should know about fail-safe cooling (if equipped)

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.
