Lincoln Aviator: Engine Coolant Check / Recycled Coolant. Severe Climates. Coolant Change

Recycled Coolant

We do not recommend the use of recycled coolant as an approved recycling process is not yet available.

Note: Dispose of used coolant in the appropriate manner.

Follow your community's regulations and standards for recycling and disposing of automotive fluids.

Severe Climates

If you drive in extremely cold climates:

• It may be necessary to increase the coolant concentration above 50%.
• A coolant concentration of 60% provides improved freeze point protection. Coolant concentrations above 60% decrease the overheat protection characteristics of the coolant and may cause engine damage.

If you drive in extremely hot climates:

• You can decrease the coolant concentration to 40%.
• Coolant concentrations below 40% decrease the freeze and corrosion protection characteristics of the coolant and may cause engine damage.

Vehicles driven year-round in non-extreme climates should use prediluted coolant for optimum cooling system and engine protection.

Coolant Change

At specific mileage intervals, as listed in the scheduled maintenance information, the coolant should be changed. Add prediluted coolant approved to the correct specification.
