• 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.

How fail-safe cooling works

If the engine begins to overheat:

• The engine coolant temperature

gauge will move to the red (hot)

area.

• The “Multi-function warning light:

automatic transaxle/cooling

system” will illuminate (2.0L

Zetec engine only).

• The “Check Engine” 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.
