Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
to
Maintenance product specifications and capacities
in this chapter.
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 –34°F [–36°C]):
•
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.
