Summer Operation

The engine cooling system in air-conditioned vehicles must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. A solution of 50% ethylene glycol antifreeze coolant and 50% water is recommended.

Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for proper coolant selection.
