Cooling System Specifications: Maintenance
Inspect cooling system every 12 months or 15,000 miles. Drain and flush cooling system at 36 months or 52,500 miles, and every 24 months or 30,000 miles thereafter. Maintain a coolant level of 50% ethylene glycol anti-freeze and 50% water year-round.
NOTE:
On FWD models, ethylene glycol base anti-freeze must contain a silicate inhibitor to retard corrosion due to the engine's aluminum components. Failure to use an anti-freeze with silicate inhibitor could cause radiator plugging and engine overheating.
