Cooling System Specifications: Maintenance
WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 1985 Plymouth Turismo, 1985 Plymouth Reliant, 1985 Plymouth Horizon, 1985 Plymouth Gran Fury, and 1985 Plymouth Caravelle. However, it is still accessible from the selected car via links, so may be relevant.
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.
