Anti-Freeze Concentration
WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 1984 Plymouth Turismo, 1984 Plymouth Reliant, 1984 Plymouth Horizon, 1984 Plymouth Gran Fury, and 1984 Dodge Rampage. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
On models using aluminum engines or cooling system components, refer to Owners Manual for anti-freeze requirements and recommendations. Aluminum components require a different formulation of anti-freeze to prevent corrosion.
On all cooling systems, test anti-freeze concentration using anti-freeze tester. Tester should have a temperature-compensating feature, as failing to take temperature into consideration could cause an error as large as 30°F. Follow tester manufacturer's instructions for correct use of tester.
