Engine Coolant Specifications: Description: Maintenance
WARNING: This page is about a different car, the 1988 Pontiac Grand Prix, 1988 Oldsmobile Cutlass Supreme, 1988 Oldsmobile Cutlass, and 1988 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
Periodic maintenance is necessary for extended cooling system and engine life. Because engine and cooling systems are made of different metals, electrolysis begins to destroy the metals. Changing the coolant at scheduled maintenance periods reduces electrolysis and removes sediment. See COOLANT REPLACEMENT SCHEDULE table.
NOTE:
Approximate capacity figures are shown. Capacities may vary 15% due to system variations.
