Prestone Warns On Cooling System Corrosion Risks
A 1202 car survey by Prestone shows many younger cars from 1972 to 1974 suffer corrosion in cooling systems. Corrosion can clog radiators, insulate heat near valves, and leak coolant, risking engine damage. Regular flushing and annual replacement of coolant with Prestone II are advised to prevent rust and sludge.
