Check the engine cooling system hoses for brittle rubber, cracking, tears, cuts, and tightness of connection at the coolant recovery bottle and radiator. Inspect the entire system for leaks. Cooling System - Drain, Flush, And Refill At the intervals shown on the appropriate "Maintenance Schedule" the system should be drained, flushed, and refilled. If the coolant solution is dirty or contains a considerable amount of sediment, clean and flush with a reliable cooling system cleaner (see your authorized dealer for recommendations). Follow with a thorough rinsing to remove all deposits and chemicals. Properly dispose of old antifreeze/coolant solution. Selection Of Coolant Use only the manufacturer's recommended antifreeze/ coolant, refer to Fluids, Lubricants, and Genuine Parts for correct antifreeze/coolant type.
