Your cooling system should be inspected annually, especially before summer and winter driving. Coolant typically lasts 30,000 to 100,000 miles depending on the type-your owner's manual specifies your vehicle's schedule. Neglected cooling systems can overheat and cause serious engine damage. The Service team at Castle Chevrolet of Villa Park flushes and refills coolant with genuine Chevrolet products, inspects hoses for cracks, and tests your thermostat. A well-maintained cooling system keeps your engine running at the right temperature. Call (630) 279-5200 to schedule a cooling-system inspection.
