Louisville KY drivers trust Pinnacle Motorsports for expert cooling system repair and radiator service. Your engine generates extreme heat during operation, and a failing cooling system can lead to catastrophic engine damage. We diagnose and repair radiator leaks, water pump failures, thermostat problems, and coolant hose issues for European, exotic, and domestic vehicles. We use manufacturer-specified coolant formulations — BMW blue, VW G12/G13, Mercedes-approved — because the wrong coolant causes corrosion and gasket damage.
