Water Pumps - Radiator Flush - Hoses - Belts - Thermostats - Heater Cores - Cooling Fans
The National Automotive Radiator Service Association (NARSA) recommends that motorists have a seven-point preventative cooling system maintenance check at least once every two years. The seven-point program is designed to identify any areas that need attention. It consists of:
- radiator pressure cap test to check for the recommended system pressure level.
- thermostat check for proper opening and closing.
- pressure test to identify any external leaks to the cooling system parts; including the radiator, water pump, engine coolant passages, radiator and heater hoses and heater core.
- internal leak test to check for combustion gas leakage into the cooling system.
- visual inspection of all cooling system components, including belts and hoses.
- system power flush and refill with car manufacturer's recommended concentration of coolant.
- engine fan test for proper operation.
