<< Back   Tech Tips 7 Point Preventative Cooling System Maintenance Program A car's engine generates enough heat to destroy itself. The cooling system, however, protects against damage by keeping the engine within the correct operating temperature range. That's why preventative cooling system maintenance is essential in helping to ensure your engine's life. 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: a radiator pressure cap test to check for the recommended system pressure level   a thermostat check for proper opening and closing   a 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   an internal leak test to check for combustion gas leakage into the cooling system   a visual inspection of all cooling system components, including belts and hoses   a system power flush and refill with car manufacturer's recommended concentration of coolant   an engine fan test for proper operation By performing regular checks, NARSA radiator and cooling system specialists can help motorists prevent problems, emergency repairs and/or replacements, effectively saving the consumer time, trouble and money.
