Cooling System

Ashland Auto Service – Cooling System


It is recommended that a seven point preventative cooling system maintenance check be performed at least once every two years. This inspection is designed to identify areas that need attention, and consists of:

  • a visual inspection of all cooling system components, including belts and hoses
  • a radiator cap pressure 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
  • an engine cooling fan test for proper operation
