Cooling system

Your vehicle will have either traditional coolant or long-life coolant, and each comes with a different change interval. Traditional coolant should be changed every 24 months or 48,000 km; long-life coolants should be changed every five years or 120,000 km.

When flushing the cooling system and replacing the antifreeze, you should also replace the following components: 

  • The thermostat, which regulates the flow of coolant from the engine to the radiator. This ensures the maintenance of proper engine-operating temperatures. It also assists in warming a cold engine and passenger compartment.
  • The spring-loaded pressure cap, which raises the fluid’s boiling point. A cap that can withstand 15 psi will raise the coolant’s operating range by 7oC.
  • The hoses, which should be replaced every three to five years, regardless of how they appear on the outside. Antifreeze/coolant chemicals break down hoses from the inside out. Replace coolant hoses in pairs.
  • Hose clamps, which should be replaced any time hoses are being replaced.
