The radiator performs a critical function; it keeps the engine from overheating. While running, the engine produces heat. Coolant flowing through the system absorbs and removes extra heat from the engine. The coolant then passes through the radiator where it cools off and is later circulated back to the engine to absorb heat again.
If the radiator cracks, coolant will leak, the vehicle will overheat and could cause severe engine damage. Radiators also tend to clog over time. When this occurs, not enough coolant flows through the radiator leading to heat build-up, causing the engine to overheat. It is a good practice to change the coolant every 25,000-40,000 miles. Replacing the coolant will ensure it is free of contaminants such as rust or scale that can block it from flowing through the radiator and engine. It is also best to replace the radiator cap and thermostat when replacing the radiator.

Common symptoms for failing radiators:

  • Vehicle is overheating
  • Coolant (red, green or yellow fluid) is leaking
