How Does a Car Radiator Work?

Your radiator is responsible for keeping parts of your Subaru model cool -- but how does it work? First, the thermostat on your vehicle's engine will sense the extra heat. Water and coolant are released from the radiator and go through the engine to absorb the heat. When the liquid picks up that heat, it heads back towards the radiator. It'll blow air across it and cool it down -- this heat is exchanged with the air outside your Subaru car.

What Are the Symptoms of a Bad Radiator?

Keeping your radiator in good running condition is a must. Think yours might be failing? There are warning signs that may indicate yours may need to be replaced or repaired. These signs include:

  • Your vehicle is leaking fluid
  • Your vehicle is overheating
  • The Check Engine light turns on
  • Discolored coolant
  • Damaged fins
