What Does a Radiator Do?

The radiator serves an important role in a vehicle's cooling system. Coolant, also known as Antifreeze, travels through the vehicle's cooling system, absorbing heat from the engine along the way. Before returning to the water pump, coolant passes through the vehicle's radiator. The radiator transfers heat from the engine's coolant to the outside air, which helps prevent the engine from overheating. The thermostat located under the hood measures the temperature of the coolant. When the coolant reaches the correct temperature, the coolant recirculates back through the cooling system.

Without a correctly functioning radiator, the coolant retains all of the heat from the engine. The temperature of the engine rises rapidly because hot coolant continues to recirculate in the cooling system. When the engine reaches the maximum temperature, the engine will overheat, and the vehicle will not run. Overheating can cause damage to the engine because metal can expand and warp under heat.

Symptoms of a Radiator Problem

  1. Leaking Coolant
  2. Engine Overheating
  3. Low Coolant
  4. Collapsed Radiator Hose
  5. Broken Radiator Hose


Why is Coolant so Important?

Coolant absorbs heat from the engine and dumps it through the radiator so that the engine remains cool and running. Draining and/ or flushing the coolant removes all of the dust and dirt particles that the coolant collects over time. Due to the extreme heat of the engine and the debris collected over time, coolant becomes less efficient and effective. Without coolant in the cooling system, the engine will overheat and cut off.
