How does a radiator work?

Constructed with slim, hollow channels, the radiator sits at the front of the engine of your car. Liquid coolant is pumped from the radiator through tubes to the running motor, where it draws off the heat and cool down the engine’s components. When pumped back to the radiator, hot coolant is then cooled by air passing through the grill as the car moves. The coolant then cycles back through the engine to repeat the cycle and keep the auto systems working at an optimal temperature. It is important that the engine cooling system is properly functioning. Basically, without a radiator and engine coolant, your engine will overheat.

How to flush a radiator?

First, let your engine cool completely, jack up your car, and drain the coolant into a container. Then flush the radiator with a hose 3 or 4 times and refill it with a water and coolant mix.

How to fill a radiator with water?

You can purchase pre-mixed coolant, or choose to mix it yourself. Fill the reservoir until it is an inch above the “full” line, then start the engine. As it warms up, the thermostat will open, allowing coolant to flow in. As the coolant level drops in the reservoir, continue to add to it. Add the mixture to the radiator or reservoir until you reach the maximum suggested capacity.

How to drain coolant from radiator?

Open the petcock and drain the coolant into a container. Locate the petcock on the bottom portion of the radiator. The petcock often looks like a spout with a valve you can turn to open it, and it should be on or near the bottom of the radiator to allow it to drain. Once you have located it, make sure the container is positioned properly beneath it and open the valve.
