How to drain the coolant from the Renault Clio IV

In this video, we will see how to flush the antifreeze liquid of our Renault Clio IV: we open the hood, and for safety we disconnect the battery (so we keep the radio code handy), then we will have to lift the car, because the operation must be done from underneath.

We open the cap of the coolant, and get a container for collecting the used liquid, which we will then dispose of at an authorized center.

We remove the hose, located under the oil filter, which will make us have an unpleasant shower. When all the liquid has drained, we reassemble the hose and lower the car. Now we have to put the liquid back into the system, and we will do this by removing the air intake duct; we will have to disconnect the electrical sheath from the duct, and detach it from the clip located under the hood stop.

Now we put the right liquid back into the cooling system, up to the maximum level. Now we have to open the bleed valve located to the left of the battery, under the heat exchanger.

If we blow into the liquid tank, the level will drop and enter the system, because we will have pressurized it. We continue until the liquid flows from the bleed valve; we close the bleed screw and then remove the one from the heating circuit, which is located under the windshield frame.

We top up and repeat the operation until the liquid flows from that bleed valve.

At that point, we can close it. We can reassemble the air duct and reattach the electrical cable. Reconnect the battery and the operation is complete.
