Video tutorial

The video describes how to replace the coolant on the Mercedes Benz ML320 W163. The first step is to drain the radiator of the coolant; from the front of the vehicle, unscrew the radiator drain plug and let the fluid flow into a container. To aid drainage, also open the cap of the coolant reservoir in the engine compartment.

Using a cooling system cleaner, run the engine for ten minutes to activate the thermostat and allow all the old coolant to drain out. Assist the flow by squeezing the coolant hoses. Turn off the engine and top up with the new coolant.
