Draining the coolant
1. Set the heating temperature control handle to the extreme right position, thereby opening the heater tap.
2. Remove the cap from the radiator filler neck.
3. Unscrew the drain plug on the lower left side of the radiator and drain the coolant into a container placed under the radiator.
4. Drain the coolant from the expansion tank. Once the coolant stops flowing from the radiator, tighten the drain plug.
