Topping Up the Coolant in a 2007 BMW 320D E91

Model: BMW BMW Various
Part: Antifreeze coolant

The video demonstrates how to top up the coolant in a 2007 BMW 320D E91. This is a relatively simple task that can be done without a mechanic. Pull the lever under the steering wheel to open the bonnet. Then, release the safety catch to lift it. With the engine cold, unscrew the cap of the reservoir, which is on the right. Inside, there is a float with two balls: if the lower ball reaches the edge of the reservoir, the coolant level is correct. Pour the blue coolant into the reservoir until the lower ball reaches the rim. Position the float in the centre of the reservoir and tighten the cap securely.
