Where is the Fuel Filter Located in a Volvo XC60?

In this video, you will see where the fuel filter is located in a Volvo XC60 and how to proceed if you need to replace it. As shown, the filter is positioned at the lower part of the engine, right between the left half-shaft and the sway bar attachment. To replace the filter, first, go underneath the vehicle, taking all necessary safety precautions. Then, using an 18mm wrench, open the drain valve and allow any water present to escape. Next, unscrew the housing, remove the old filter, insert the replacement along with a new gasket, and reassemble everything.
