How do you remove the oil filter cap on a 2004 Volvo S60?

To remove the oil filter cap on a 2004 Volvo S60, first ensure the engine is cool and then locate the oil filter cap on top of the engine. Use a 36mm socket or an oil filter wrench to unscrew the cap counterclockwise. Be prepared for some oil to spill out as you remove the cap, and ensure you have a rag or container ready to catch any drips. Once loose, you can finish unscrewing it by hand.
