If it’s a euro 4, don’t forget the turbo is water cooled and you have EGR cooler pipe work. Had a small leak years back on my S60.

have you left it pressurised over night with a coolant pressure tester?

Coolant system pressure test
Re pressure testing the coolant system.
If U have or can borrow the Sealey VS820 brake bleeding kit, the same cap that normally fits the brake fluid reservoir, will also fit the coolant reservoir. Pressurise the Sealey bottle and leave overnight. as Clan suggests. A slight loss of coolant I had a few months ago, was solved by reversing the seal ring inside the coolant reservoir cap. Jude
