I've read some people say to double up the gasket when replacing. The S60 has been dumping coolant on the passenger side of driveway and its dripping on the front side of the oil pan by the oil filter. All my hoses are good and visual inspection of water pump area looked good. I assumed it must be the gasket so I replaced it today as well as the the little hose going from the T-stat housing to the cooling loop under the intake manifold. I had to use some strength to get the 3 bolts broke. I torqued them fairly tight, but not crazy because of the aluminum and did it evenly. I'm still leaking coolant enough that i cannot let the son drive 25 miles to work in this heat and run out of coolant. Anyone have issues after replacing this gasket. I did not use any type of additional sealant.
