As a quick and dirty diagnostic on ECT fault, when next experiencing hard starting, fully depress accelerator. If it starts right up, that is suggestive of ECT issues. When ECT malfunctions, it over enriches mixture on starting so you have, in essence, a flooded condition. Depressing gas pedal adds more air to the mix to compensate for the flooding.

My 2001 S60 uses a 19mm wrench. Due to the wire, you wont be able to get a socket on it. The thermostat housing changed somewhere between 01 and 03 on the S60, on the 2001 I removed the top of the housing to get enough access to fit the wrench. The later model has a body that is not intended to be disassembled, but the ECT sensor is lower and looks to be more accessible

Would you guys recommend also replacing the thermostat since I already have the housing removed?

You could use either an open ended wrench or a special line wrench that looks like a closed box wrench with a slit cut into it.

I watched a video on this and he used a 3/4 open wrench to bust it open. 3/4 in = 19.05 mm so I'm guessing its a 19mm

If you wanted a socket style, you'd have to get a 19mm O2 sensor socket . That's a socket with a slit cut up side to accommodate the wire

By the way can anyone shoot me a snapshot of where the ECT sensor is?
purple - ECT
red = thermostat (thermostat housing removed)
