S/V/C S60 Coolant Drains Where Are They?

2004 S60R. So far I found the radiator drain and the drain in the coolant line to the oil cooler. I thought there was a block drain on the front by the oil pressure sensor, but I can not find it. Where is the block drain? Are there other drains?
Thanks

I drained 6 quarts of coolant out of it, manual says it holds 9.3 quarts.

I installed a new timing belt, tensioner, idler, spark plugs, air filter and changed the coolant. I have new brake pads for front and rear and a turbo control valve to install yet.

I forgot to note the aux. belt routing before I removed it. I figured there was a diagram somewhere under the hood but there wasn't. Took me about 45 minutes to figure out it's routing.

The block drain should be on the rear of the engine towards the passenger side.

That is where I found the drain in the coolant line to the oil cooler.
