Loosing coolant quickly around front of head, but can't quite pinpoint... 900 1995

I'm checking over the FAQ now, and as soon as the engine cools, I'm going to do some exploration.

Wife called me that the low-coolant light came on and the car was leaking coolant.

(BTW... that coolant sensor is the #1 best addition to add to a 940-series. It has saved this car a dozen times at least)

I met her and confirmed that coolant seems to be dripping out from the right side of the engine, well above and behind the water pump.

I traded her for my C70, topped up the coolant and drove the car home.
Arriving at home 30 minutes later, I found that the coolant was down about 1" from the top-off mark. Not end-of-the-world loss, but it certainly needs to be solved

I've got a stainless steel pulsair pipe that's in the way, so I'm not sure where the coolant is getting out. It seems to be forward of spark #1...

I'm *hoping* that the o-ring on the back of the water pump is the culprit, but I'm concerned it's something else... maybe the coolant pipe...


Any thoughts before I tear into it? It need to cool down a bit more before I can do much.
