Coolant Leak, need advice

[dgentileksu]

All,

Just got my boxster back from one month stay in the shop for oil change, new right rear wheel bearing, clutch and transmission. (Ouch!) It drove like a dream for about a week and a half, but now I am leaking coolant! I already had the coolant tank replaced about six months ago and the rear trunk area is dry, even under the carpet below the tank.

I noticed it when the engine got to ~ 200 degrees. No warning lights, but I checked the level of coolant and found it to be well below the MIN line. Added distilled water up to the max line to get it home. When I parked it, the level was holding, but six hours later the tank is empty and there is a large puddle of coolant under the car. Before it dumped, it was dripping just in front of the right rear wheel and some steam was coming out of the right side vent.

Read several other posts with similar problems and suspect water pump. However, I want to know if a pump failure would continue to leak if the car was not running... Also did not get any engine lights or loud noises. What do I have to remove/where do I have to look to better diagnose this problem?

Thanks for all the help, seems like I just can't win with this one.
