Have a 2004 996 tt, getting ready to drop engine/tranny for 60K kilometer maintenance and to repair a few problems. Wanting to drain coolant...is there a central plug or hose I can pull to drain the entire system? Any input greatly appreciated.

 

for engine drop, loosen off the two drain screws on engine, and remove the two main hoses by transmission tunnel.....but there always seems to be more...

 

No problem finding the hoses but where are the drain screws? Right...there is always more :-)

 

right beside the most back-facing header tube...allen head screw

 

Great...thank you. Sure that once I get into this there will be plenty more questions.
