Where are the engine block drain points on an S2? Also, where is the high point air bleed screw on an S2?

If they are the same place as on other 944s, I haven't been able to locate...

I'm replacing the coolant with another brand, and I'm trying to get a fairly clean flush through.

Edit: Ok, I think I've located the high point bleed screw, but I still can't see the the block coolant drain point. Maybe you have to see/access from under the vehicle?

Edit 2: The FSM says "there is no drain plug in the crankcase from Model 89." Does this also include S2s, or are they only referring to the 2.7L NAs?

And anyway, if there is no drain plug in the crankcase, how are you supposed to an effective drain and flush? Lots of fill/empty cycles, running the car up to temp to get the t-stat open?

FWIW - I've always drained my S2 by disconnecting the lower radiator hose at the radiator (easy). Might not get every drop from the block, but it is the low spot outside the block.
