Coolant engine drain location

[funthrulens]

Hey guys, I cant find the engine coolant plug (I drained the radiator, but I cant find the screw on the right side). My car is 7/1999 2.0 BMW Z3. Here are a few photos where the plug should be (shot on the right side next to AC pump)

Anyone know if the 2.2 drain plug is round about there? No real need to know just now, but maybe one day....

This is the RealOem picture of a 1997 2.0lt Z3 engine block.
You would think its number 4 and 5......but M14???

Now why didn't I think of looking at realOEM? Doh! would be the word I'm looking for. And M14 sounds about right, you can get some fair-sized lumps of crud coming out of block drains, especially if the block's never been drained before.
