XUD9T coolant drain

[alangla]

Evening,

The oil cooler on my ZX 1.9TD let go recently & has contaminated the coolant with crud. I'm now trying to drain the coolant down to flush the system out. Does anyone know where the cylinder block drain plug is? The photo in the Haynes book is next to useless.

Any help gratefully received!!

Back of the block flywheel end.
