Block coolant drains

[Lander91]

I've searched, honest! Where on earth are the block drain plugs? I'm up to 4 flushes to get the green <beep> the PO had put in the engine. Still coming out green.

Here's the full rundown of how to replace the coolant. interesting that there's no reference to the bleed port on the x-over pipe at the back of the engine. As its easy to get to ATM with the airbox off, I'm going to remove this as well as uncover the hole in the hose of the heat exchanger pipe. Ill try to bleed through the x-over port, close that, then move to the heat exchanger pipe, then close that.

Funny that this says 'clean tap water' as opposed to deionized or distilled etc. I'm using a bunch of G 12E premix.

Is this really needed ?

When I did my cambelt I drained the system by pulling the rad. Then re filled from the coolant res once it was all back together. Let it run till hot and topped it up again. It’s done around 800 miles since. The level hasn’t dropped and it runs a perfect temp. I’ve always done my cars the same way and never had an issue

Nah not really. My situation needed it as the Euro "specialist" who worked on it last time (previous owner) to replace a coolant line under the intake used some green coolant. I wanted to be sure the right stuff was in there so I wanted to get every sdrop of the old stuff out. I've managed to do this after 5 flushes!!
