Hi all
Long time Rangie & Disco owner but new to Freelander 2 TD4.
Needed to change the thermostat (not only stuck but somehow mangled itself) and now want to flush and drain the system.
But the radiator drain tap is blocked - nothing comes out in whatever position, have poked and probed - so looking for advice on how to unblock.
Worse, I have mucked around for so long I can't remember which way is off - horizontal or vertical. If I can't unblock, I'd like to at least know the tap's turned off!
Help gratefully appreciated.
