Hi guys hope someone can help me, my 2.25 petrol has a plug with thread on the left side of the engine behind the welch plugs (freeze plugs?) I assume it is for the heater, no heater fitted. The one on mine is rusted through so I had to break it in pieces to remove it, it is about 28 mm big, can someone help me with the size and thread please so that I can buy a new one.

No idea what the thread is but the book shows it as part number 527269. Google threw up a lot of hits with wildly varying prices!

Thanks Oxides, that is al I needed, I am sure I woll be able to make a plan with the info, I hope one of our local Landy spare places have it in stock.
