    Yes, to the rear of the starter motor... basically inaccessible on the latter motors - and usually clogged internally anyway!

    As others have mentioned, the drain plug is located under the exhaust manifold, behind (i.e. on the cabin side) of the starter motor (see item 4 in the attached image from the Autobook workshop manual). I think it has a 21 or 22mm head and I usually use a ratchet socket handle and a short extension (i.e. between socket and handle) to reach it. It's a bit of a contortionists act to reach and may be a bit tight on first undoing, but I drain my cooling system fairly regularly, using the radiator drain and the block drain and I have no trouble with the latter.

    Good luck.

    A big thank you to all who replied to my dilemma.
    I found the little blighter but decided to use the drain cock on the radiator.
