Diff drain bolt exact size Elan S2

Not a specific answer to Lou's question I'm afraid but good background on sizing

Interesting to note the one size down change in head size during WW2 that would suggest 1/2" spanner for 3/8 thread.

I like Rohans suggestion of changing to internal hex plug for drain plug if regular use is likely.

Filler plug, 7/16 BS 3/8 W exact
Drain plug, not so easy 13.5mm across flats but my 3/8 BS 5/16 W ( high quality ring spanner ) slightly loose fit.
All plugs in excellent condition.

Only mentioned spanner as I have limited size Whit in both socket and spanners, Whitworth sizes are quite hard to find these days so you may have to settle for what you can find but I would not buy or use an open ended spanner on these plugs. Ring spanners are good in a confined space, available in low and deep offset, short and long series.

So does this item change to another item at any point in Elan history? After reading this, I wonder what I'll find on my car...

Richard, I thought my tongue was firmly in my cheek but apologies for any offence I may have given.


Lotus screwed fittings can be somewhat puzzing at times and a full set of spanners and sockets for every different pattern of thread is useful. I don't understand why it should be that a bolt head should be a different dimension, across flats, than a nut on that bolt (that's the Lotus way in one of two locations). Don't ask me where- I forget!

Did the Brits invent the shifter spanner and also the Stillson?

Thank again for all the info.. I have grinded down a couple of MM spaners and will go that route. I tested them and they are a tight fit.. Plugs are easy to open and will drain and then fill with Red line GL5 75W90 to replace the Shell synthetic in there now...

Stillson lived in Cambridge Massachusetts and got his patent in 1869.
