Sump plug diameter

[claude van rouge]

Could anyone tell me the diameter of the sump drain plug as I will need some new copper washers at the next oil change (if not before ) - these are to fit a 1990 1198cc engine.

old pre 79 stuff had 18mm copper washers with 10mm sq drain plug
more modern renaults went to 16mm washer 8mm drain key size
must be changed every time as drips if not , as you have discovered
16mm is also used on peugeot and citroen cars (and most factors sell in small packets listed as such and only list renault on the 18mm packets !!)

Thanks Paul

Yes we were getting a few drips from Claude after the oil change. But don't tell P&O Ferries it was us :wink:.

Our local DIY store in France sells them in a wide variety of sizes (they must all do their own oil changes over here )
