I wish I had never tried to drain my coolant using the radiator drain cock, after all it didn't work and I ended up removing the bottom hose,

Ever since I have had a leak from the drain cock that, so far I have been unable to stop, obviously I have not been able to find the correct o ring size.

The leak is starting to get worse so I thought a different approach is needed.
Does any body know if the drain cock is removeable and if so what diameter and thread do I need to replace it with a blanking plug.

Local indie says a new radiator required, that sounds over the top!

If your radiator is part number LR021777 the drain plug is showing as available separately PYB500020. About £3.50. Hope this helps.

Many thanks but that radiator is for a disco 3/4 or a sport despite the description saying is for an L322

My radiator is a PCC500670 or PCC500370 and the plug is this less the o rings.
