Coolant level warning sensor

[NicBeeee]

Hi

I noticed that I have got a small leek from the coolant level sensor on top of the reservoir bottle. Does anybody by chance now what the diameter of the O ring is as the coolant is too hot at the moment for me to check. Plenty of o rings here but I am not sure which one I need.

Thanks in advance

Nic

not sure on dia, ptfe tape on the threads can help for a while

Thanks hacksawbob, unfortunatley it is going to take more than ptfe to fix this one. Just attempted to unscrew it only to find it had been stuck together previously and not particularly well at that. Guess it is out with the soldering iron to see if I can make due until I can order anouther.

Cheers
