Hi all, I've had a frustrating few weeks of coolant problems, tired leaking pipes, jubilee clips and coolant dripping here, there and everywhere. Finally diagnosed/realised that the coolant hose insert into the barrel of my 2004 125 txt pro is very slightly weeping. I removed the insert (which was only just finger tight) and cleaned it up and when checking the fibre washer, it just disintegrated. Bought a new fibre washer to replace it but just wondering if I should use some form of sealant on the threaded insert, some thing like gasket sealant or PTFE tape for instance? Thoughts and advice appreciated.

It does not need any sealant or PTFE just the new washer  put some copper slip on the threads before re assembly for future easy removal  Do not go mad tightening it it does not need to be super tight to seal , just nip it up.

In case you do not know it has an allen key fitment inside to tighten it.
