Sorry for the pun but at least this gets me back to the top of the Club Triumph blog table!"
So this evening I have replaced the wheel bearing and the flasher unit so I think the car is ready for it's re-MOT on Saturday - wish me luck.
Mind you that top hose/radiator joint is still leaking. I still have the old hose so I will refit that with a new hose clip and see what happens. I can't see that solving the problem but at least I will have eliminated it - then it can only be the soldered joint on the radiator.
