Coolant overflowing - urgent advice needed

[Warpbeamer]

Hello all,
I’m in need of some urgent advice. I’m currently 2 days into week long tour of a Scotland (I live in the south of England). As I pulled into the hotel parking bay tonight I noticed coolant dripping (actually more of a short term gush than a drip) from under the engine. I’m assuming the bike/coolant got too hot and has expanded causing it to overflow. I’m also assuming perhaps this could be due to the fan not working as the final part of today’s ride was at slow speed around the town searching for the hotel, so there would have been no air cooling. I obtained more OAT coolant but I realise if I just top it up it is going to happen again. However, I really don’t want to have to abandon the trip and call on a breakdown service to take me home.
Have any of you seen this occur before and, if so, are you able to offer some urgent advice on how to fix the issue, even if it’s temporary until I get back home?

Hi. Could you recognize the place of leaking?

Hi Alex,
I could not see exactly, but it was from under the bike so I’ve assume it was from an overflow pipe.

had this problem while in Sicily in 2019;;  the Good advice i was given was,,,  check Radiator fans are actually running when bike is hot, if they are  top up as necessary but DON'T  over fill . and when you get home replace the coolant system pressure relief cap ( Radiator cap to us old unns )   --  I checked the fans and they worked ok,  so followed the advice and  TOPPED UP BUT  ONLY TO THE MIN MARK,  TH
hen replaced the Radiator cap when we got home ......   not a drop since

Radiator Cap is Part Number T2108005 and costs around £12.00.

It can be replaced without removing the Fairing -
by just removing the panels inside the front wheel arch and reacing up.

and Edinburgh Triumph, 36 Peffermill Road, Edinburgh, EH16 5LL, Telephone 0330 311 7045
seem to be the only Triumph Dealers listed in Scotland, or just across the border back into England :
Cumbria Triumph, 23-27 Church Street, Caldewgate, Carlisle, CA2 5TJ, Telephone 0330 311 7140

If you decide you need one, I'd recommend phoning first to see if they have one in stock.

Mine did the same in Spain a few years ago. Just had to keep topping up, only happened when I switched off after after 5 mins or so  of slow speed riding in 30C+ temperatures. Have changed the radiator cap, but not really had chance to ride in extreme temperatures since
