Whilst trying to route the 4 pipes behind the water pump on a 2009 and failing, I decided to remove the water pump to make it easier. I noticed that the rear seal on the pump was nearly out of it's seating. I'm new to Triumphs and not sure if this is a common issue but may hint at a possible cause for someone.
No clue I'm afraid mate but with a bit of luck a proper knowledgeable person will point you in the right direction
