Mine packed up a while ago, it is an easy fix but you need to drain the coolant (good excuse for a flush ) The genuine part costs around £30. I'll put the number on here later.
It's easy to check. Look at the position of the cold start lever on the pump and see if it has moved when the engine warms up. Quite a common part to fail.
