So we have had our Burstner for a year and the entire time there has been a leak on the coolant circuit from the engine to / from the Alde heat exchanger. The leak is not significant, worst we have had is about a cup full of fluid into the locker.
The van was purchased from Camper in Lincoln and as they are a two hour drive, they agreed to let a local firm repair. The initial leak appeared to come from the circulation pump, which was changed. However the leak now appears to come from the connection from the pump and the 90 degree elbow. The local firm has had another go this week, but unfortunately the weep is still there.
Having looked at this again today I am concerned about the condition of the heat exchanger itself. It is going green.
Any bright ideas? Anyone come across this before?
Thanks in advance.
