Technical 2.8 idTD Cab Heater leaking after new radiator

2.8 idTD

Cab Heater is leaking after a new radiator fit, the old radiator was leaking so guess the system was not that pressurised?, do you think by installing a new radiator it has pressurised and found a way out via the heater? You can see from the picture where the leak is coming from. Is it a big job to get to back where the hose connects to the blowers to check for leaks? Just removed the front cover to see if there is anything I can see but looks like the problem is hidden in the back of the unit.

Appears that you heater matrix has corroded and now leaks , the whole assembly has to be removed , plan a day to do it and be carefull of the many plastic parts which can easily break due to becoming brittle with old age .

There are several posts describing the procedure on the forum , when the matrix is out buy the best quality replacement [ beware as there are several variants ] available as you do not want to do this job again !!!!

Good luck .

I had a leak on the short pipe from the control valve to the matrix. Given how big a job it is to get at it, it might pay to replace as much as you can, (I did the matrix, valve and both the hoses)

Was the heater matrix, spent a day replacing it and all seems to be ok.
