dead heater rad on my 92 disco?

Hi all wondering if anyone has come accross this. I was fitting a new stereo today and noticed it was wet at the bottom of the stereo well, I investigated further and found drips near the foot heater vent, difficult to identify 100% if its just another bulkhead leak or from the matrix itself. It has been raining and snowing allot rescently and I have been using the heater allot so diffacult to identify. Coolent doesnt seam to have gone down. Has anyone had simaler leaks in this area or do you think its the heater rad? Thanks for the tips, Jim

Similar problem on my 300tdi Jim, which turned out to be the matrix. It was in the summer so made identification potentially easier. Helluva job as the whole dash had to come out, but if you're not losing coolant (I was) it could just be ingress of water.

Good luck, Russ
