Heater matrix leak?
I've topped up the coolant a couple of times. Seller told me after I confronted him system was pressure tested at dealer's with no fault found, after he also had to top-up. Now as it's cold outside and I started using heater more, I notice there is a film collecting inside windscreen, which leads me to thinking there's a coolant leak inside heater matrix.
How do I access this, and how do I find a leak? Any other obvious things to check for? Oil looks normal, no wet spots on the floor...1951 Series One 80" 1600cc Deep Bronze Green

You may try to pressure test the martrix alone to double check
What about the EGR collers???
Do not be tempted to use s/h part on matrix job is too big to risk doing it again shortly after
