How do I insert photo into forum? It won’t let me?

Hi it is version D I believe. With by pass valve on thermostat installed. It also has only the expansion tank under the hood at fro t of vehicle. I have disconnected many lines and filled with coolant before running. I will check to make sure all hoses are sealed too.
I will get pictures soon.

I’m having difficulty bleeding air from the heater circuit part of the water cooling. Engine part is ok but no heater due to air lock. Any ideas would be appreciated. Sorry I don’t speak or read German.
