Hey guys, on my e30 the heater core started leaking, when disassembling I also found out that the heater valve leaks a bit. I couldn't find some complex guide on this on youtube, so I figured I could make the video when doing the repair. As a bonus I also changed the blower motor resistor which didn't work for me at any speed. Below you can see which parts I have used and dimensions for parts you can buy in advance in the heater valve repair.
