Hi,
Its been a while since I have posted here because I have not had any major issues till now.

Need to replace the heater control valve on my 83 240D. The valve that controls the driver side heat is sticking badly. The part is $60 or so from my local Benz dealer. Is it a simple swap (unhook the cables, the hoses, and replace and reattach everything) or is it more complicated. I know I will loose some radiator fluid as well. This is pure mechanical, right? It is not a part of the vacuum system, etc?

Any guiddance or "heads up" anybody can give me will be greatly appreciated.
Thanks!
