Please include detailed instructions about what other parts may have to be removed to access the heater control valve and how to keep coolant from spilling. Include video and/or photo links if possible. I know you just use a screwdriver to disconnect, but getting at it and preventing coolant leak could be tricky.
How do I replace the heater control valve on a 1987 Porsche 944 turbo? on 1990 Porsche 944
To replace mine I just took the dash off and it was right behind it. Very easy fix
