I’ve had a few issues with my 1990 320i overheating on idle. The temp goes up gradually on idle which has now confused me. I thought it was the fan clutch - made sense as temp goes back to normal whilst driving - and it needed replacing.

With the new fan clutch, the car still overheats on idle… does anyone have any ideas that might help? Thermostat is good, replaced recently, radiator good, just bled system, no more ideas!
