Bypassing the heater control valve E38 740iL
The heater control valve/pump assembly on my 2000 740iL has developed a catastrophic leak and I have ordered a new replacement from US based supplier FCP Groton (I am in Australia) which will take about 7 – 10 days to arrive. I’d like to keep using the car and I thought that I might be able to do this by removing the pump/valve assembly from the cooling system path by connecting a length of generic heater hose from the engine supply side (normally goes to the heater pump) to the return point on the engine. Obviously there will be no warm air for me during this time, but the car would be on the road.
Do you see any issues with this idea, or do you have any other suggestions?
