Hi all, I am doing a coolant flush and change for my 1988 325i but the coolant doesn’t seem to be leaving the res. I have changed the thermostat and the 2 coolant temperature sensors on the thermostat housing. I have ran the car for 45 minutes squeezing the pipes and they don’t seem to fill up. I only managed to put about 6L on 5050 mix in.
Any suggestions would be appreciated. Thinking it may be the water pump not pushing the water but hoping it something easier.
Thanks
