Hi all. I want to connect up a bleed from the top of my radiator to the header tank to aid bleeding. However im using a Davies Craig EWP 130 remote pump to pump coolant up through the tunnel up to the engine then returning back. The bleed point I have in my radiator is obviously in a lower pressure area than if the coolant was being pumped from the engine.
An engineering friend of mine has suggested if a connect up the bleed, the pressure may be too low and I could risk sucking in air from the header tank.
If this is the case , I could potentially move the pump over to the return leg so it effectively pumps toward the top rad inlet, and therefore the pressure in the bleed area would be higher. However I would prefer not to do this if can help it.
Any thoughts on the effectiveness of the rad bleed in these circumstances ?
