Default E30 318is M42 Overheating Issue

I've recently completed a top end rebuild on my M42. First test drive and the water temperature sawed within 5 minutes. Shut it down and discovered the radiator to me cold. So once cold I squeezed the hoses with the cap off and the radiator isn't blocked. Then turned the heater on and the heater hoses aren't getting hot either? Sound like the water pump? I should note I have removed the thermostat for now.

jrobie79 is infamous around these partsjrobie79 is infamous around these parts

jack the front end up and put the heat on full tilt, then crack the bleeder screw...then diagnose other problems if it still happens
