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.

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
