The heating system in the car doesnt work. The bleed screw at the front of the manifold will only put water out when you rev it up for the cooling system. If i have to bleed it every time after the car goes back to idle is it a bad water pump?

 

if the car over heats when running probably a water pump, if just the heating doesn't work try replacing the thermostat

 

I dont understand anything you are tryin to tell me other than you have no heat??
