Greetings Everone,I'm stumped!I bought a 1993 Chevy Lumina 3.1L 164,000. It started overheating so I put N ew Radiator,Water Pump, Thermostat,Hoses,Coolant Bottle. When we drive the car no heat until I bleed the system,but only for awhile.The Coolant Bottle gets almost full,hoses swelled up, yet no idiot light comes on and the diagnostics say no trouble code found.The Anti-Freeze gets pushed out of the motor and fills Coolant Bottle and won't go back into motor,even when it sits overnight.Anyone ever have a problem like this? Any help would be greatly appreciated. Thank You,BUS
