Question about 2006 Pontiac G6
The hose going to the NEW heater core is hot, but the top one going back to the engine is cold. There is no valve to control the fluid. I have back flushed, changed the thermostat, radiator and water pump all to no avail. The door which regulates the heat is working properly and is adjusted correctly. Does anyone have any idea why the coolant won't flow through the core? If I run the engine in drive vs. over drive, some heat is felt. I've also pinched the hoses thinking there could be an air bubble. This is the second winter with this condition. Car has 236K. It's got me confused...
Are you sure there is no blockage on the return into the engine? You might try forceing some water through the return hose to the engine while the feed hose to the heater core is off so you can watch
for flow. The only other thing might be low on coolant ( air pocket ). Good luck. Neil W.
