I pulled my radiator when I tabbed my KDP. I'm not sure when it started after that, but now if my truck sits for even the shortest time, idling or shut off, I will hear gurgling at the heater core when I accelerate the engine. How do I purge this air?

I do not have any overheating problems either. Radiator and overflow bottle are full. Perhaps I need to crack the radiator cap, bring the engine up to temperature, then check fluid level then.

 

OK, maybe this will have taken care of it.

I started the truck, and blocked the accelerator pedal so that the engine stayed at 2000 RPM. I opened the radiator cap and let thermostat cycle about 20 times. I kept adding fluid each time.
