Still don't have the coolant system functioning properly. I've got some intermittent coolant temp spikes and no heat. Noticed some coolant/steam leaking from the new/aftermarket radiator cap so I replaced it with an OEM Mopar cap and the leak stopped. Thinking I might have some air trapped in the heater core I attemped burping the air out using the funnel radiator cap gizmo numerous times event jacking the front end up to but was not confident I got the air out. Still no heat so ordered a Snap on vacuum coolant filler kit. Drained and refilled under vacuum - still no heat. Thinking now I may have a bad thermostat (I'm sure the repair shop replaced with and aftermarket one) so I've ordered an OEM Mopar one. In the meantime, I've checked to make sure the three heater blend door actuators in the dash are working and they appear to all be functioning properly - (1) temp blend door (2) cabin recirc (3) vent controller.

I'm anxious to replace the thermostat to see if that solves the no heat issue. Needless to say, this is Very Frustrating!
