Very confident my heater core went out in my 08 Pontiac g6. I have no heat, smell coolant in the vents and I'm losing small amount of coolant everyday. I need step by step instructions on how to remove the heater core. I've already started on disassembling the dash but I am unsure where to go from there. Thanks!

Yes, the dash as well as the center console have to be removed and air conditioner charge has to be evacuated as well.
