It is a big job in term of time but technically not difficult. The whole dashboard has to come out, the heater core is buried under it. If someone can share dashboard removal schematic, would be very helpful...

On my 2010 MKZ, the heat was not decent on cold starts, even if i let it idle for 10+ minutes. I was getting bubbling sound under my dash when rpm goes above 2000 but car starts to warm up afterwards. Yesterday I see dense smoke coming out from passenger side vents which is a clear sign of heater core leak. Heater core is for $100 bucks on dealer but labor cost is insane. Can someone provide instructions to remove dash and replace heater core?
