Question about GMC Yukon
If you have 20 degrees difference that is quite a bit of a difference.i would say that the heater core is plugging up,remember the fan blowing air across the core is cooling the temp more and with a 20 degree difference its alot.you can try to run CLR through it a couple of times to see if it will help flush out more dirt.sometimes flushing just doesn`t do it.
