Hi Scotty,
I contacted you not too long ago about my issue with my heat.

"Hi Scotty,
I have a 2009 Jeep Grand Cherokee Laredo 3.7 V6. The car is running perfectly fine except the heat.
I got the water pump replaced, thermostat, blend doors, evac, heater core, and radiator cap replaced. My coolant level is perfectly fine.
The issue that I am having is that the heat is not consistently hot... the heat only gets hot when I am either accelerating or on the highway cruising or revving the engine. When coming to a stop or sitting in traffic, the heat starts to blow cold. I called the dealership and they said that I needed a heater core and radiator flush.
I live in New England so it's starting to get cold.
What do you think?
Thanks,
Christian"

UPDATE: I changed the water pump to an AC Delco brand with a metal impeller and put the correct HOAT coolant in. The heat did get better but still at idle it does not get hot. I remote start my car everyday for about 20 mins and I feel that the heat is cold even though my coolant gauge is reading 150-200 degrees. The heat is only getting hot when I am driving it but, when i stop the heat stays relatively the same.

those have really crappy heater cores. It's one cow of a job replacing that heater core, but odds are it is needed now
