Why... I don't understand these results help.

1. coolant flowing through the heater core but no air flow to remove the heat.
2. air flowover the heater core which basically is adding another small radiator to your cooling system.
3. All cooling fans running which provides more air flow over the radiator, what xyz jerry rigged when he could not properly diagnose and repair his system.
I'm guessing the 224 temp was when it was pretty hot outside driving to work.
What was the temp under the same circumstances when ambient temps were much lower coming home at night?
