Reply to "Heater core - keeping it cozy"

The theory is that about 25% (4 fan sections in total, one of them fed solely by the hose) of the air moved by the fan is fresh outside air which can be directed with the heater controls to the windshield or down or whatever the flaps are set! Or 100% of whatever air is pushed by the driving speed thru the grill under the windshield with the fan off…

we will see…🤓
