I'm gaining some headway with the hot air coming out of my duct work but after 3/4 of an hour it slowly starts to build up and the ducts start to get hot. I took a drive today then opened the hood and put a temp probe on the heater/air cond box:240 deg.! Less than two inches away is the exhaust manifold 552 deg.! No wonder these cars get hot inside! With the slightest air movement in the ducts the air inside must gradually work it's way into the cabin. That heater/Air cond box is like a tiny oven.
I doubt even putting foil insulation over it would do much, 250 deg is too darn hot!
I noticed my car is without the foam rubber dam around the bell housing to keep the airflow from the engine compartment going past the bell housing. Is it possible that this would force the airflow to go out of the car in the exhaust manifold area instead of under the car and help create an airflow near the heater box? Sounds a little crazy, I know but something has to get rid of this hot air. I'm even thinking about making some kind of air deflector in front of the heater box to force it down.
Anyone have any thoughts?
