Here's a question for all you 390 owners (and anyone else who might know).

As you may know, it was pretty hot here in MA on Sunday. And with a black interior and no A/C, it made for a pretty hot ride! But, it seemed like there was a lot of heat coming from up front. Now I've heard that the FEs tend to preoduce quite a bit of heat, and do a nice job of heating up the cockpit, but my dad thinks that maybe the switch for the heat is broken, and it was really heat seaping out from under the dash. Anyone know who's right? What's your experience..

Another added luxury of no AC is that coolent circulates through your heater core all the time! The heater controls just turn the fan on! Enjoy the heat! I know exactly what you mean!

Yes, FE's make a lot of heat, but still you shouldn't have hot air blowing out of the vents.

There is a little valve on one of your heater hoses under the hood. This controlls the flow of hot coolant to the heater core under the dash. It should be closed with the heater knobs in the off position. The cable going to it should just slip off the pin and you can twist it manualy counter clockwise to see if it's closing all the way.

Also, make sure the firewall seals are in place for the accelerator rod, the brake pedal push rod and the clutch pedal if you have one. There is also a gasket on the parking brake cable I think. Basicaly look on the firwall side for any holes or openings and make sure they have the boot gaskets or a little filler plug there. Kory

Yeah I checked all the items Kory mentioned and it helped seal my excess heat off. You might check any slots/holes in your steering column also. I had heat blowing through there too. I'm thinking about maybe putting a heat shield under the car on the trans hump. The exhaust pipe passes next to your right foot (driver's) there and it may help.

Ooooo but isn't it nice in the winter.............???????

I'm in CA, I yanked the heater box out. I have an electric heater I bought for $12. I'll never have to replace a heater core again. I siliconed a piece of sheet metal and bolted it to cover the blower motor hole. I glued beer caps over the 2 hose holes. I'm all sealed up.
