Stock C-3

I recently picked up a stock C-3 needing very little work, but it sure gets hot inside (AC not working). What can be done to eliminate / reduce the internal heat. Do the insulation kits for the floorboard and tran-y work?

Welcome to the insanity!

Yes, insulating the floor/tranny tunnel will help. Also check out this link for more info on sealing off the passengers compartment from engine heat.

The other thing you can do is to add a shutoff valve on the inlet heater hose to turn off the hot water flowing thru the heater core during warm weather.

Hope this helps. Good Luck!

Thanks for the info,

Stock C-3

Just a follow-up : The passenger vent door - gasket was trash. Although I could not find a replacement, I took a piece of 3mil foam, cut a circle about 3/8 in larger than the door and glued it to the out side. This worked great, and sealed off the hot air coming in. I also found that the gear shift boot was needed replacement. Found a genaric boot at the auto store and replaced it. Now that these two areas are sealed off, it lowered the temp quite a bit.
