Interior Heat

Post by Nitrate »

1981. 2000. Where is the heat being generated that ends up in the cockpit of the car. My heater valve turns off the heat from the heater core but boy it is awfully toasty in the drivers compartment . Is this heat off the block, the exhaust pipes coming off the engine, the transmission, the cooling system? I'm trying to determine the source so I can insulate at the source. Anyone have some thoughts as to where most of the heat originates that eventually finds its way into the interior? Thanks, RB

Catalytic Converter under passenger floor is a strong source. Maybe heat shields under the car are missing, etc? Also leakage of air from around the shifter is typically a major source too. AR and the various other vendors have the foam seals to tighten that up, just have to remove the center console to get at things. Not too hard.

make sure your heater valve is actually shutting off the heat.

Make sure the rubber shifter boot is not torn (not the leather one, it's below that), a lot of heat can come through a hole in that boot.

Just saw in the other thread that you've done all that. Sorry.

I can't think of anything on the driver's side which would generate that much heat. Good luck with the search!


Given the (relative) inexpense and installation ease of products like EZ Cool, I'd recommend checking the boots, per above, then adding a layer of one of the reflective/closed cell insulating products. Makes the cabin far more comfortable all year roun

The heat is not just localized to the driver's side. It's hot through the the cabin. I'm thinking of wrapping the exhaust header pipes and a section of the exhaust pipe with that header wrap that keeps the heat with in the pipe. I was hoping a seasoned veteran could highlight one or two offending areas so I could zero in on those. I've pretty much covered the suggestions so far. RB
