Cockpit heat discovery

[sjuengst]

Notwithstanding the 3000's reputation for heat in the cockpit, I thought mine was unusually bad. Driving two miles would result in a uncomfortably hot cockpit. It felt like hot air was blowing directly on my legs! Well, I finally found some time to poke around under the hood and discovered that the fresh air hose had disintegrated directly over the exhaust manifold. It was sucking the hot air right off the manifold and blowing it straight onto me! That explains it.

A new hose is scheduled to arrive today, so I hope my next drive is more comfortable.

PS: I also have some EZ-Cool insulation to install, but that'll be a rainy-weekend project sometime in the future.

Well Stu, looks like you discovered your problem. Another common source of heat in AH's is from around the transmission tunnel to firewall seal. If not aligned properly it'll melt your socks.

Talking about the transmission seal, I have one where the rubber is separating from the metal frame. What's the best way to reconnect it?

Also check the door seal. there is a force of air that comes through there if the seal is not good.

A great way to check the entry points for heat is to remove the carpets from the driver and passenger floor and the carpet on the transmission tunnel. Then take a drive. You will be able to feel the hot air coming in through any holes or gaps. An assistant would be helpful.

When I did this several years ago, I was amazed at how much hot air came through a small gap between the transmission cover and the floor boards. A couple of small cubes of foam insulation stuffed in these gaps made all the difference.

Dryer vent hose was paper thin white plastic crap woven with wire. We went from bad to worse and were none the wiser for doing so.

I used a lazer temp gun with digital readout to take temp readings after my car was good and warm. With bare metal I read 132 degrees at the foot well, drivers side. I installed the insulating product that Patrick refers to above and it reduced the heat by 15 degrees. That product also did wonders for reducing engine and road sound as well.
