Question for anyone with an FJ40 with factory -installed AC (1 Viewer)

For anyone who has an FJ40 with a factory installed AC system (doesn't matter which model year)...
i am wondering if/what things Toyota did to litigate engine/transmission/exhaust heat within the cabin. is there additional insulation on the firewall, under the floor, etc? What about additional heat shields to deflect heat?

i have been reading all of the threads in the forum for after-market heat treatments and AC installs, and i am wondering if this was identified as a problem originally when the trucks were new, and whether they made accommodations for the trucks that had AC installed in the factory.

Good question, they are rolling ovens. I have aftermarket headers on my 2F and would love to stop any transmission of heat off that cast iron block or headers

I've got manifolds, and it is nearly unbearable, even in the spring and fall. I used a laser thermometer to check spots on the floor and hump in the driver and passenger sections and the temperature ranges from 120 to 145 degrees. I know insulation helps, but i wonder if Toyota did anything about it.

They added no additional heat proofing to the factory A/C models. I have a 40 with factory air con and it is identical to my 40 without it.

If I ever remove the seats again I will be adding some heat proofing to the front wall as on a hot day when you think the A/C isn't doing much you turn it off and you realise real quick how much it is actually doing

Great feedback. That's exactly the kind of information i need.
Its amazing how hot it gets.
Now i have to determine if it makes sense to adhere insulating material under the cab or not. I might lay it down inside the cab (not adhered), below the floor mat, but honestly i would rather have it outside the cab. And i see so many people on MUD warning against adhering it anywhere, (like inside the engine compartment on the firewall) due to a fear of trapped moisture. But all i see are warning of moisture, but no real anecdotes of it actually doing damage.

as stated above nothing different in my a/c rig.
if the windows are up and the door seals are good,just running like that it stays cooler inside.
try running with the windows up for a bit then unroll them and it will be hotter inside
