Cab gets hot

[GirlsLoveTrucks]

I have a 1990 ranger V6 2.9L. The cab gets particularly hot in the summer, and it feels as though heat is coming from the tranny housing under the gear shifters. I'm being told it could be my exhaust manifold, and to get it checked. My exhaust was done a year ago, and it always passes air care, even with this is it possible that it is the exhaust manifold? I was thinking of putting an insulating wrap over it inside the truck so when I go camping I'm not sweating more than I already do in this heat in a non-a/c ride. Any suggestions?

Next time you go somewhere hop under the truck and look at the exhaust before shutting it down. Make sure nothing is glowing red.

If all that is ok pull on the shifter boot and check the insulation. Tears or deterioration of the foam pad under the boot, or even the boot itself can cause a lot of heat and noise issues. When I first put my new trans in I didn't have a boot, bezel, or insulator, but I did have a 100 mile drive home in December. Had to roll the windows down because the big hole in the floor was letting so much heat in off the exhaust and trans.

Cover your windows while parked...I've just started doing this and it makes a huge difference...I try to park with the back window facing the sun and cover only the back window...if you have those opening rear windows in an ext cab pop one or both of them open also...

Have you ever driven a 2.9?

I agree.

I had a '90 with a 2.9L, backed by an A4LD and ran down the highway at 70 with the A/C blasting; it was nice. Though the tinted windows did help a bit for keeping the sun out.

I do not much care to run the AC in my bronco II. It just seems to suck so much power out of the engine. It doesn't make it undriveable, but you can just tell you are loosing something. I use it in town, but once I hit the highway the AC goes off and the windows go down.

That's odd that you have that issue with your AC. My old Ranger had a 2.9, A4LD and AC and I never noticed any difference with it on or off. Didn't seem to affect gas mileage at all either.

Well I think I need to just suck it up and rebuild the system. I think the compressor has issues.

I would definitely look into rebuilding the compressor got the ac but if the heat is coming up from the floor I would also look for the leaks in the exhaust . Mine had a muffler crack on the top and my cab floor used to get really warm on the summer in town. Just go threw your system with a fine tune comb and look for a reason. Happy hunting

A LOT of heat comes over the top of the transmission....(could be leaking exhaust or just summer heat---like the guys said even on a cool day heat will come up thru the floorboard)

My A/T has an aftermarket floor shifter and even the shifter metal gets very warm!

So I put dynamat foil-backed insulation over the whole floorboard & an extra rubber boot over the rubber boot that came with the shifter....(next I' gonna stuff the primary boot with some type of insulation foam).

it helped out a lot....but at 95+ with no A/C.....covering the floormat with ice cubes is the only solution...

It's summer time. It gets hot....just install a nice little fan in the cab and enjoy the breeze!!! Do check to see that nothing is glowing cherry red before you shut off the ignition. Do it at dark time so you can see better if something is glowing, Bro!!

I don't have the insulation around my 4wd shifter and it does let in A LOT of heat in the summer. You might check that, it may have deteriorated with age.

Mine has a 4.0, during the summer between the engine and 100+ temperatures in TX I could feel the heat from the floor. Once I installed the ac it stopped being a problem.

As usual DG is right on it. My Jeep has a Chevy 350/700r4 in it and LOTS of HOT air comes in through the shifter boot area. My shifter gets plenty hot too. And yes, I have a transmission cooler. But that doesn't help the fact it just gets hot under there. Mine has some heat shielding between the trans and floor, but it doesn't do a whole lot.
I have discovered that with the windows up, no hot air comes up around the shifter, but roll em down and the furnace kicks on. I am planning on installing a second boot upside down and securing it to the shifter as low as I can get it to seal off any hot air from coming through the opening. The dynamat stuff works. Also I think there's one called Dragon Skin that does a good job too. I need this stuff in mine, just haven't saved up the $$ or the time. Best bet would be to put it on both sides of the floor if you can. I don't know how well it would adhere to the underside of the truck though.
