I'm having an issue with the passenger floorboard getting extremely hot. I have been knocking down the rust that formed underneath the wet carpet. I ground it down and put some rust killer on the floor board to kill the rust, and now the interior smells really really bad when driving and the floorboard is extremely hot(which is burning the rust remover)!! the muffler and cat is right there and I was wondering if anyone has ever noticed the heat(worse then the tranny hump) or am I having cat and muffler issues? I am wondering if a heat shield of some kind will help at all...

reason for major concern is I'm about to rino line the inside and if the heat gets through that then toys or other things that fall on the floor board will become hot and possibly burn the kids. I'm was in another thread talking about the heat, but that was about the hump and this is a bigger concern then the heat from the hump since my kids set back there....

 

im wondering about this to,as i like to bring a group with me when i wheel and i've had complaints about the passenger side heating up very bad. I thought about wrapping it with exhaust wrap but it will get soaked when wheeling and maybe rust out my exhaust???

 

I have never had a problem with heat from my exhaust,there should be some room between the pipe and and floorboard. How much of your floorboard is left? Have you thought about replacing them? Adding a heat shield would help.
Is your jeep running good,your cat will run hotter if you have alot of unburnt fuel. It sounds like your floorboards have gotten thin and not able to act as a sheild.

 

she's running good, but yea there was a lot of rust there in a large area, but it didn't take much to remove it. I'll check on the unburnt fuel though maybe some new plugs... and for replacing the floorboard how do you do that? I just don't get the replacing part other then cutting it all out and welding new in which is OOTQ for me since I have no welder. And I have a drop kit in for the tranny so that makes the exhaust even further from the floor board. I really have to get this fixed as I have never had a floor board get this hot before...

 

You can get new floor panels,I replaced them in my 72 and just as an added protection,I fiberglassed the inside,with fiberglass material and resin,i layerd it 3 times,it will never rust again.
A quick fix would be heat shields. Contact your local muffler shop and see what they recommend or suggest for a good material to use.

 

I'll look into getting those replaced one day, but for now, I had a guy here at work that races give me some more info, and yea it does sound as though I am burning fuel in the pipes. when I first start up the jeep when it is cold it sounds like a train, kinda a chu chu chu sound as if it is in the water. then after it gets heated up it doesn't sound like that anymore, it clears off and sounds fine but that is when the muffler starts getting really really hot. so it looks like I have unburned fuel from either a leaky valve or bad plug. I'm going to check the plugs tonight and then start a fuel treatment regiment.

I don't want to start a war here :-) but I never have ever used a fuel treatment, and will look at the net to see what is recommended, but what are some that you guys recommend that will help, or hopefully help, clear up blowby on a valve?

 

I read here where some use seafoam,I have never use it. I have used lucas,not sure how much it helps. Blowby does not come from your valves,it comes from bad rings,you maybe able to reduce blowby with an oil additive,but the only way to get rid of it is rebuilding your motor.

 

sorry about that, not blowby, but a leaky valve or stuck valve do to crud not allowing the valve to seat properly. yea I have seen some talk of seafoam on here, I'm going to look at it all here in just a few to see who is better for the money...

 

Not trying to bring back the dead with this thread but honestly noticed this with mine today. I have a leaking windshield and had been getting water in the passenger floor board so I put a towel under the floor mats to help soak up some water from a storm last night. Well, on my way back, had been going for about 4 hrs, my girlfriend asked if it normally got that hot on the floor boards. I felt and it was quite toasty. I pulled up the towel and floor mat and it cooled off a bit, but the bottom left corner of the floor board was still getting warm...the part closest to the center console.

So was wondering if you found out anything about yours or if anyone else has any insight or if it being warm there is that big of a deal. I looked up under it and it's def. right about the exhaust routing so I'm sure that's where it is coming from, just didn't know if it should be able to be felt from inside.

Thanks

 

is it right above the cat? do you smell sulfur? if so, your running too rich or your cat is no good(sulfur smell.) if its too rich, i think that means you need a new o2 sensor.

 

No, don't think it is...but I could be wrong. It looked like it was right about where the exhaust tubing wrapped around the transmission before heading to the back.

 

I had this problem in the rear passenger seat. There was a rust hole about the size of my finger which caused the carpet to catch fire while trucking down the highway towing a trailer. I replaced the rusted floorboard with new steel, but it gets too hot to touch in there. After a 3 hour drive, the shifter **** will be extremely hot to the touch. I've been wondering if I was missing a heat shield.
