My floor boards get too damn hot!

    A while ago, I had to repair the rust on my floor boards so I pulled the carpet and pad that was under it. The pad was so nasty that I took it out and didn't replace it. I guess that was a heat deflector too??

    Since then I've also gotten dual exaust so on long drives (over 40 min.), my floor just gets super hot! It makes the rubber on my shoes get soft!

    So where can I get that pad? Or can I put some kind of head shield between my pipes and floor boards?

    TIA

    I believe some of our trucks came with a shield right above the catalytic converter. It helps some (reducing it from Scorching to just burning). THe most important part is gonna be the pad between the floor board and carpet.

    You can get pads just about anywhere, if I were to do it, I'd consider something waterproof. The factory material is kinda like a big sponge

    Really? I wonder if it's something else? Do you have true duals too?

    Pookster ~ Thanks for the input. I'll probably head to HomeDepot to find something that'll work then.

    I've got true duals from a diesel (original diesel body) and no floor covering.

    Floorboards get warm, but I can certainly touch them after prolonged driving. Nowhere hear hot enough to soften rubber.

    You sure the pipes are far enough away from the body?

    My 74 K20 plow truck has bare floors so I can hose out the calcium cloride road salt--and I could fry eggs on the floor if I wanted too--even in january!. /forums/images/graemlins/rotfl.gifI have dual exhaust too,but its not very close to the floorboards,I think most of the heat comes from the tranny and transfer case in my truck--I have a tranny cooler on it too! /forums/images/graemlins/shocked.gifBut I like it hot in the cab in the winter so I dont put any mats or rugs in it--it's hell in the summer though--no A/C in my trucks!. /forums/images/graemlins/grin.gif

    <font color="green"> Yep, I have duals on my truck too, the floor just behind the seats gets hot enough that you can't hold your hand to it for more than a couple of seconds. I don't even have cats, so it's jus the exhaust pipes that are heating it uplike that. I was thinking about making a heat sheild to deflect some of the heat, but there's not alot of room in there with the duals snaked around the tranny/t-case... I have just a bare floor as well behind the seats, and only a rubber mat up front.</font>

    My 75 was miserable with the top on and bare floors. I replaced the body bushings and put a 1 inch body lift on. gave it some airflow over the top of the frame. Some mats and a door mat over the tunnel and it's not so bad now.

    yeap true duals. allthough..the pipes on my truck run UNDER the t-case/tranny crossmember and they are suppost to run above it. so that may be why.

    Pep Boys sells the replacement padding, with an aluminized heat sheild on one side. It's about $20 for a 4'x6' roll.

    The '88 Blazer I just ripped apart had a heat shield over the cat that bolted to the top of the frame rail. There was another heat shield for the muffler that bolted to the floorboard. Perhaps a walk through a junkyard could net you enough parts to heatshield most of the exhaust pretty easily. /forums/images/graemlins/cool.gif One of the 4WD mags recently did an article on wraping up most of the exhaust system with some sort of high temp insulation. It made a tremendous difference in how much heat came into the cab, but that stuff costs serious bucks!

    Don't use header wrap in your part of the world. It holds in road salt and will eat up everything its wrapped around. /forums/images/graemlins/frown.gif Most header companies state that using header wrap voids the warranty. /forums/images/graemlins/eek.gif

    If you're worried about your plug wires, you can purchase heat protection boots that slip over the plug wires. Check out the Summit catalog. I'm sure that I've seen them there.

    The stuff I'm talking about is an aluminized insulating wrap that can withstand extreme temps. I think it was developed by NASA. Just a couple of feet of it can run you $50, so it can run up a big bill very fast. /forums/images/graemlins/eek.gif But it works.
