Dauphinee Posted May 8, 2011 Share Posted May 8, 2011 Ok I finally took out the indoor carpet on my floor under the drivers and pass feet. The drivers had a nice opening to the battery but nothing covering it. Got to definately cover that. Now the pass side had a piece of Plywood that sits right above the muffler. Wow did I see some serious heat damage to the wood and rug. What is recommended to put on the bottom of the new piece of wood to stop the heat transfer??Does anyone have a pic of what type of trap door to put ontop of the battery.1936 pontiac Deluxe 4 door Link to comment Share on other sites More sharing options...
Guest WEB 38 Posted May 8, 2011 Share Posted May 8, 2011 Do you have a print shop near by If so see if they will give you one of there old alum. offset plates and apply to the back of the wood try to get as thick as they have or double up. Hope this helps.. works for me. Bill WEB 38 Link to comment Share on other sites More sharing options...
Dauphinee Posted May 8, 2011 Author Share Posted May 8, 2011 wouldn't it be easier to put a 1/4" thk piece of aluminum and then a piece of wood?? Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 9, 2011 Share Posted May 9, 2011 Was the original floor made of wood? Any sheet aluminum will reflect the heat. Space it away from the wood for best results. The muffler may be too close to the floor. Link to comment Share on other sites More sharing options...
Guest 36chev Posted May 9, 2011 Share Posted May 9, 2011 On my 36 Chevrolet, the battery cover (passenger side) was and still is originally plywood. But GM engineers were at least smart enough to have tail pipe going down the other side! Link to comment Share on other sites More sharing options...

The muffler may be too close to the floor.On my 28 Pierce the exhaust ran under the drivers side floor. All the original floorboards are wood, the removeable front ones had a thin layer of insulation underneath, probably asbestos. I made sure to replace the muffler with one the same size and shape. All exhaust components were at least 6 to 8 inches away from the wood and there was no evidence of heat damage. Link to comment Share on other sites More sharing options...
R Walling Posted May 10, 2011 Share Posted May 10, 2011 As Rusty stated, fasten the sheet of metal to the wood with at least 3/8" air space to allow the heat that passes through the metal to disburse. (Use 3/8" nuts as spacers.) If placed in contact with the wood, it would just transfer the heat directly into the wood. Link to comment Share on other sites More sharing options...
sambarn Posted May 10, 2011 Share Posted May 10, 2011 when you say damage are you refering to exhaust staining or actual burning?? most cars of the day have wood floor pans and little issue with this.. Could just be leaky exhaust staining the wood. Link to comment Share on other sites More sharing options...
jscheib Posted May 10, 2011 Share Posted May 10, 2011 I agree with Rogers coommets. Use spacers, and I think the exhaust may have been too close to the wood. After all, there is plenty of room between the floorboards and the ground on most old cars. Link to comment Share on other sites More sharing options...
jim43 Posted May 10, 2011 Share Posted May 10, 2011 This is a dangerous situation. On the night of June 4th, 1968, while on a 600 mile drive home from college in my overloaded 1931 Cadillac V-8 sedan, the car caught fire in the back. I had a heavy trunk on the back, loading it way down. Our ears were glued to the transistor radio listening to news of Bobby Kennedy's assassination. We neglected to smell the smoke. Came the dawn I could see we were trailing smoke. I stopped and then it really smoked, and wood, horsehair, and mohair really took off, burning out the entire interior and roofing before water arrived. Conventional fire extinguishers were useless. Only water worked. I drove it home the last 100 miles. Take no chances with exhaust and wood. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 10, 2011 Share Posted May 10, 2011 I used to have a farm house with old dry wooden wainscotting in the kitchen and a wood stove less than a foot from it. I made a heat shield from aluminum screwed to the wood with 1" spacers. No matter how hot the stove got you could put your hand behind the aluminum and it was cold.

Durant Mike Posted May 10, 2011 Share Posted May 10, 2011 What about muffler wrap? Restoration Supply Company out of California sells several types. I'm not sure what years it was used, but it might be the thing to use. Link to comment Share on other sites More sharing options...
