Take shots at this idea......, I'm sure there's something wrong with it Options

So, in the quest for some sort of damn heat/defroster I was curious if this could work.

In the really sh*tty diagram below, a coolant recirculation system that cycles coolant through the muffler to transfer heat from exhaust to coolant so it can be used with a heater core to supply heat/defrost.

I would expect that the tubing passing through the muff would need to be more than a simple tube and more likely an array of small tubes in parallel to better transfer heat.

Is this feasible or should I gently place the crack pipe down and call for help (IMG:http://www.914world.com/bbs2/html/emoticons/smoke.gif)

50/50 antifreeze and water raises the boiling point up to about 250 degrees F.

I think you'll get enough heat, but building and maintaining the system will probably be more of a pain than buying a set of headers with HEs on. You can also sell on your existing headers to help offset the cost. It might even be cheaper.

Fluid systems are hard enough when you have an existing thermostat and water pump and you're just trying to get everything working right. Something like this I think you'd have to do some work to stop it boiling over.

With my Subaru conversion, I could reliably boil my cooling system before it got to temp because one of the coolant hoses went too close to the header/up-pipe - so I'm reasonably sure there is enough heat there. But it did boil the system over. Took me a long while to track the problem down.
