One thing leads to another...

I decided to get a new radiator. Then I learned about a waterless coolant that requires fully emptying your cooling system first. I got great advice here to make sure I get everything out of my heater core....which made me look at my heater core and realize its no good.

I live in Florida and really don't need heat, so for now I am just looking for a loop-around tube. I don't want to get rid of the heater box, just want the tube/pipe/hose in the box where the core would be. Couldn't find it with a quick look on SNG Barratt's page...any thoughts?

Also happy to hear any dissenting views of why this could be a bad idea.

Thanks!
