I picked up a remote heater unit at the junkyard yesterday. It's this one, model R-254-0 it has a 12V motor and fan attached to the back. I was thinking tranny fluid or oil cooler. But, I don't wanna end up puking fluids 'cause I rigged up something not meant for the purpose. At any rate , I'm sure this cool little box will come in handy for something, I just don't know what. So now I'm calling on the vast knowledge of this board to give me some ideas. Whadda ya think?
