flash,

Here's a better idea. Take you radiator to a radiator shop and have them install a copper pipe thru the top tank of your radiator to run your WVO thru. This would be an easy thing to do and wouldn't even require removing the top radiator tank. Just drill a hole in each side of the tank, poke the copper pipe thru and solder the space between the copper pipe and the tank.

This would put the WVO in the hottest part of the radiator instead of the coldest part. However it would only work when the engine was up to a temperature high enough to open the thermostat.
