a 50/50 water / glycol mix should not burn too readily. It's the vapor that
burns- and when evaporated, it's in a mix with steam, which tends to displace
O2. I'm sure you could get it to burn under the right circumstances, but in
an enclosed space, like an engine cowling, you are going to get a tremendous
volume of steam. Water expands 1700 times in turning to steam, at normal
atmospheric pressure.

If there are any pyromaniacs out there who want to experiment with 50/ 50
glycol/water flammability, please share your results with this list,
Thanks.
