I know most of you are saying why the hell would you want that, but I bought a triple pod off a forum member and I don't have a third gauge to put in there. Has anyone done this? It would be a super easy install and easy to check for heatsoak, bad coolant pump etc. I'd also like to measure if there is a difference in running straight water vs the 50/50 dexcool which is recommended (obviously during the summertime only).
