DOES ANYONE USE A RUN STAND?

I prefer water. You can always pull the drain plugs out of the sides of the block after running it to completely drain it. Some people use a pressure regulator on a water hose set to 10 psi or so and a thermostat. But nevermind.... you're in Ontario... Coolant! Does 50/50 even work there or do yo have to run 60/40 or 70/30 ratios? I imagine you see more below freezing temperature than you do above freezing. BRRRRR!
