I am going to replace my thermostat (which I believe is a 195) with a 160* and at the same time replace the housing and the upper radiator hose with an aluminum one. I also want to drain/flush the coolant. What do you guys recommend for my climate? Distilled water and RMI-25? 50/50 coolant/antifreeze? 50/50 with RMI-25? There has been comments made that RMI-25 is safer for the motor especially if you blow a headgasket.
Thanks,
Don
