Evans Coolant
I've been running the Evans coolant in my ford for several years and have seen no down side. I run a "0" pressure system, coolant filter, and a 203 degree thermostat and have never had a problem. I'm considering changing my 05 cummins over and posted yesterday asking what type of antifreeze is currently in my truck and whether anti-cavitation additives are required, but have had no response. I changed my ford over because of the additive requirement and their negative effect on the water pump, I believe the fact that you can run low or even no pressure is an added benefit. I paid $25/gal a few years ago but I believe its closer to $35 now. Jeff
