This is kind of late. But I have delt with heat issues in hard working engines for years. I have read over and over about the benefits, reduced possibilities of sitting beside the road boiling over while your engine crackles and pops with steam boiling out of the radiator. My belief is that Evans coolant is well worth the heavy price tag. Reduced chance of leaking thru the seal of your water pump, less chance of blowing out a robber hose, even expansion of the metals in the engine. It contains controlling the heat of an engine that is well over the boiling point. Over end over I have read that an engine still full of coolant is still working to keep unequal expansion and contracting of metal can be critical for the survival of an engine. I lent a diesel tractor to help a unemployed friend make a few bucks. He checked the coolant then went to work on a 110 degree day in a field. It got hot pushed the coolant out the water pump seal (must have been failing when he started with it) he continued to run it till it blew our thru the pressure cap then drove t across the field to the trailer. The engine was junk. I am sure it would have gone longer,maybe finished the day itf it had Evans in it. I have Evens in my old shaker 58 Case now for 10 years. Still clean. Still runs with the gasket intentally cut. Never added coolant, I feel it has saved me a lot as I have had to have someone else use it here since I Wasn’t able to get up on it for several years. The good is l ran it last week for 7 hrs. Yea! I plan to get a truck and Evans will be put in it. Also I won’t need anti cavitation additive in it. A win win.
