A warning about Evans Waterless Coolants

If you use normal water/glycol mix, be sure to run the engine every 6 months or so. Otherwise, the anti-rust particles settle out and you can have regions that corrode. That is one reason that many classic owners like Jay Leno use Evans. You can leave an engine sitting for years w/ no concerns. Don't some of our projects sit longer than we intended? Also, parts for classic cars can be tough to come by. Anyone running an early slant six aluminum block engine would be smart to use Evans, since finding a head gasket is a challenge. Most such engines were destroyed long ago by corrosion. For me, even avoiding a $100 radiator change in my 2002 vehicle is worth using Evans. I hate corrosion and sleep better knowing my blocks are not getting rust gunky again like when I inherited them.
