I've been working on the car this morning, apparently I didn't tighten the lower radiator hose clamp enough and have a BIG puddle of Evans under the front of the car. I bought 5 gallons, so I have enough to top off.
,,,but, it's not like you can buy this stuff just anywhere. If I have a problem on the road and have to use water it could get costly doing a flush and refill later at 30-35 bucks a gallon!
Strange thing is, I have a radiator pressure tester (pump it up). I tested the system pressure when I first finished the job. It held pressure for about a half hour. I tightened the hose clamp, pressure test again, looks OK now. What's up with that???
Perhaps OCCOBRA is onto something about how this stuff has a tendency to "leak". I think I'll run some kind of "Alumaseal" leak stop compound as a precautionary measure. I ALWAYS ran some kind of stop leak on my Jaguar V-12, as recommended by the FACTORY (it still leaked on occasion, Jaguars, Harleys, FE's, just the nature of the beasts I guess)...
