Jay Leno uses it on all his cars that have any aluminum content (ie, heads, blocks, radiators). He showed how a part of his was eroded on the inside but you'd never know it on the outside. That convinced me years ago to run it on my `64 GTO.

As for installation, just use their flush and follow their procedures. It's annoying, but it works as long as you can drain your block (ie, get at the drain plugs).

What I liked is that the Evans lasts virtually forever, so even when I worked on the car, I removed and reinstalled it. And what I REALLY LIKE is that it has a boiling point of 375* if memory serves me, AND runs at a much lower pressure. Those two factors gave me peace of mind that I would be very unlikely to blow a hose or something should i get stuck in some bad traffic on a hot summer day.

I plan to switch my 347 over to it soon. (Alum heads, alum rad).
