best radiator coolant ????

[Cosmic88]

Is there a particular, recommended type of coolant which should be used with the original (brass topped) radiators?

I use regular Walmart variety universal anti freeze. I change mine every two years. Most stuff out there is made for multiple metal compatibility.

You could spend more money of course and buy long life a/f. Good deionized/distilled water. 50/50 mix is the norm.

ok

That's pretty much what I thought but I figured it couldn't hurt to see if there was some double-secret formula conjured up by the mad scientists as Leyland.

Thanks for the responses.
