So I don't need that pink Dexcool? Someone recently told me that the green
stuff has a chemical reaction with aluminum, which is why I was asking. Not
true? Thanks clevere.

The green coolant has been "aluminum compatible" for quite a while. I'd
agree with clevere about the choice of antifreeze. Even if you used dex,
you would probably still change it every two years anyway....so why
not just use the green coolant and avoid any of the associated problems
that come with dex.

Thanks for the clarification Ian. I actually found a slightly higher priced
type of Prestone today at CTC which stated that it's "aluminum compatible".
It's green Prestone as well and only two bucks more a jug so I'm going with
it.

I've used the green in my 90 olds, 87 chevy cavalier, and my 94 grand prix.
All with aluminum heads .. never had any trouble with the cooling system.
(well, minus a heater core, but it was the plastic hoses that failed, not
the core itself). I wasn't even aware green used to have a problem with
alimunum heads.

The stuff you have used is probably aluminum compatible....it has
been for years. But before that.....yes, there was a lot of problems
with aluminum getting eaten away by corrosion.
