Joy, I've had Zerex in my Van for almost a year now with no coolant probs.
had a leak develop from an expired clamp but, I digress. at the time funding
was tight for all three vehicles and Zerex was actually the lowest price and
coincidentally aluminum friendly. 80 Benz 300TD , 84 Audi Coupe GT , 85
Vanagon are at mid-gauge high point after hours of run time.��� drive

The "dex-cool" type is what my mechanic recommended - he said it didn't
matter which brand.� Zerex seems to be a brand name for Valvoline, applied
to a number of different products.� Any idea whether people are using all
Zerex products, or just the "Dex-cool" variant?
