I'll be changing out my FFR
antifreeze in the next few days. Haven't done it for three years, I think I'm over due.
I bought Prestone 5/150 (5 Years/150,000 Miles) Extended Life GM DEX-COOL approved coolant. Anyone use this stuff? The label reads for aluminum radiators, and I got aluminum heads as well.
Also I'm told to mix distilled water 50/50 with the
antifreeze.
Any advise or recommendations before I start changing fluids.
