I'm driving a 2003 Corolla with 65k miles and the coolant needs replacing. I've heard good things about the Zerex Asian mix. My question is simply this: is Zerex Asian mix compatible with the Toyota Red that's currently in my vehicle?
My current strategy is to "flush" what I can by draining, adding, mixing, and repeated for a few iterations until I get about 88% new coolant in the system with 12% of the old red mix hanging around. Will the small amount of remaining Red be compatible with the Zerex Asian?
For reference, I posted near the end of this thread with my planned course of action. While I may pay more than absolutely necessary, I've heard that Zerex Asian lasts longer than Red and is more comparable to Pink. I can also get the Zerex locally for $14/gal.
