I'm currently Flushing out a 2004 Solara 2.4. 48,000 miles and I believe original coolant. Had white corrosion around original radiator cap. (replaced) Ran 100% distilled for a day, now running 100% distilled + Prestone radiator flush for (about) 6 hours. Going to drain, refill with 100% distilled and run heat on high, (as I've been doing) and drain.
Going to refill with Valvoline Red coolant 50/50. Should I add water wetter or hyper cool additive, or is that unnecessary / nonsense? Car has original water pump, so anything that helps prolong the life of that I'm in favor of....
