acf said:I talked to a local shop I use and trust today. They said they would do the flush for $89.95 as opposed to Toyota's quote of $138.95. I mentioned I would want to bring 2 gallons of Toyota red with me for the job. The guy told me what they use is identical stuff (Valvoline) I believe. Any reason to pay more at the dealer?
I went to a local shop that did it for 89.95. (Jiffy Lube) They used the green stuff. Then, when I went to drain some out to add some Water Wetter:

I noticed it was still mostly red after they were done. I'm not sure what the difference is between the Toyota red and the Valvoline green. Does anybody know? ("They're just different" doesn't count).
Anyway, I'm thinking about getting my money back and buying one of those little Prestone kits where you tie into the heater hose, and doing it myself. I've had pretty good luck with those before, but since I just bought this I figured I'd get it done with a commercial system.
Also, since water is a better coolant than antifreeze, I'm mixing it at 25% antifreeze, which should give me better cooling and protection to, I think, about 10 deg - good until the first freeze, when I'll boost the percentage. Comments?
