After searching the Toyota forums, I found a decent number of cases where people filled their Toyotas with phosphate free Dexcool (after using Toyota red which is silicate free but DOES contain phosphates) and within weeks to a few months, had dead water pumps and leaky radiators. I also ran across this great chart that explains in detail the various antifreeze formulas and it indeed states that "Yes, DexCools also are OATs, but these Japanese formulas are not DexCool, and the two car companies have indicated they absolutely,
positively don’t want DexCool type coolants used in their vehicles." (also referring to Honda)
Apparently the phosphates in Toyota red are quite essential if you have been using Toyota red for the life of your vehicle. I'm just gonna suck it up and bend over at the Toyota dealer parts counter for the 18 or so bucks for Toyota red. Couldn't find it any cheaper online. I don't want a dead water pump in my Corolla from trying to save a few bucks.
Is there another coolent that has phosphates but is silicate free OTHER than Toyota red?
