How is their formula different from others? My understanding is the Toyota coolant does not contain silicates. I am not entirely sure but have been told silicates tend to cause buildups and/or deteriote seals.

I'm using green prestone at the moment, and it has no silicates, etc, ad nausium.. I've been running it for 20-25k miles and see no problems at all. But.. I would prefer the OEM red stuff. The only reason I'm using the prestone is because they were out of the red when I went to buy it at a local carquest. I plan to go back to the red on the next flush. But I'm not going to use the pre-mixed. I'm going to use the older red concentrate and add my own distilled water. I'd never ever use dexcool in a yota... It's a way different formula compared to yota red, or even the prestone green for that matter. The prestone is a lot closer to the yota red, except for the color. I also never mix coolants. One or the other after doing a flush. But saying all that, I'd have to agree with him. I'd rather use the OEM red if it's available. Not that I know it's really any better, but it was designed for Toyota's, so I would prefer it simply due to that fact.

How is their formula different from others? The Toyota long life coolants are 2-EH free, silicate free, phosphate free. They utilize molybdates for cavitation protection and since their products are sold world wide, their coolants are designed to be/are very tolerant of the various water supplies found. From an anecdotal experience perspective, I can't remember a single instance of opening a Toyota cooling system and finding the trash that I do on other brands that have had comparable maintenance.

I saw it on mine, but I don't know if it was still pure red coolant. I bought the car used. But it was a mess. Lots of "precipitation". Was coating everything with a yucky sludge looking stuff. Almost to the point of gelling, but not quite there at the point I noticed it. That's why I flushed and replaced mine. But it is quite possible some space cadet mixed another brand coolant with the original red. I'm kind of thinking someone mixed coolants because instead of the usual red color, it was more of a yucky brown color. I checked it not too long ago to see how the Prestone was holding up, and it looked quite good. So while I'd prefer the yota red, I see no signs that the Prestone has any real problems being used in a Toyota. It's been about two years, and it's still clean and green. But I plan to go back to red the next flush. |
