What's wrong with Toyota OEM coolant? I plan on using this when I flush the cooling system on my '99 Camry this spring.

FWIW the only Toyota "OEM" part on my '91 Camry that I had a problem with was the Delco Remy alternator that failed under warranty; so much for my experience with Toyota/GM partnering. Given my experience with a part from "The Mark of Excellence" folks on my car, I asked that a Denso alternator be used for replacement. The service advisor kind of chuckled and told me that the ONLY alternator failures they saw on the '91 Camrys were ones that had the GM sourced unit and that they would NEVER use a Delco Remy for replacement. What I could never figure out is that why would Toyota use a US sourced alternator on my Japanese built Camry; a Georgetown Camry I could understand. By the way the Denso is still going strong 11 years and nearly 170,000 miles later (the Delco died around 30,000 miles).

I'm not saying anything's wrong with Toyota OEM coolant, I'm merely pointing out the fact that many of us are tired of Malibu coming in here and mentioning Toyota OEM parts in practically every single one of his posts. It's like a broken record.

Patman,

Thanks for the clarification. I promise that I won't mention the Toyota OEM parts that I've used.

Despite none of the cars having come factory filled with Dexcool and despite all of them having brass radiators and despite one of them having an open cooling system (no overflow bottle), I saw no hint of corrosion anywhere and fluid still looked clean and bright orange...

Ron,
Most of the warnings on the Saab BB have been in regards to DexCool attacking a certain Nylon composition, not any of the metals you're reporting on (& not even other plastics). If you look at the description of "hydrolysis resistant" Nylon 6.6 here, then look at the lists of "approved" automotive plastics here, you'll see that HR Nylon 6.6 isn't on any of the lists.
