This discussion is all well and good Will, and I appreciate it alot, but I need to change my factory fill before I take a 1000 mile run to Colorado in a month and since I'm embarrassed to say (sort of) I have 220k+ trouble free miles on the OEM, shouldn't I be reasonably confident that today's Dex is a whole different deal than the early lawsuit days?
Yes, it is several times over. By 06 you were on the 3rd formula for DEX-COOL that I know of. The early formula had problems eating gaskets and was quickly changed out(yet I have worked on cars with the origanal 10+ year old dex-cool in them, and it looked good enough to pour back in. The hoses even still felt good.) I think it was around 99-00 that they made teh first change to it to help with plastics and o-rings. ALot of people also don't realize that when DEX-COOL came out there hadn't really been much long term testing done because it was so new, and it wasn't known then that the first formula would attack standard cooling system o-rings. It's safe to say that the dex-cool we get now is nothing like the origanal that had all the lawsuits. But yet just like so many still claim that all GM diesels are converted gas engines, many just can't turn loose of the past. I just worked on an 04 with the origanal dex-cool in it, and I put it back in because it looked so good still, and there was ZERO corrosion of any kind inside the engine.
