Power flushed about 8 months ago, just a little dirty.

I agree with everything you said here except the part about paying a GM dealer for the Dex-Cool. Get it from Pep Boys, Auto Zone, NAPA, Wal-Mart, etc and save quite a bit on the price.

I disagree. I went all over the place. Pep Boys, Auto Zone and Kragen only had Prestone Dex-Cool approved. The guys thier were telling me it's the same thing. I knew it wasn't and moved on. I won't set foot in a Wal-Mart. So I went to the dealership and got the right stuff. So what if it's a little more. My car is worth it.

Hmm, kinda surprised you didn't find the Texaco Havoline brand of Dex-Cool. I think it's in the black jug. Your thorough flushing with distilled water is exactly the same thing I do plus I forgot that I too add a bottle of Royal Purple Purple Ice. Happy Vetting!

That was what I was looking for...and I checked thoroughly and the salesman were trying to sell me prestone (LOL). Spent way more time than I should have just trying to get real Dex-Cool. I could have tried another town? The dealership was right down the street and they had the real thing. I used Redlines Watter Wetter but I've been hearing great things about Royal Purple. I will use that next time. Thanks LoneStar for the tip.

Do you know how much the dealer charges for the flush and fill service?

AZ is a great testing ground for any coolant! If it lasts there it will last anywhere.

2 Questions - First, whats the difference in Dealer sold Dex-Cool, and the Prestone made Dex-Cool ? From what I remember, Prestone has made great cooling products over the years that I've used with no problems. I've had good results with Prestone products in the past, and was considering the Dex-Cool by Prestone (GM approved). And major difference in the Prestone/GM made Dex-Cool? Kragen has it for $10.99, GM has it for $18.99.

Second question, what's up with the Redline vs Royal Purple stuff now? Redline is well known brand among racers. I've heard the name Royal purple a few times too, lately. So, anyone got suggestions on adding the Royal purple's - Purple Ice... VS.... Redline's - Water Wetter .

From what I've read about Corvettes, they suggest not to use any additives in these cars.... So, now that brings up a 3rd issues... Should we use any of these additives at all....

Thanks in advance to all the Vette fans...

I changed heads last month so it was easy to look into the old heads' water passages for any buildups as described. At 60,000 miles of Dex-Cool use the old heads were clean.
