...when replacing the intake gaskets this weekend, I will need to drain the coolant and replace it. I have the Dexcool...

1) reuse it? (I'm thinking not - 59k miles only, but 6 years old)

2) replace with Dexcool?

3) replace with the new Universal Coolant?

My brother works for a parts distributor - says they rarely sell Dexcool anymore...everyone is buying the Prestone Universal Coolant.

I am actually planning to go ahead and change out the coolant to the Prestone Universal already in my new GXP. In the F-body world, people and shops don't seem to like the Dex-Cool and we were very happy to see the Universal come out. I have had it in my 30th for about 2 years now and it is also in our daily driver. So might as well go ahead and convert the GXP too. That is what I would suggest...

Had to edit this as I just noticed that your Bonneville is Maple Red. Is that Maple Red Metallic? I have a good friend who has a 2000 Trans Am in Maple Red Metallic. It is a really good looking color when kept up and is pretty rare on the TA'*. How about the Bonnies?

or you can get dex-cool at any GM dealer

I agree with jr.

Its what I use and leak and re-fill with

I myself, flushed and replaced with the long life. If for no other reason that the differences in the ingredients and the long term testing Prestone has put it through.

I just switched to the regular green stuff the other day. It does as good of a job of cooling as any other fuild. No need for fancy stuff. Plus I preffer the higher frequency of change so that contaminants and other **** that reguarly forms inside can get washed out. Keeping 5 year old fluid around makes me uneasy.

No need for fancy silver bottles like you people.

you cant mix the green stuff and dexcool, so unless she cleans her whole system REALLY well, that is not an option. And the same goes for you if you wanted to switch to dexcool.

Just plain Maple Red as far as I know. I've only seen the Metallic on later modeled Bonnies - such as the 04 and 05'*.
