I wanted to switch my Vette to good old Prestone Green Anti-Freeze. I have the whole system drained, flushed, and cleaned. And ready to be filled with the 50/50 mix of distilled water and regular Prestone Green anti-freeze.

But I went to three auto parts stores and non of them have prestone green?!?!

All the Stores have are Prestone Orange (Dex-Cool), Prestone Yellow (is said you can mix this with Orange or Green), and the only Green the stores have are the no-name store brands.

Does prestone not make the green anymore??? Is the Yellow Prestone's replacement? Is the Yellow Ok to use???

Thanks in advance!!!

What about Zerex or another brand of green? I have no prob getting green here in San Diego.

Yellow is fine. It's their new formula and it's better than either green or orange. Go for it.

I've been using prestone yellow since it came out and had no problems.

just used yellow Prestone after my engine rebuild. Asked the guy at autozone the same question because I wanted green!!! He said yellow is it and it is better.

The new regular Prestone mixes with all colored anti-freeze.

Which color will look best on my black driveway?

Ok thanks guys...

I think the consensus is that Prestone does not make 'Green' anymore. And that Yellow is Prestone's new/regular Anti-Freeze, and that it will be fine in my Corvette.

Just wanted to know, because I am following the forum's advise/consensus that the Orange (Dex-Cool) sucks and that I should take it out of my Corvette and go with regular old trusted Prestone.

I put Dex in after haveing cleaned and flushed my system this past fall, and when I questioned it on the forum, many ppl said that I should drain and re-flush the system and go back to the old green... So that's what I'm doing. But I don't want to put the Yellow in to later find out I shouldn't have... That's why I'm asking 'before' I do it this time.

Anyway... Thanks again.

Just as important, does it taste the same? it would be a shame not being able to tell the difference between a tranny leak, oil leak and antifreeze leak.

I ran Dex-Cool for years in my 71 and had no problems at all with it. Then switched over to prestone yellow as it was readily available & less $$$. Didn't have any problems with it either. If you have fresh dex-cool in there now I don't see any reason to change it.

Yeah! And will it mix as well with cheap vodka?

I'm sure a lot of GM car owners thought the same thing until they went in for an oil change and to figure out why there was no heat only to learn that the heater core was gone, and that all the freeze plugs needed to be replaced. For most small GM motors, that's an $1800 bill. I won't take chances again, and ever use Dex.

Wasn't a problem with dex-cool. The problem was chevy trucks had crappy cooling systems that let air in. Dex-Cool + air = sludge.

In addition many shops would mix the dex-cool too weak. Works with the green stuff, does not work with Dex-Cool. It needs to be 50-50.

I personally worked on a plethora of Malibus, Cavaliers, and a few other NON-trucks...and they all suffered the same problems. All had a nasty sludge clogging most coolant jackets in the block, and even a few bad radiators.

if it doesnt leak, you are out of fluid......

Durango_Boy

That sounds dirty, and I hope that doesn't apply to too many things.

And taste best to the dog? Prestone or nothing.

Durango_Boy

What's that old stray dog remedy? Sponge soaked in bacon juice, packed tight, and wrapped in strips of bacon? I personally think it's horrible to do that...but the idea is clever.
