I asked my GM engineer buddy his opinion coolant... he gave the typical engineering answer, "...I prefer to stick with the OEM parts because the car was designed around them for a reason." I held my tongue, but my thoughts were, "...yea, and these were the same engineers who designed the faulty intake manifolds and window regulators and ....."

I use the "universal coolant" in all the vehicles I drive or maintain. It'* also the "long life" coolant, but I'm not likely to leave it in that long.

i use dex-cool....refill with dexcool...i like it alot more than the green junk...could not explain why....

i would say keep it simple....use dexcool...it may be expensive as hell, but its ORANGE! they haveta charge yah more cause its so COOL LOOKIN!

I totally think you should go with the universal stuff. I got rid of the Dex a couple months after buying my car (over 2 years ago now) and haven't regretted it yet. I put in regular green stuff, but definitely go with the universal. Especially since they're gonna have to drain it all out anyways....

Oh, and don't pick a coolant just cause it looks cool. Just giving you a hard time wjcollier! :P

I'm not sure what color and properties the universal coolant has. But I like the orange stuff since it is UV reactive and that has helpted me find my leaks in the past.

The long life Dex Compatible Prestone is the way to go.

It looks just like Dex to a mechanic that likes "stock only" parts.
It has better properties

I use only the Prestone Long Life Orange coolant in all my vehicles.
I don't wait 5 years and usually change it every 3 years or sooner.....and that is usually only 30 K miles.

Okay...so here'* a question... if you have Dexcool.... and you want to change to Preston long life orange ....do you have to do a total flush to avoid mixing the two? Or are they compatible?

Now...granted...I realize that the purpose of changing your fluid out is to flush out all of the old fluid and put in new....however... I'm wondering if it will do damage to mix the two? When I tried to buy coolant to top off with...I was sold the other Prestone universal stuff...you can add it to both the Green and the Orange. Didn't make sense to me...but they supposedly didn't have anyting else.

no need for a flush, add it like it is dexcool.

i just bought a bottle of the universal long life because advance didnt dtock any dexcool, my cars been running hot recently so im hoping some fresh coolant will fix that
