Doesn't look like GM Dex-Cool... Apparently some 'long life' coolants are yellow. This is weird as it's yellow with a green tinge in sunlight. I'm debating if I should flush and replace with dex cool or with green. My understanding is the whole point of dex cool was extended change intervals which is something I never trust anyway. |

I always use Dex-Cool on all my GM cars with Aluminum Heads and or Block, never had any problems.Last Year Complete Flush with new Water Pump, Thermostat/Housing, and All Coolant Hoses on my Aurora V8. Now the newest member my Caddy with a 2.0T 4 Cylinder comes with Orange Coolant (Dex-Cool) from Cadillac, so from my 2001-2016 Cars Orange Coolant is still around and works fine...

It looks like the Prestone that's supposed to be able to be mixed with any coolant. Think its called "all vehicle"
I always use Dex. I would probably flush and refill regardless of which you choose.

It's Dex-Cool for me in all my GM vehicles. Can't go wrong using what's recommended.
