Coolant question??

[dman1982]

I'm at the parts store, ran my motor specs in the computer and it says to run orange coolant, what are you guys running???

And I'm using a stock radiator

I run Dexcool in my Swap & Duramax with no problems, I would run whatever coolant your running in the F-body (Factory Dexcool).

Really you can run whatever you want if your starting out with a clean and empty block and radiator. The biggest thing is DONT mix types of coolant. They will do very nasty things when mixed. The early dex cool was a problem. Current dex cool works fine. Most vehicles are now using orange coolant of some sort because the newer coolants last a lot longer and are less corrosive to the cooling system. I generally run green because its cheaper but I tear stuff apart often enough that the coolant stays fresh. If your planning to add coolant and forget about it for a long while use dexcool.

I'm running the orange stuff now since I have the 6.0 LQ4 installed. That's what it recommends so that is what I have.

I thought about that too, but since using stock rad, and having no issues with the green stuff, sticking with it
