So I got the truck studded and egr cooler delete and a new oil cooler. Guy who did the wotk just flushed out old gold coolant and used green coolant. I wanna get that crap out asap! With having a new oil cooler should I even use restore or vc9? I dont wanna plug the new oil cooler up. Truck got work done at 88k have 94k now. Can someone please help? Thanks guys!

Absolutely use the restore and restore+. You are changing coolant types that have very different chemical compositions. That requires that both chemicals be used.

Understood thanks! But won't that release solids that could plug the oil cooler?

Maybe, but leaving that green coolant in there will eat the engine from the inside out (cavitation). Very very bad choice for the 6.0
