its so much better for the environment... but so much more crap for you truck. Its called dexcool. Discover 2's use it as well. you can flush it out with a garden hose and replace it with green coolant or universal coolant

I would go with the factory recommended blue, thats just me. You can flush it out and use anything you want like hilltoppersx stated. The orange coolant is horrible and I would never recommend it. As a matter of fact I would tell your friend to replace his with green oat. I talked to someone I know in the automotive industry that works a lot with GM. He told me when dexcool goes from one extreme to another like from -10F to 200F the temperature differences actually cause its chemical composition to change. The coolant becomes more acidic and then eats away at the gaskets. Some people never have problems with dexcool because they live in warmer areas. For people in areas that will get below 0F in the winter, the problem will show its ugly face. The gaskets in RRs specifically the rover v8 tend to be weak anyways and having a more corrosive coolant definitely does not help.

Eats away at the gaskets! Wow! I will tell him that he has been lucky so far. He does have slight moisture around the gasket at this time but the truck is almost at 100k, which I think we would all agree it is amazing for a head gasket to last that long. I will tell him his choices are "green oat" or the factory recommended "blue" coolant. Thanks again for comments and advice!
