I run Orange OAT coolant, otherwise know as Dexcool. I know there are certain people who think that's stupid, and there's all kind of anecdotal evidence on the internet about how bad it is. However, if you look at the science behind OAT, you'd find it works very well for our aluminum engines.

Just make sure you have no leaks, and change it twice a year, and you're fine.

 

UPDATE:

Do any of you want to buy this system?

That red coolant is what they call dex-cool. It is what LR recommends for use in disco2, but most guys flush that out and switch to standard or "green"
