Had a greate deal of difficulty in finding the recommended antifreesze/collant for my Jeep in the UK, in fact even one Jeep dealer I asked was using the wrong thing.
So for future reference there is only one make of HOAT antifreeze that I could find for sale in the uk.
Comma Oils Xstream G05, it makes matters worse since the material for this does not actually mention that it is a HOAT amtifreeze but it does contain the correct formulation for my jeep (a diesel btw).
Go to their web site, search for a local dealer and they should order it for you, that’s what I did.
