Guys do I need a particualy antifreeze for my RR 4.6. Its been suggested its better to stick to a specfic type. The one in currently is bright pink and I need to top it up
It's the O.A.T.S. long life stuff and cannot be mixed with anything else. It is possible to flush the whole system and go to regular blue stuff but not worth it.
With a P38 I'd be more concerned as to why it's losing coolant
