Defender coolant

Ok. Trying to be efficient i had the local LR dealership flush my rad before winter storage. I had green coolant...they flushed and replaced with a pink or orange coloured coolant. It's their LR brand. Extended life blah blah blah.
I read that this is fine for the aluminum engine but not good for Brass/copper rads. Well now. Isn't a 97 defender rad made of those very items? Original rads aren't aluminum are they? Do i need to flush this out for green coolant in thr spring? Thanks for your thoughts people.

Green is the old type.
Pink is less corrosive.

There are several threads on this. Don't use Pink. Use Green.

For what it's worth, it can be difficult to bleed the system...I ended up jacking up the passenger side of the vehicle as high as I could to get it to "burp". That was about the only thing that would get rid of the air bubble I apparently had in the 3.9 since it kept creeping up in temp. After that I was good to go.
