Thanks, yes I think it would be a good idea to change it, especially given your comments.

So does a guide exist? I see on YouTube there are some examples but they tend to be on older models. A Puma 2.2 specific guide would be great Very Happy

Oh, and a new clear expansion tank would be ideal if it exists ...

Most damage done by coolant is when your truck sits for a long time not doing anything.

Change your coolant at the service intervals with whats recommended and then just use it a lot in between.

Its probably rusty because someone in the past has just topped it up with normal water and then let it sit for a long time.

Drain it, Flush it out with lots and lots of clean water, half fill it with the correct antifreeze and then de-ionised water and it will be fine Thumbs Up Running Restoration Thread http://www.defender2.net/forum/post323197.html#323197

Could some one have filled it with normal water mixed with the glycol, as opposed to distilled?

Absolutely; more than likely I would imagine.

I guess this is another example of why it is preferable to undertake some maintenance yourself. You are always going to take the time and make the effort to do it properly. I am always somewhat skeptical when it comes to trusting garages, regardless of whether they are a main agent or otherwise ...
