What Antifreeze to use?

Going to dump the antifreeze in my S250 and refill it. Just wondering if its ok to use a regular diesel antifreeze, or if there is some special stuff to put in it. Thanks

If you're doing a complete coolant change, just switch to regular green. If you're just topping off the factory purple, stick with it. The two can technicaly mix, but being two different things, makes an untestable concoction.

Thanks Dan, its already got green stuff in it, so I guess green will go back into it!
