Radiator Coolant

Just wanted to know what people think is a good radiator coolant for a 97 D-90?? I'm in the process of changing my radiator and wanted to put a good coolant brand in the system. Thanks for any input.

Regular 'ol green stuff available anywhere. Nothing special about the 4.0 - just make sure you cut it with distilled water (not tap) or buy the pre-diluted.

Normal coolant as suggested and change it more often. I used PG for a few years but saw it go brown, so back to using EG.

If you are changing the radiator, now is the best time to replace the hoses!

distilled water is not the best to you because of the lack of impurities in the water it will actually corrode the radiator much faster, now that said dont use tap lol

Distiller water is the right choice when mixing with coolant. The coolant adds all that is needed

is Dex cool something you can get at the local auto parts place or is it some special stuff they have to milk from a lactating phoenix?

I guess it depends upon where you get the tap water from? A well, City water... My well doesn't have any chemicals in it but does have more metals than city water. In the city water they add chlorine, among other stuff, to treat the water. I have always used Distilled water as an additive to cut the antifreeze with no negative results.
This from "PEAK" antifreeze site when asked the question on what water to add
"Yes, tap water is commonly used for mixing with antifreeze, however, deionized water or distilled water is preferred. Do not use water softened with salts to mix with antifreeze."
