97 Deville Coolant Type

[userpete1037]

I have one question, I know that the Deville uses the Dex Cool 50/50 but what will happen if you use Dex Cool Straight antifreeze?

[maxwedge]

All straight coolant is mixed at least 50/50 for proper heat transfer.

I wasn't aware that all coolant is mixed 50/50. Thanks.

Unless you're up on the North Pole or somewhere, fity/fity is the way to go.

[maxwedge]

It is not mixed until you mix straight coolant 50/50 yourself, some coolants can be purchased pre-mixed.

[userpete1037]

Ok. Makes sense now.

And mix with distilled water only. Not government issue or well water. Too many minerals in that stuff to clog yer cooling system down the road.
