You should never mix dex cool with anything else... it makes a disaster


I would check the label and see if Peak is universally compatible with all coolants, including Dexcool. There has been a lot of bad press about Dexcool damaging gaskets. But that is Dexcool, not Peak. Adding Peak might actually help.

I went to and it clearly states that Peak and Dexcool are compatible. Check it out.

I wouldn't mix ANYTHING with Dex-cool no mater what the label says.
