Keffer inc Posted January 4, 2017 Share Posted January 4, 2017 I had to drain the antifreeze to make a small, but major pain to get to, leak at the waterhousing. I'm wondering if regular prestone is ok to use? Quote Link to comment https://www.bigmacktrucks.com/topic/48237-what-antifreeze-is-okay-on-a-mack-mp8/ Share on other sites More sharing options...
gearhead204 Posted January 4, 2017 Share Posted January 4, 2017 you can use it but will need to ad dca, to it. napa or heavy truck store will have it and the test strips. I use the heavy duty coolant with dca added little more spendy but no hassle testing !

Keffer inc Posted January 5, 2017 Author Share Posted January 5, 2017 10-4, I bought something from Peek. forget the name but it had SCA which my understanding is the same as DCA? I have plain water in the truck now making sure there are no leaks. When it comes back down to ambient temp, I'll load up with that pink stuff.
