Well since most of my truck is now straight water since the issue I had this morning. I have been researching the coolant for my truck and find out it is the plain ethylene glycol (Green) antifreeze. Low silicate and meets requirements of ASTM D-3306 and ASTM D-4985.

 

 

My only question is because of reading about cavitation errosion issues with diesels. Is the 98.5-02 Cummins ok with this antifreeze alone or do I need to add an SCA additive to the mix??

Reading too much into it.

 

Just grab a bottle of standard green or Prestone yellow or Supertech yellow and mix it 50/50 and pour it in. No additives required.

I can live with that lol.

Yep. Regular green stuff and just exchange it every 30,000 miles or so. You should be good!
