Antifreeze/coolant additive for diesels?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   It's been a million years since I've had to even think of this but here I am. Back in another life when I did diesel truck work, Ford had a coolant additive to prevent "micro bubbles" from basically acting like a ultrasonic cleaner and eroding piston liners (as I recall)
Anyhow, I've come into possession of a few diesels (one being a 5045) and all of the coolant tests at about 0*f for the freeze point across all the machines. 

So the question is, is this additive even a "thing" anymore or is any old green coolant ok to run? Not really sure which way to go but want to get whatever is needed to do it right. 

Thanks!

	New Coolant has the Additive, HOWEVER, it is a Short Lived material so the Add Bottles for the Cavitation reduction, most commonly referred to as DCA. NAPA, Ford here, sellers of Motorcraft Product lines should have it. Generic is just DCA where can Google Search that as Diesel DCA.
