Evening all, quick question, how many of yall are running DCA4? or your thoughts on it.. I haven't run it in my truck yet but have always put it in the marine engine s I work on. thanks stephen

 

Per my Cummins guy....the Rotella premix stuff was just as good for our trucks and 1/2 the price at Pep Boys.

 

The coolant additives are mainly for wet-sleeved engines for cavitation protection of wet sleeves. For parent-bore engines I prefer to just change the coolant.

 

Hey Guys

I do use the precharged antifeeze ... but I also do the test strips to keep my charge with in levels ... the DCA4 is basiclly a anti-foaming agent ... it keeps the micro sphearical bubbles from acurring ...
Cavittation can happen in any diesel engine ... it's compression combustion that vibrate's coolant and the bubbles chip away at the motor from the inside out .
How ever some guys say that it never happens , I have seen a few diesel engines that have had cavitation ... The aluminium engines were far worst than the cast iron .

For me charging the system is no big deal , I do all my diesel powered toys ...it won't anything ...I think is $ 7.00 a bottle .

A year ago I called Cummins Tech Line and was told that unless I had a ISB with wet sleeves { ambulances come with them ) there was no need for additives. With wet sleeves the cavitation protection agents ( nitrites ) deplete faster and periodic charging is needed, With parent-bore engines, by the time the additives are depleted it is time to change the coolant anyway.

 

Hey guys, thanks for the views. Next question... I am getting ready to flush the antifreeze for the season before it gets to cold to work outside, and was wondering the general feel for brand of engine/radiator flush, or do yall just swap the premix out. thanks stephen

 

If you havn't been neglecting your cooling system then a flush probably isn't nacessary. You can try and peek into your rad innards by disconnecting the top rad hose and make sure the inside of the rad is clean. I would do a distilled water rinse and fill the system with HOAT coolant + distilled water. You can go with Mopar pink or Ford yellow or Zerex GO5.
