    Long life antifreeze ?

    We have a 1997 , 4788 with 330 cummins we purchased last fall ,as I was changing out engine ,trans oil I noticed the anti freeze jug is the long life kind I have heard from some that it's not a good ideal to put it in older engines as the seals art made for the new formula, what's your thoughts ? Regular or long life thanks

    I would highly recommend an Antifreeze made for Diesel engines... I use "Fleet Guard" and change it now as you can start with a new time line.

      Cummins Service Bulletin 3666132-07 requires the use of a coolant meeting Cummins Engineering Standard# 14603 on all their engines. Any coolant meeting this standard, whether made by Cummins (Fleetguard) or someone else should be OK. I would recommend that coolant of different brands and types not be mixed.

      Some say that Cummins engines are not sensitive to the type of coolant used. I'd rather not take any chances, so I use the Fleetguard stuff on my boat's engines.

        I agree with Norman to use what is recommended by your manufacturer. In my experience there are several quality formulas of antifreeze to use in Diesel engines. There are probably some that aren’t so good, too.

        Though a good quality antifreeze is important, it is more important to NOT mix types or having residual types of antifreeze in the same coolant system. Many diesel coolants are colored. Some of those colors are not compatible and can gel inside the engine, eventually plugging internal components of the engine, transmission coolers, turbo coolers, etc, etc. In some cases it can damage internal components. I haven’t had such issues, but I have known of a couple people that have had coolant issues eventually finding it was caused by them basically just using whatever in thier engine, accidentally mixing incompatible antifreezes.

        I am told that if you flush the system really well, you can use whatever antifreeze you choose without any issues. In Omega, I use the Red, Zerex Heavy duty extanded life Antifreeze. It’s a great antifreeze. I use this in all my antifreeze applications on Omega,

        i hope this helps,

          ZEREX Extended Life is an example of an aftermarket coolant that meets Cummins Standard 14603:

            If you have some reading time...coolant section starts on page 16...

            I found this while researching fluids for my Cummins...maybe there will be some important info for you for coolants...and other fluids...

            I think one of your questions is dealt with directly...

            Hope this helps...

              I have a 1988 3288 with 135 turbo hinos' How often is the anti-freeze suppose to be changed? I went through a big ordeal a few years ago by using the wrong color antifreeze. Flushed my engines out as best as I could and have been using this Prestone product ever since, designed to be used with any color antifreeze.

                Hi bcarli

                I would use an Antifreeze that meets the needs of our Hinos...not sure that "Preston" does.even at that I still change mine every second year using "Fleet Guard".
                i know Earl Summerville (the Hino guru) uses the NAPA Antifreeze as posted above by Pete.....Just my 2 cents worth.
