Check out Prestone Heavy Duty Antifreeze. It lists it as compliant with TMC RP-329. On the back it lists all the engine manufacture's. It has a purple cap. We have 2 BB that we use this on that was running the "blue" antifreeze. I long for the day's when we just had antifreeze. 50 years ago all the antifreeze's had different colors and I seem to remember some standard that changed them all to green, except Prestone which was still that weird yellow color. Hope this helps.
I would look into fleetcharge, 1 of the members says he was getting 200k on waterpumps, in the cummins . we don't have anyone around here selling it. but the factory crap they are using isn't any good anyways. so probably any good extendlife would be better than the fleetguard brand. I cant send a bus a to cummins for 2 days and pay 2 drivers to bring and pickup. for a 60 dollar pump. Have enough Cummins emissions problem buses there now waiting.
