Hey Guys,

I was going to tackle changing out the coolant in my coach for the newer Extended Life OAT type coolant. Can I use any type OAT coolant like FinalCharge? Are there any I should just stay away from? Cummins in Canada is very expensive for everything so I would like to avoid buying the coolant from them unless I have to. Thanks for your input.

Not "any type OAT" but any one which passed CES14603 standard - Final Charge, Fleetguard ES Compleat OAT, Shell Ultra, Chevron Delo Nitrite-Free OAT... Due to the different organic acid combinations they use, don't mix them. Whatever you use stay with it for refilling low coolant levels.

I got the concentrated Final Charge Global from O'Reilly's Auto Parts a year ago.

I bought the Final charge on line a year ago, case of 50/50 and 3 gallons of the concentrate. After 4 good system flushing s, I added 2 of the concentrate first, then filled the rest of the way with the 50/50. Worked out well. Don't forget to install the "Blank" coolant filter. I used DI water to do my flush's of the cooling system.

Cummins water requirements for hardness, <170PPM
When flushing, make sure to turn on the dash heat control to hot so all the old coolant in the heater hoses and the dash heater core is circulated out. Do the same after filling with the Final charge after filling..........leaving the dash heat control on hot.

I am about to replace my leaky radiator with a new copper/steel unit and am changing to Final Charge. What filter do I use? I know it will have no chemicals in it; just need a brand and number. ISC 330 2002 THX TB

NAPA # 4070 is the "Blank" filter, you can cross that number to what kind of filter you want to use, here is a Fleetguard filter WF2077

Thank You! Just the info I needed. Picked up the new radiator today; the work will begin soon. Unfortunately, I will not be able to flush the system until I install new rad due to freezing temps at night here in the great NW. Wish me luck! THX TB

OP - First post? Welcome to the gang!!

And X's 2 that Final Charge is a good choice. I took the advice of another Country Coach owner, when he pointed out that it's more likely then not, to find Final Charge available at truck stops.

Another tip, that I followed, was to have the radiator also flushed and changed over to Final Charge (Or whatever you choose.) at the same time. So you can carry a spare gallon of say 50/50 Final Charge to cover for top off's of both.

Palehorse89's process of flushing with distilled water is the route we went too, and yes to the blank cartridge.

Good time to check hoses too, and a new thermostat sure would not hurt either

!

Best of luck to you, and again, welcome,

Yes, belts, hoses and thermostat while in there, per posts on this forum. I will be following instructions of "Freedmeister" from 11/2013; he gives a great tutorial! I really appreciate all the help and support from the folks here! THX TB

Hi TanDD. I cam across your posts about changing a radiator in the holiday rambler. I have that leaky radiator in mine too. Having trouble finding a replacement radiator. Can you give me some leads? Not sure what you did with the coolant you where using did you have any recommendations?

OP...our 2000 8.3 ISC 330 required Compleat EG (blue) coolant, according to Cummins. Something about coolant sensor compatibility. Anyways, a new water pump, hoses, flush and fill with six gallons of Compleat EG Blue concentrate and it hasn't been an issue. The coolant will probably outlive me lol....
You may want to check with Dr. Cummins if OAT, such as Final Charge is right for you.
