12 does it for mine

I put in 12 quarts routinely. Actually, I save out about 1/2 quart, run it for about 3 or 4 minutes, then let it sit for 3 or 4, check the level, and usually find adding the remainder of 12 is necessary to bring it right to the full mark.



I had a bit of a leak of anti-freeze (from the block heater being loose) and bought a gallon of HOAT antifreeze at a dealer. It was $13, so I hope it is available elsewhere. I also bought a gallon of distilled water at the grocery store, and added 50/50 until the reservoir was midway between the MIN and MAX marks when cold.

If you look at Fleetgard, you can get the pre-mix Extreme 650,000 mile stuff for around $8. 00 a gallon and save yourself trying, to be you own best chemist.

Actually, it's HOAT, which stands for Hybrid Organic Additive Technology. It's now used on pretty much every vehicle sold in the US... it's just colored differently. Dodge and Ford use an orange color, GM uses a yellow color. All the same stuff. You can now buy the stuff at any auto parts store, usually under the name "Zerex". It's also supposed to be fully compatible with ethylene glycol and propylene glycol (since it's really glycol based).



I made the mistake of thinking the HOAT would be a lot like DexCool was several years back: everyone thought it was the greatest stuff ever until it started clogging heater cores and radiators and generally making a terrible mess of things. So I paid Cummins a small fortune to change over to Fleetguard Propylene Glycol. In hindsight, totally unnecessary. Oh well, live and learn.

Compatibility

Before you mix HOAT with ethylene glycol type, check at least your owner's manual, if not the manufacturer or perhaps your dealer. I don't have my manual handy, but recall that when I read it, and when I picked up my truck new, DON'T mix with ethylene glycol type was emphasized. When mixed, the allegation was that it became a clogging gel. Haven't done it, so I cannot say for sure, but if you are tempted, check it out first.

As far as the oil goes it's 12 quarts if you change the filter, 11 if you do not. It's in the manual, it also reconmends you prefill the new filter with clean oil before you put it on.

Antifreeze/Coolant

Getting ready to change out antifreeze/coolant in the wife's Jimmy,went by Walmart yesterday to pickup some Havoline coolant as the equvilant in what the owners manual stated. Right next to it was 5/150 Prestone stamped GM approved Dex-Cool on front of jug, same marking as on the Havoline. I was reading this Prestone in a silver jug,organge cap is also compatiable for Daimler Chrysler use in 2001 an newer vehicles. Also stating Hybrid formulations including Zerex G-05, Mopar HOAT,an Motorcraft Preminum Gold antifreeze/coolant. So would'nt you think the Cummins engine would be included since we use a Hoat antifreeze/coolant an said Mopar HOAT as a listing.

I can attest to this. This took place in my old Zepher wagon. And guys, once it gels, you ain't getting it out. You have to replace the radiator and the heater core.



Best thing if you are going to change out to a different fluid is to do a complete system flush with 3 caps of Electrosol powder dishwashing soap in to a radiator that has just clean water in it. Drive it till you are at operating temp. Then rinse out 3 to 4 time and install you new fluid. Electrosol works very nice, is very cheap 25 cents for 3 caps of it and it does superb job of getting rid of rust if you have any starting. Learned that from an old Diesel mech.

Before I changed mine out, I asked Fleetguard whether there was any danger mixing their EG or PG formulations with other types of antifreeze. Here's their response, cut-and-pasted:



Thank you for contacting Fleetguard.



When using our ES Compleat, we know of no chemical issues when mixing with other manufactures antifreeze. Since you Dodge does not have a water filter, ES liquid should be added on a annual basis in order to keep your antifreeze in proper working conditions. If you maintain you cooling system with our ES Compleat and add the recommended amount or our ES extender, this antifreeze can be used until the first engine rebuild unless, for some reason, the cooling system gets contaminated with fuel or oil.



If we can be of further assistance to you, please feel free to contact your Fleetguard Customer Assistance Center @ 800-223-4583.

I've had ES Compleat PG concentrate at a 50/50 ratio for about 6 months now... no problems to note.
