Yep, If you look through the link Farm posted they state that you should not use some anti freez in pre 99's. Thanks Farm

 

This is where I get them FLEETGUARD - COOLANT TEST STRIPS (4 PACK)-Dodge Cummins Diesel Truck Accessories – Geno’s Garage

They have the additive too.

 

Found a thread a while back with the spec. The key seems to be a low silicate coolant.

 

So are ELC coolants not recommended in our rigs?

 

Thanks a lot Scatgo, I appreciate that!

That seems to be the case. Somthing about OAT's in the ELC. Organic Acid Technology. Bad for injector cups and other seals and stuff.

See post #3 in the link you gave..

 

Looks like I lucked out... I'm using Fleetcharge which is not a ELC.

I can't believe I didn't know about the OAT before. I know I looked into coolants when I did my flush a couple months back.

 

The late 466 had the SS sleeves (cups).
I have never seen a 7.3 (444) with SS sleeves (cups).
I would like to see a part#.

Sorry all. I thought I had read that there was a difference in the sleeve construction / material. Evidently not.

Thanks to Bill for correcting my brain f**t!

 

Well something has to be different that allowes the use of the ELC.

This is from the link that was posted..................



International's recommendation is based on extensive testing that showed compatibility issues with OAT-containing coolants and INJECTOR CUP MATERIAL, sensors, o-rings, gaskets, front cover, and probably some other things. However, engines made after 2/2/99 (SN 940614) were revised to be completely compatible with OAT-containing coolant.

Note HOAT and OAT

Cooling system maintenance
The cooling system on any diesel has special concerns. It's possible for the coolant to cavitate--produce tiny bubbles--that can with time cause pin holes throught the cylinder walls from the water jackets. For this there is an additive; Ford P/N FW-15 or FW-16, Fleetguard P/N DCA4; that needs to be maintained in the coolant. Generally this means installing 8 to 10 oz of the additive to the cooling system every 15000 miles. Another method is to monitor the cooling system with Fleetguard's DCA4 test kit P/N CC2602 or CC2602A. This measures the level of DCA4 in the system, then you add the amount of SCA/DCA as required to reach a nitrite level of 1.2-3.0 PPM. The cooling system should be drained (and flushed if you live in an area with especialy alkiline water) and refilled with a fresh 50/50 mix of coolant/distilled or demineralized water and one pint of the additive for every two gallons of coolant/water at 30,000 miles. Use only a ethylene glycol-based coolant, preferably low-silicate.
Antifreezes I can recommend:

Ford or Motorcraft Premium Antifreeze
Texaco Antifreeze/Coolant
Texaco Antifreeze/Coolant Prediluted 50/50
Zerex 5/100 (white bottle) Antifreeze/Coolant
Zerex Ready To Use Antifreeze/Coolant (premixed 50/50 with demineralized water)
Zerex Heavy Duty Precharged Formula
Shellzone Premium Quality Antifreeze
Prestone Heavy Duty (black bottle) Antifreeze/Coolant with SCA
Fleetguard Compleat EG--precharged at 1.5 units/gallon DCA4
Also available premixed 50/50 with water with the same DCA4 level
Pyroil Heavy-Duty Antifreeze/Coolant--Low Silicate
Peak Full Force or Advance
FleetCharge Antifreeze/Coolant--precharged with Pencool
WalMart Super Tech
2002 model year trucks use any of the above if your truck came filled with green coolant. If it came from the factory with yellow coolant, only use Motorcraft Premium Gold Long Life Antifreeze, Zerex G05 (gold bottle), Peak Global Lifetime (gold bottle) or Peak Extended Life CF-EXL (silver bottle). These coolants are fully-formulated using hybrid organic acid technology (HOAT) and do not require SCA/DCA. Recommended service interval with the gold coolant is 5 years or 100,000 miles. Test the gold coolant periodically for pH balance and freeze protection.

Trucks originally filled with Gold coolant:
All 2002 F-Series built at the Kentucky Truck Plant (VIN 11th digit "E")
2002 F150-550 built in Cuautitlan (VIN "M") from 2-4-02
2002 F650/750 built in Cuautitlan from 1-28-02
All Econolines built from 7-15-02
Ford has approved using the gold HOAT coolants in their vehicles as far back as the 1999 model year, providing the cooling system has been thoroughly flushed to remove all traces of the green coolant. If regular tap water is used instead of distilled or demineralized water, the recommended service interval is only 50,000 miles.
Ford does not recommend using propylene glycol-based coolants in any of their vehicles, or "universal" coolants that claim to be a replacement for any color antifreeze. They also have not approved the use of any organic acid tecnology (OAT) extended life coolants (ELC) in the PowerStroke cooling system.

Thanks for clearing that up Bill. I was running around with my head cut off lastnight until I finally found a bottle of the stuff that I'm using in my stroker. Luckily I have one that is approved.

Reps sent to ya!
