What brand of coolant are you running? I'm building a diy coolant bypass filter. I'm going to be using Fleet Charge coolant, it's the only thing I can get locally without buying it a case at time and paying the shipping to the store and hazmat.

 

FLYWHEEL. On the ECSB the a$$ end is all over the place even on Level 2which I run daily. Level 2 =450 HP Flywheel

 

on the original post the thread that was linked to was talking about material incompatibility with the cups and seals in the older engines. however since i'm dumping in a full reman long block with new cups and a new gasket set, do ya think the materials are updated. I'm betting thy would be. would appreciate some opinions.

I would also bet your reman has updated materials but if possible I would contact the company that remanned the block and ask them.

 

I'm probably due for a coolant change and now I'm all paranoid I can't put ELC in it. WTF.

 

I haven't ever been able to get a clear cut answer on this. Here is a chart that I got from Guzzle. FWIW I run the ELC in my Early 99, but only for about a year so far.

 

What is "GY"? I had a 2000 Ranger and it ran standard green AFAIK. I changed it out at about 3 years with standard Prestone green after it started turning colors....

 

this is a complete pain in the ***.

 

Sorry, this will help.

 

Yeah, I'm sure. What year was your engine built?

 

unsure, but she's def an e99 truck. i can look when i get home.

 

Okay -- early 99s most likely can't run ELC per Ford, but a lot of folks have done it anyway. If you're that worried about it, take back the ELC and get the plain ol' green stuff. But be warned if you try the ELC, you might have to do injector cups. Not a very pleasant job, honestly.

 

Wayne, Mark(Maevans) did a lot of leg work on this subject and decided to stick with conventional coolant with SCA. After talking with him and several others I choose to continue to use conventional also. IIRC. Robin had to replace his injector cups earlier this year. It's really a crap shoot with our early 99s.

 

I guess I'm sticking with **** coolant and SCA damnit! lol

 

It's just my opinion, but since Ford didn't make the engines, I go by what International recommends, since they made the engines for Ford.

International recommends an Organic Acid Technology (OAT) Heavy Duty Extended Life Coolant (ELC) for the L99 and up 7.3's, but Ford doesn't.

Ford recommends their "gold" (Zerex G-05 equivalent) Hybrid-Organic Acid Technology (H-OAT) coolant starting with the '02 model year 7.3's.

After much research, International discovered an OAT based coolant doesn't work well and has compatibility issues with the older injector cup material, sensors, front cover, seals, gaskets, o-rings, and other stuff, like certain head gaskets that have silicone sealing rings for the coolant flow holes. To be certain, the problems found with the older type of sealant used during injector cup installation, which doesn't mix well with an OAT ELC, is enough to stop someone in their tracks.

Coolants like ELC's (usually Red) and G-05 (usually Gold) will have these OAT's. Conventional coolants (usually Green) will not.

So, with these incompatibility issues, International revised the necessary components on all 2/2/99-up build engines (SN 940614-up), and began recommending and factory filling with HD ELC coolants mid-year 2000.

GM's Dexcool is an Organic Acid Technology (OAT) coolant, but not all OAT coolants are like what GM uses.

GM typically uses a forumulation which is specifically not recommended for your diesel engine. Dexcool type coolants were absolutely never intended to be used for diesel applications.

There are many modern Heavy Duty Extended Life Coolants specifically designed for diesels. Delo ELC, Rotella ELC, International's Fleetrite ELC, CAT ELC, Mobil 1 ELC, and a host of others.

Compared to conventional "green" coolants, ELC's will address diesel cavitatation protection and provide superior metal corrosion protection, provide better heat transfer, require no testing and maintenance, be free of harmful abrasive silicates, borates, and phosphates, and have an operating life up to 1 million miles (Delo ELC).

Ford's "Gold" (G-05) coolant is nothing like a Heavy Duty ELC coolant, and it will not meet the strict specs required of a HD ELC coolant, or provide the higher level of protection.

The "Gold" is simply a universal hybrid, one-size-fits-all coolant that Ford uses in its entire line up that, with the exception of the Powerstroke, are all gasoline engines. Ford simply uses the "Gold" in the 7.3L PSD out of convenience, simplicity, cost, and uniformity throughout it's product line and dealerships.

The "Gold" coolant contains conventional "green" coolant components, like silicates, which eventually form microscopic abrasives that eat water pump seals. The "Gold" provides a lower level of cavitation protection using traditional SCA's like nitrite, it has a shorter life, it's not as effective as an ELC at heat transfer, and in some applications, requires testing and SCA maintenance (just like the conventional "green" coolant) if you are an enthusiast about protecting your engine.

In fact, Ford recommends you add SCA's to the "Gold" in certain F-Series applications. Caterpillar and John Deere also recommend adding SCA if it is going to be used in their diesels.

Ford's H-OAT "Gold" coolant will not meet International's heavy duty diesel B-1 specification. A Heavy Duty ELC will.

The "Gold" will work, but it's not the best.
