Coolant - this may surprise a few folks ...

Well, I must admit ........

I have put up a few posts in the past stating my opinion on the Ford Gold coolant (ie that it isn't the "ROOT" cause issue of all of the 6.0L problems).

My 105k miles on the Ford Gold has been trouble free (and I have no clogging of the oil cooler).

I have stated before that I know a dozen or more folks w/ 150k to 200k + miles and no issues with gelled coolant plugging the oil cooler. One person I know is around 200k miles, tuned (500 RWHP IIRC), running w/ the original OEM EGR and oil coolers AND running the Ford Gold. ALSO - he has no coolant filter. Never has had one.

I am not so brave, so I added a coolant filter early on and filtered out a TON of casting sand (thank goodness I installed the filter)! Not too much later on, I installed a BulletPRoofDiesel EGR cooler - just to be safe. I did not change out the original oil cooler though.

I also decided at 50k miles that I would flush the coolant (no chemicals- just a LOT of distilled water) and go back in with the Ford Gold.

Recently (95k miles) I installed head studs (no gasket leaks, this was a preventative measure) and have periodically run a canned SCT tune. A friend got me a new oil cooler real cheap, so when the studs were done, I took out the original oil cooler - no plugging. After installing all the upgrades, the ECT/EOT deltas were identical to before - further proof that I had no plugging w/ all the miles on the Ford Gold.

Now - two weeks ago I bought 5 gallons of Rotella Ultra ELC coolant. This weekend I will be flushing out the Gold and charging the system w/ the ELC coolant (I guess I just am stuck on the gold/yellow color - lol). I imagine this will be surprising to some (since I have been accused of being a "blind Ford fan" - LOL).

I have not changed my mind on the Gold though!

I firmly believe that there MUST be something (some failure) that initiates the Ford Gold to gell. I know that it is not entirely silicates, because there is only 1/2 ounce of silicates in a full charge of coolant. Ford has said that combustion gasses will cause the Gold to gell. I personally believe (as many do) that excessive temperatures can also cause the gelling, but a well running engine will not expose the coolant to an excessive temperature. I monitor the coolant temps, the EGR valve operation, the coolant degas pressure, etc, and I just don't see how a problem could develop ....
UNLESS ............. you experience EGT's skyrocketing from stuck turbo vanes, leaking head gaskets develop, a low coolant level is allowed to happen, a water pump fails, even the block heaters have been implicated, etc. I also believe that the issue could be triggered with using tap water and possibly with mixing coolants.

All that being said, I believe that the Ford Gold is MORE susceptible to gelling than the ELC coolant (and I have personally seen one case of the ELC gelling and heard of another). It would be hard to ignore the data that supports this concept!

Since no one can predict when an issue could happen to cause excessive temps, or failed head gaskets, or whatever, etc. - I do think that it will add some reliability by switching.

I have in NO way been worried about coolant gelling, but the coolant switch has been on a LONG list of things to get to - eventually.

Well, the time is now here and I will be "conforming" this weekend. I probably still won't change my opinions on the Gold, but the ELC Ultra is "supposed to be" some pretty good stuff!!

I have block drains and a thermostat housing with no thermostat, so my flushes should go easily and quickly. I figure that 4 flushes will be sufficient, but have enough water for 5.

Thought I would just put up a post on it before "sneaking" it into my signature - LOL!

I wouldn't expect anything different from you.

Thanks for posting your switch.

I'm only at 51,000 on the truck, and I'm on my third charge.

Thanks for posting your switch, i would get some ph test strips and flush until you get to a 7.0 ph good choice of a coolant.

Thanks for the suggestion 2 stroker. I will be measuring how much I get out from the radiator drain and then how much more I get from the block drains. I have always been curious about that. From that information, I will know how many flushes will be required for a 99% changeout. I will also see what the pH strips tell me.

I must admit im one of the 200k+ miles 6.0s that still has stock headbolts, egr, oil cooler, and ford gold coolant

Freakin' show off!!!

Really though, I'm hoping I got my 04 early enough to beat the odds on all the issues these had.

Good job.

THANKS for the post! Sometimes, when it comes to the forums, I feel that I am alone in that camp! Blaming the coolant alone just doesn't account for folks like you! As I have said a few times (I know - it is harping) - you just don't see "reliability by chance" in mechanical equipment .............. the principles of chemistry, heat transfer, etc are the same for us all!!!

That being said, next week I may be encouraging you to switch though ...... LOL!

I may need to ask you to lose my e-mail address! My coolant isn't red!
