Flushing system soon...couple of questions

[Adamv7010]

My deltas at 60-70 MPH are between 9-11...I'm within acceptable ...but wish they were lower...

Whole still on stock bolts at 102k miles I'm cautious ...

I'm going to flush...but my question ...should I install a coolant filter for a while before I flush and swap to an elc?

I don't want to risk pushing something into the oc but realize this is an all but unavoidable risk...

Second question ...I read about guys doing a water only flush, without vc9 or restore..

Using water vs an acidic cleaner, what are the pros or cons?

Thanks in advanced

This weekend I'm going to install some fumoto drain valves in the block hopefully. Then I plan to run the engine with water flowing into the degas bottle with everything opened up. I plan to run it like that, inreasing rpm's, idling, etc to try to push as much sand out of the system as I can. Then I will back flush the oil cooler (probably wont do much good, but its not like it will hurt. Then button everything up and run some cleaner through it. Drain it, open all the valves and do exactly the same as the first step. Then back flush the oil cooler. Then start the process of adding distilled water a few times, then fill it up with coolant.

My suggestion is to put a coolant filter on your truck, and monitor your temps. If you want to change over to elc, drain flush with tap till clear, flush with 24 gal of distilled, drain and add elc. I was personally going to do the restore and restore plus, but almost everyone clogs their cooler. Yours is ok, why clog it? Maybe someone on the org can tell us how a dump, water flush, and refill with elc, can be harmful when deltas are sill ok.

I've been looking @ filters....I've read mixed reviews about the sinister kits lately..

What's everyone using now?

I ordered xdp, because it was on sale. Lots of guys are using sinister.

I am running performance machine coolant filter. It was easy to install and the billet filter base looks good too. As for the cleaners, I didnt have bad deltas but was going to do studs (and update everything) so i took the time to flush with the cleaners. I ran tap water with everything open as mentioned above in the previous post and did the fillling and flusing with tap water several times too. After all of that, i ran each cleaner with several flushes between both cleaners and couldnt believe the crap that came out of the system. I forget which cleaner removes the silicates and which does the iron deposits, but the silicate cleaner caused the fluid i drained go from being what looked like tap water that was safe to drink coming out of the block to a milky sludge that looked more like itallian salad dressing. sounds weird but cant think of anything else that it looked like. Did the same thing with teh second cleaner. water came out almost black, again that was after multiple flushes with tap water. After all of that and installing the coolant filter and ELC coolant, dealts on my oil cooler i replaced anyway (cause it was only $250) are within a couple degrees under most conditions unless towing 10k trailer up a grade when its 115 here in AZ. Just my experience...

How is it possible that a super expensive truck such as these suffer from cooling system "sludge" or debris that bad? How is it that to just change coolants you have to go through a days worth of complicated and time consuming, expensive flushing...install filters...and end up with a clogged oil cooler?

What about these trucks makes the cooling system the worst cooling system ever created? I've seen people take engines (gas and diesel alike) and just drain and refill...eventually putting 500K on them without the first hint of a problem. Yet these trucks seem to cause so much trouble. Were the blocks intentionally filled with dirt? Does the metal dissolve from the Ford Gold coolant?

I've drained and refiled my Ford Gold coolant and it looks pretty good. From what I can see inside the hoses, tanks and such...everything looks pretty good. So I just refilled with the same. I'd like to just drain, flush with distilled water, and refill with ELC and forget. But who knows what kind of "damage" that could cause on a system that seems to be trashed on day one from the factory.

I'd really like to know what VC9 etc does to the radiator and heater core.

It is a well documented chain reaction of events, just not well received.

Adam your delta's are good. Why not wait since you have a way to monitor them. You will have to change the cooler once you proceed with the flush

Agreed. Personally, I'd test the coolant to check its condition, dump it if its bad and replace with Ford Gold, buy a monitoring solution and a coolant filter, and drive. Flushing now may clog the cooler. Wait until its actually clogged, flush, replace the cooler, and fill with ELC.
