Has anyone used the Sinister Diesel kit for your truck? Care to comment on installation and use?

Why do you need a coolant filtration system on the 6.7? The 6.7 uses the same coolant that gasoline engines in your explorer, escapee, chevy, dodge etc uses. The coolant is the DEXcool or equivalent. You do not see filtration systems on gasoline engines do you?

This for sure would be a waste of money in my mind.

Hi Larry; I guess that I read too much some times. I get Diesel Tech magazine, plus a few other subscriptions, and I was reading about coolant filtration today. According to what I read, the 7.3 and 6.0 definitely need filtration, but the 6.7, not so much; but should still be filtered. All of the major suppliers make a coolant filtration kit for the 6.7 for a nominal fee, and basically easy install, so yes, I was considering. That's why I posted here; for input. Let's see; that's 1 'no'.

Ford also says in the maintenance schedule to change the coolant in both systems at 105,000 miles. Not sure the requirement of the 7.3, 6.0 or 6.4. I could see a filtration setup if you were going to run the coolant 250,000, 500,000 or more miles like the big rigs.

OMG people - get in your truck and drive it. All this extra filter, separators, CJ vs CK oils, truck stop fuel vs normal sized station fuels, cold air intakes, SeaFoam, DEF deletes, DPF deletes, and other additive crap discussions are senseless. There are hundreds of thousands of trucks on the road and the owners don't worry themselves silly on forums - probably don't even know forums exist. Their trucks run just fine forever by putting in diesel fuel from the nearest station and changing the oil once in a while.

FLAME ON!!!

Good grief, where do you people come from? If you're not interested in sharing ideas and discussing possible modifications, what are you doing here? I could find a lot better things to do than hang out a web site like a child molester at a kiddie bathroom.

I did offer an idea......the filtration is money in the seller's pocket and less money in your pocket....my idea is to use the cost of the filtration unit to pay for changing the coolant at 105,000 miles......and use some of the money to buy one of the vacuum fill kits to avoid air pockets.

Yes, Larry; you usually give me good advice/suggestions.

Please explain why you are on this "silly forum" if this is the case

Since the '11 release of the 6.7L it has not been known or repeatably discussed to need a coolant filtration kit. For the cost of the coolant filter kit compared to flushing, how much coolant could you buy?

I see that DexCool approved coolants also have the Ford spec listed but I have personally delat with several dexcool GM vehicles with the Dexcool sludge disorder.
I'd love for a chemical engineer with automotive coolant experience to explain this. I LOVE Shell ELC as it fixes 6.0 oil cooler plugging. 6.0 oil coolers I have replaced and used ELC red coolant in have gone twice the oil cooler plug milage with no coolant change and no issues and ECT-EOT spread staying at 8-10 degrees. I had to replace the radiator on one the other day as I saw the seam had a small leak that I know would turn into a tank blowout. That red coolant had been in there since 2009 and the truck had gone 127K miles. There was nothing in the rad and I pulled block plugs and nothing there either. The only thing I see is the rad was white inside tanks as I pulled tanks off so the rad would bring more $ in my scrap run. That white crust is there to some degree on any I ever pull tanks on for that reason so I would not judge that one to be any worse than any gaoline engine pickup rad I have changed with 200K miles and 10+ years of use.

I'm not promoting that the coolant stays in that long but this truck had not had it flushed as I recommended since I did the cooler on it.


Oh BTW, there are certainly mods that no question have positive effects. But many of us here would take the care needed to assure no issues that make some of these mods unnecessary. I see a coolant filter system as catching silicate drop-out as good coolant maintenance keeps anything else out of system. Use f coolants that do not pose that risk would make a coolant filter unneeded. Class 8 trucks don't have coolant filters since long-life diesel coolants with silicate and cavitation issues addressed started being the fill for cooling systems on those. The filters were the best way for those trucks to have a slow dissolve disc of the cavitation suppressing additive in the system.

Well, when i read ideas, a lot of times I post here for suggestions. I always get good replies and I appreciate that. So, based on those replies, I don't need a coolant filter.

Clev....not mentioned....the 6.7 has TWO SEPARATE cooling systems.....did any of the filtration setups filter both cooling systems?

Yes, it did refer to two systems, and the coolant filtration was for the 'engine side', I think. I would have to find and re-read the article to be sure.

ok...ok and holy moly!!! The entire coolant filtration panic epidemic started when casting sand was found to cause damage on the coolant side of certain engines; including gasoline engines where the manufacturing process left casting sand in the finished product.

The enterprise of selling filtration systems to remove residual sand from any engine that the owner could be convinced had this problem became a lucrative business. There is no reason for the purveyors of these devices to help us understand which specific engines were manufactured in such a way that they do not need coolant filtration.

You can do some 'inter-web' research for yourself, but i think that the engines most recognized for this affliction were the 2012 to 2017 Jeep Wrangler/Chrysler V6.

If you have 'improved' your Power Stroke by deleting, 'tuning', bypassing, 'improving' Ford engineering, you are shi*&%ng in church if you think coolant filtration is your problem. I assure you that lack of coolant filtration is not what will destroy your $13k engine.

No one mentioned anything about having a problem with the engine. No one brought up deleting or modifying. Except for a couple of posts, it's been a good discussion on either 'needing' or 'not needing' additional coolant filtration.

Thanks clev, and i hope that i have contributed to the discussion of 'needing or not needing' coolant filtration. The discussion relates to fears of problems with the engine if coolant filtration is not installed. Maybe some 7.3s had residual casting sand problems and maybe some 6.0s did, i think that the 6.4s and beyond are free of this problem.

NO you do not need coolant filtration on a 2012 truck.

Yes, somebody did bring up deleting or modifying, I DID! To surmise: Adding coolant filtration is not necessary, but is a no-harm modification.

And this entire discussion is based on wether or not you will have a problem with your engine if you do not install the Sinister Diesel Coolant Filtration Kit on you truck.

If one was going to operate their truck commercial and put a million miles on it, then it might be beneficial. Ford maintenance says to change cool at 60,000 when operating under harsh conditions such as towing heavy,, extended idling and other parameters. The normal change is 105,000 miles. Many owners will never reach the 105,000 miles before they trade or sell their truck.

Also, on a complete flush/fill, you do drain the block to the extent possible with the plugs you remove from the block during the process.

The stuff that was being called casting sand is silicate bits from silicate containing coolant degrading where the silicate precipitates and forms crystallized bits. 6.7 coolant is not a silicate component coolant. I see no trucks in my shop with coolant filters but I did see many with silicate bits. I never see impeller damage on water pumps I remove from those trucks with noticeable silicate bits. I have been flushing and replacing coolant with non silicate CAT ELC for 10+ years. Trucks with that coolant do not develop silicate dropout. 6.0 engine trucks with this done at oil cooler change have not had another oil cooler change needed due to EOT to ECT temp difference from silicate bits clogging oil cooler. In the 7 years 6.7 engines have been out I see no activity on oil coolers getting clogged so the non-silicate coolant used seems to not be causing issues. Radiators leaking- yes, some water pumps leaking- yes. Those failures do not seem to be coolant related and water pump failures have not been widespread even on 200K mile trucks without coolant ever changed.
