    Casting Sand: 6.4 Hemi HD Coolant Filter

    I took my v labs filter off. It’s an every couple of days cleaning if I want to keep using it. What we need is one of these maybe. I haven’t found one online that is rated for 220+ degrees. Having a bowl to spin off and rinse would be much more manageable and would take longer to plug up.

    Casting Sand: 6.4 Hemi HD Coolant Filter

    I thought about this and have been researching it but I’m not sure where to put it (the filter base and filter) since nobody has done it on a 6.4 Hemi. I’ve reached out on this forum and one on Facebook but haven’t gotten any info.

    Casting Sand: 6.4 Hemi HD Coolant Filter

    I’m of the conclusion now after lots of reading and re-examining the material that came out that I have had tap water used on one of my refills even though I was assured they used the provided distilled water. I appreciate everyone contributing thoughts and ideas on this issue throughout the...

    Casting Sand: 6.4 Hemi HD Coolant Filter

    The zoom of the picture makes them seem pretty large but the biggest ones are probably 1/8”. I put some vinegar in and it didn’t seem to do anything to them, they don’t melt and a magnet has no attraction so they don’t seem to be calcium, plastic or anything with metal in them. They are brown...

    Casting Sand: 6.4 Hemi HD Coolant Filter

    I was getting too many mystery flakes with mine so I took it off a couple hours ago. It definitely works but my system is way too contaminated for it. I’m wondering now if maybe it’s cooked coolant from the egr cooler that is breaking free from the walls. It’s like a bunch of well defined...

    Casting Sand: 6.4 Hemi HD Coolant Filter

    This makes sense. Maybe certain days during production there was more sand in the coolant than other days that’s why it’s not a 100% problem.

    Casting Sand: 6.4 Hemi HD Coolant Filter

    This is what came out of mine and there was no evidence of anything else in it. Vent temp went from lukewarm to 170* after I back flushed it and I’ve had the same results each time. I’ve back flushed it 6 times in 2 years. The problem started after I changed my thermostat, then a couple weeks...

    Here’s a couple other screenshots involving other claims for the same general problem:

    Casting Sand: 6.4 Hemi HD Coolant Filter

    That makes me wonder if there is a chemical reaction happening between the new OAT coolant and some cooling system parts that is producing something that resembles sand. There is another class action lawsuit I found that is filled against FCA alleging something like that.

    Casting Sand: 6.4 Hemi HD Coolant Filter

    Not sure why your system sent you to a cyberattack screen when mine never does. So I’ll post a couple of screenshots for you so you can see that it is indeed a class action lawsuit filed in New York against FCA. I shared it for those who think only tinfoil hat wearing Ram owner’s think there’s a...

    Casting Sand: 6.4 Hemi HD Coolant Filter

    There are a number of Jeep owners who have plumbed these filters in-line to the heater supposedly. Seems like my continually clogged heater core is a pretty huge heating issue right now. If I could find a bowl type strainer that are rated for high heat that would be ideal.

    Casting Sand: 6.4 Hemi HD Coolant Filter

    Maybe each version has its own casting sand purge station/system/department and the 6.4 HD has some kinks.?

    Casting Sand: 6.4 Hemi HD Coolant Filter

    This is one of the things that I can’t figure out, when people say they’ve never heard of anything like this. This forum alone is overpopulated with posts about 6.4 HD clogged heater cores, and a Ram HD Gasser page on Facebook is getting posts about this issue almost weekly, though once it...

    Coolant problem

    It looks that way but it turns fine when you rub it down like the stuff stuck to the middle of the bag in the picture. All of these are flakes too (thin and wide) like a light glaze that broke loose, it reminds me of sand dust that finally got rinsed off a surface. It doesn’t melt (I tried since...

    Coolant problem

    Is it possible that the purge procedure is faulty and they think it’s more money to retool than it’s worth? Here’s a picture of some of the stuff I flushed once it’s dry.

    Coolant problem

    I just talked to them. Blackstone doesn’t do anything like testing just the particles I flushed out. Could send them some coolant but it’s pretty fresh 150k mile Mopar oat so I’d hate to blow $40 on sending in my coolant just for them to tell me it still has plenty of miles left in it. I could...

    Coolant problem

    Our calcium in this part of Texas is white and that’s where this truck has spent it’s life, plus it’s never had tap water in it. Those little chunks rub down to something like dust. I wish I knew where to get it analyzed. My theory right now is that it’s the dust of the casting sand that was...

    Coolant problem

    I’ve had it installed for just over a week. It’s not a large quantity of sand after 4 hours but it’s enough to degrade the flow enough that the oil cooler and heater core would quit being able to do their job. I think a spin on coolant filter is the only solution if I don’t want to either keep...

    Coolant problem

    2014 2500 6.4. There is definitely a sand-like substance in these blocks. This is the only foreign material that I’ve flushed from my heater core and done it like 6 times in the last 2 years, (that’s when I put in a new thermostat then new Mopar oat/ distilled water, then drained again and it...
