Casting Sand: 6.4 Hemi HD Coolant Filter

Mister Luck · Mar 6, 2022

A coolant filter could be similarly placed mounted near the right frame rail inside the engine bay or similarly like an oil
catch can with the filter boss feeding the heater core intake hose. It would be advisable to remove if your 2014 has thermostatic coolant temp valve and run those lines to heater core hoses… but a coolant bypass to relive the flow of a open loop / closed thermostat would probably involve tapping a radiator hose adapter (sleeve)

I've considered getting one of these inline filter. My heater core was clogged beginning of winter. I back flushed it and began getting heat but I still think it's clogged a good bit.

This is interesting, I was warned by a buddy of mine, he had the "sand" in his 3.6 Jeep Wrangler's oil. When I first got my Power Wagon (2018) I changed the oil after 1500 miles, found similar particles in my oil filter when I opened the oil filter, so needless to say the first three oil changes were at 1500 mile intervals. At the 4500 mile mark I sent off a sample to Blackstone. They told me I was changing my oil to early LOL! I guess I will need to flush the coolant system soon. (I have 30K on the clock)

After reading about the coolant problems I contacted a diesel expert I know and asked him about the coolant filter. His reply that the diesel coolant filters addresses a different problem, and most likely would not help in gas systems.

I also asked him about the screen filter someone posted and he basically said it was a waste of money. I will be following this, since I would be interested of getting a coolant filter too. Figure it will need to filter at a low pressure while not decreasing flow volume, or creating undue pressure in the system.

The casting sand is real, not common but I’ve seen this before including just recently.
Changed my Thermostat, 2017 6.4, in January and could fell the casting sand in the antifreeze. I didn’t have time to flush the system but plan to this summer.

I've had my Ram in multiple times for casting block sand. That is what they keep telling me that's what's causing my problem. On my 3rd heater core. Couple of radiator flushes. 3100 bucks into it. They have had a lawsuit with one of the other vehicles already. And they were told to replace the radiator and the heater core and a engine flush on that particular vehicle. This sand / mud combo does not go away. 130000 miles on my 2014 ram 2500 and it keeps showing up more and more. Didn't have a problem when it was new. Now Ive noticed that going down the road the water pump, pumps adequate water until you come to a stop and the water flow slows way down and the vents go cold. More so on the drivers side than passenger side. They said the heater cores are two different halfs put together? Replaced all motors and blend doors and tested them. Here is the pic from today 3/11/22 that came out of an inline VeLab filter. That they installed before my heater core. It plugged up tight so no flow would run thru the core. It heats fare once you clean it, but its a pain in the ass cleaning all the time. Thats not the permanent fix. They have a problem with crap in there engines. VeLab makes radiator filters to stop any junk from going into it. This is my 3rd ram and I am done buying junk.

Erikk · Mar 12, 2022

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.

I was looking at this, made for the Jeep JK models, I need to call Mishimoto to see if I could adapt it to the 6.4. Just need to know if it matters which direction the coolant flows

Al Handy · Dec 9, 2022

Up Date: I called Mishimoto and discussed the installation of their kit on our Hemi's. They indicated that they have not performed installation on a Hemi, but could not see why it would not work. I have the kit now, problem is......I can't seem to find a flow diagram that tells you which way the heater core is supplied. I am being lazy, I could go out start the truck and hold each of the hoses as the truck warms. IMHO direction of the flow is important on this kit since the coolant must flow correctly in the filter.

Why not buy a cheap engine oil filter relocation kit,and use a coolant filter on it.

I had this same issue with my 2016 Ram 2500 last Winter. My heater core was plugged solid. I backflushed it and all this gritty brown crap came out of the heater core. I bought a cheap inline clear screw off filter from Amazon for around $15.00 and two brass fittings for around $12.00. I cut the intake hose on the heater and installed this inline. Just today I had to clean the screen out again. It was plugged with the fine gritty brown ****. I washed out the screen and my heat is back to normal again. I posted this info up on the FB 4th Gen Ram page with part numbers and pictures.

.here is the filter that I used. The nipples are straight brass 5/8 male with 3/4 npt male end. I'll post a picture of my installed filter tomorrow.

jimrobert · Dec 18, 2022

Here is the filter installed. The top hose on my 2500 is the heater core intake. You may notice that the hose is against the firewall now. Normally it is the outward hose on the firewall clamp. Had I not moved it, the filter would be almost sideways . I didnt want that to be sideways. I switched the hose positions in that clamp. I can easy unscrew the filter to wash it out. I also clamp off the hoses before taking the filter off .

Hello everyone, I am glad I found this article as I have been dealing with this same issue for about a year. Started with just flushing the system every couple weeks to get heat, and now in the last three months have been running an inline filter on the heater core lines. I am taking the filter off every 3-4 days to clean it as it clogs that fast. Has anyone contacted Chrysler and had any luck to a solution? I have mechanic friend that has been working on this with me since it started, and he suspects it could potentially be the EGR cooler breaking down... I will try to add pictures, but I'm new to the forum so not sure it will work. These pictures are from the filter after about 4 days of driving/running. I don't drive a lot either. One picture is of it wet, the other is when it has dried.

I spoke with a local radiator shop today. Finally got sick of dealing with this. His first question when I told him what was going on, "is it a Dodge?" He stated that he has seen more issues with the ram pickups having casting block sand in the system that the cars and suvs with the penstar engine. Pickup goes in for what he calls a "super flush" in 2 weeks. We will see how long it lasts.

FlyingA · Dec 18, 2023

Mtnrider....Curious how this filter has been handling the heat and pressure? My 16 has started this and if I am going to flush it I would maybe like to go this route. 2016 2500 6.4 hemi 4x4 THANKS

Dren2500 · Feb 25, 2024

So. I’m not the only one with crap in my coolant after flushing. I’m so happy to hear. As the gentleman before said. These so called experts that have been in the field for so long don’t know what we are talking about. Ok. How about this. The root cause is casting sand releasing from the block. My truck started about 130-140 k I’ve put 4 heater cores in it. A Radiator and water pump. ROOT cause need some way to seal the inside of block with some sort of liquid. Something similar to the way AMSOIL and Royal Purple does to the inside of the oil passages. It forms a coating of sorts and allows less friction???????? Any ideas ?? External filter won’t work because of flow and pressures. Not enough. ……..Thinking outside the box here. So ….. how about a another tank similar to the overflow tank that can have some screen in it that can be taken out and cleaned then replaces. It would almost have to be on return hose out of engine to radiator ????????! Maybe ??? Anyone else ??? NEED HELP. I have a 3/4 Ton paperweight that I can’t use in winter

Same issue the old ford power strokes had back in the 80's and 90's. Going back through this thread alot of the images look more like using the wrong coolant or very hard water as a mix as it was obvious scale buildup Seen very few that were actually sand

^^^ this
Both the Hemi and Cummins engines are effected by this issue. The odds of two different engine assembly lines being effected by leftover casting sand lessens the odds, especially with the numbers of heater core issues reported. Should also add the 5.7 and 6.4 Hemi are both built in Mexico, the Cummins in Indiana
