I also read that some Mack trucks had the same issue too.

Service bulletins is at least what they used to call, issues such as this.Recalls are for safety issues, not comfort.
Holy cow how big of an issue is this with these trucks...... ughI flushed my radiator/entire system about 20 times before I stopped getting sand/crap out. Took a week. I would drive it 30 mins every 3rd flush. Used cleaning agent 3 times. Then went and did heater core again. Everything good now.
Sometimes you can flush it till the core leaks and it still wont unclog it. Mine did. Replaced core and 1.5 years later I have to flush it every few months to keep heater working half as__. Awhile back I ran approx 75 gal thru core. Needed to do it again in just a few monthsHoly cow how big of an issue is this with these trucks...... ugh![]()
Where is all the material coming from that's plugging it up?Sometimes you can flush it till the core leaks and it still wont unclog it. Mine did.

Truck at 111k when purchased.Looked to be clean coolant. That fall had weak heating. Flushed,and again next spring then in summer. Core started leaking and replaced it.Mechanic flushed before installing new core.I made it thru one winter good heat. Flushed it again,lasted few months and low heat again. Never seemed to get any contaminates from the system that we could see. On a warm day maybe soon I'll flush again and see if I can make it rest of winter with good heat. Needless to say I'll never buy another vehicle from this carmaker.(It will always heat good on passenger side).Where is all the material coming from that's plugging it up?
I've been told the cores lay at a approx 40° angle and contaminates settle in one half of core. I reversed hoses to try to back flush several times.Drove it maybe 500+ Doesn't seem to make any difference.I've flushed core separate from engine,then flushed engine numerous times with either no results or results that doesn't last long,even with new core. I'll not ever replace core again even if I have to go without heat at all.It always does heat on passenger side. But I'll use another truck for good heat on very cold days instead. Sad,sad quality from RamI have to wonder ................
Is the sand coming from the Radiator or the Heater Core
Has anyone cut the Heater Core into quarters, after they bought a new one.
Is the core a simple Cross Flow or what
Mine is a 2013 and runs great otherwise @ 235k now. There is no excuse for issues such as this core problem for sure.This is another one of those very bizarre things. As I go through this forum, I've seen several cases or discussions on this topic. The underlying theme seems to be there. Some concern in the casting of the block. I guess, I don't know? Though is that if this is in fact the case then why is it not happening to every truck?
Additionally, it seems this is an issue with both the 5.7 hemi and the 6.4 hemi, but I don't know if that's true?
Yeah I've only had my current 2016 2500 for a few weeks now and had I have done a little more research before buying this. I probably wouldn't have. That said, I think any vehicle. If you do enough research on via web forums, you would never buy said vehicle.
I don't know though. Maybe there are some that are definitely less problematic overall. Though I may be completely fine with the one I have or it could be a complete **** I don't know yet.
If you knew it had an issue,why didn't you add a coolant filter to it.Seems to me that'd be the common sense way to do things,but common sense seems to be a rare commodity these days,i guess it's easier to get on a forum and yell and throw a temper tantrum then actually use common sense to fix an ongoing issueMine is a 2013 and runs great otherwise @ 235k now.

If I was aware of that possibility I would have. Do they make them? But even then how much sand can still be in a system? I believe more than likely its just crappy core design and crappy coolant design. I'll drive it till I dont need it and scrap the whole pos anyway. I'm not "throwing a fit". But the fanboys may get their panties in a *** by my posts.

I know nothing about a coolant filter for the Ram trucks. If it makes you have a better day I can maybe install an oil filter inline.You've been a member since June 2019 and you have 1565 posts,so don't try and pull that one bud,you've seen this thread several times,so don't try and play the dumb card,it ain't working
Casting Sand: 6.4 Hemi HD Coolant Filter
PFA. I’ve noticed a bunch of people dealing with casting sand in their coolant that clogs up their heater core. Seems to be a big enough issue with the penstar that there’s a class action lawsuit over it. I’ve got a continuous flow of casting sand in my 2014 2500 6.4 w/140k miles I’m hoping...www.ramforum.com
