You’re a smart man. Obviously learned how to communicate what’s important and how to avoid the stuff we don’t need to know. I like your attention to the important details. Thank you for putting all the effort into your productions.

Thank you sir, being retired and after watching your videos I am saving a lot of money by doing my own maintenance on my 2017, 2500, 6.7L. I’m looking at all your videos and have them all in one file.

Thanks for the tutorial Marion. I have the confidence to change mine once the truck thaws after its long winters nap. Shaky hands have alot of heart behind them. Merry Christmas 🎄

Great video and super helpful. Only thing I’d is that the coolant drain valve at the bottom of the radiator opens up a drain right next to it. You can attach a length of tubing to the drain before turning the valve allowing you to drain all the coolant into a 5 gallon bucket with no mess. I’ll admit I did take off the wheel well housing rather than going from the top, so it was easy to see everything.

On my 2012 Ram 2500 there is a bleeder valve for the cooling system on the passenger side of vehicle near the egr cooler. It is also the highest point in the cooling system. Opening that vent will help to bleed the air out of the cooling system. Thanks for all the videos. You have saved me a ton of money by being able to do my own maintenance and by showing me how to do it correctly. Also I have to laugh at some of your off handed comments in some of your videos.

Thanks for the in depth information. I have a 2016 Ram 2500 and have changed the differential fluids and transfer case myself after watching your videos. Your a great help!!!

There is a 4th way to access the drain plug on the 2014 Ram 6.7 diesel without removing anything and is the easiest of all. Simply slide your LEFT hand between the wheel well cover and you will find an access opening in the frame to reach the drain plug. You will feel around for the plug location which is very close to the opening in the frame and then I used my 3/8" rachet with a 10mm Allen socket. With just a couple of 1/4 turns the coolant starting flowing. I would hope most diesel rams would have this opening.

Marion I found out that the hose that comes with your def fluid bottles works perfectly on any gallon jug ! Works every time great video I enjoy watching you

Just did my coolant change yesterday with your help. Flushed my heater core while I was at it too. Thank you sir

You sir are a Godsend. I realized today at work that I replaced a coolant hose during the summer and my truck had been sitting mostly full of water. Temperatures have been dipping into the danger zone, but supposed to get into the single digits tonight. I’m working 14 hour days and thought I’d be up all night saving my engine. Thanks to you I accomplished the task shortly after bedtime. Thanks so much!!!

Thanks for some great information Marion. We can always count on you for non-BS content.

Mr. Blair, you are the best! I love the Cummins engine. My best friend in life, Mac, was a mechanic and had 2 trucks with the Cummins and told me not to buy anything else.

I swear this channel has access to my fleet maintenance schedule sometimes. 🧐 Great content, great timing and easy to understand and follow. Much appreciated from SW PA 💪🏻💪🏻

Been waiting for this video before doing mine, I definitely feel more confident about doing this myself. I think i might change the thermostat while I’m at it just as a preventative measure. Thanks for the tutorial Marion.

I had to change my thermostat on my 2011 3500 CTD this summer. It was alot easier to get to the drain valve on it. Thanks for all the videos you do. I had to pee at 9:12!!!

Awesome Marion, loving these service videos.

Thank you for every one of your videos, I really appreciate it.

Well that was a lot simpler than I thought it would be. I figured there would be bleeding involved. (Not you but the truck 😂)

Hi Marion and thank you as always. My used 15' had the pump done as required before I owned it; now at 125k miles, I'm making a plan for long term ownership. I'm thinking around the 150k mark I will replace the fluid, as you just did, but also replace the pump (again), tensioner, belt, and the Y pipe (other hoses as needed). I don't care to add an aftermarket filter system, but I do want to do a certain amount of work to help with longevity and keep it out of the shop. Thanks again, and I look forward to the next one.

Greetings, finally have something to add :). I bought a used 2015 2500 Big Horn with the 6.7, about 127K miles. I'm slowly moving through maintenance items, sometimes at the dealer if cost benefit seems in my favor. The coolant was getting up there in age, so I had the dealer flush it all out, they used a cleaner and then refilled up with the same Mopar that Marion showed. Total cost in California out the door was $270, which for me was fair, I wanted it flushed and did not want to deal with disposal. Note that I don't think I have the Y flange so maybe just one radiator starting with my year, not sure. They gave me what was left of the gallon because a little burping still and the low level light would come on and off at a stop light, no big deal. Anyway, just sharing experience and cost for a "flush" at the dealer. Cheers everyone.

As usual great info presented in a matter of fact way. Thanks for sharing.

Thanks for that secret route to the drain , hopefully it’s the same on my 2016. I doubt I will change anytime soon as a water pump recall & then a turbo actuator failure has made for 2 different drain & coolant replacements( warranty) Oddly enough that funnel for the fuel fits and stays in by itself on mine . I also always carry 5 gallons of fuel in a can with a modified spout & have needed it ; ) Stay safe & be well

Great video. I thought it was going to be harder than this. I have been putting it off. Ironically I just added some fluid on my truck yesterday and thought about changing it out. Now I know how. Thanks Marion!

Great info. I have a 17 so I will be back to reference the information in a few years.

Great video brother. I always enjoy them, keep em coming. Blessing to you and your family.

Your engine looks clean like a new truck. I worked construction and a2016 was my work truck so it’s dusty and with some oil spills. 178567 miles with just maintaince And a turbo replacement.

Marion- Quick thanks for taking the time to walk us DYI types thru the paces !!! I got a low coolant warning & turned out that the coolant reservoir turned a sludgy brownish color and was causing a fault with the sensor … It was quite a chore to get the clearance to remove the coolant reservoir and replace with a new one. Did a flush and coolant change which cleared the low coolant fault !!! However, after cleaning the coolant reservoir using SUPER hot water & cascade all the sludge n gunk was gone… So, if one has the time and desire to remove, clean, replace, flush and refill… It is possible to remove the fault by a “vigorous cleaning cycle” !!! Or $800 at the dealer will get the fault cleared using Dealer Service 24k magic !!!

Shaky hands getting it done! Great job, sir!

Thank you Sir!!!! You just saved my Sunday with that 10 mm hex info. And that was well presented video God Bless

The best dodge ram videos on KZfaq. I have used this video 3 times now over the years. Thanks for all you do. 🫡

My 2015 was in the water pump recall. My dealer used the vacuum system to recharge the cooling system after replacing the water pump. After a few days, I started getting the low coolant warning light. The dealer noted on the work order that the workshop manual's instructions were followed but the system did not recharge correctly. Just an FYI. I have the coolant vacuum system and it works well with all my equipment, most diesel land management like tracks and RTVs. Have yet to use it on my RAMs but will when they come due.

Always good content. No bs on your channel keep up the good work.Hope you and your family are well.

My dealer made it easy for me when the water pump went out with about 80 k miles on it. Still under warranty . They changed it to the upgraded version where it leaks out from the housing instead of the front bearing.

Great video !!!! Keep them coming ! Super informative!

Thanks, nice work. Saved me some time on mine.

Great video, as always, Marion! Thank you and MERRY CHRISTMAS!! 👍

Very nice video. About to do my 15 3500 buts deleted out of necessity so it’s a lil easier. Thx for the effort making and posting ur work.

Thanks Marion - you have done it again!!! Great job! Oh, I like your selection on XM radio. Fox News is the best!

The Preston Dexcool 50/50 works. Has on the bottle MS 90032. Is around $16 or 17 at Walmart. I’ve had it in mine for 15k and no problems.

Another helpful video. Thank you, sir!

Great video, mine is asleep for the NW Minnesota winter. Merry Christmas 🎄

Another great video Marion, thank you!. Today I had de "low coolant" amber light on for a few second after starting the engine, so I'm looking for the right level to fill it up, can't find it on the reservoir

Great video and great explanation 👏 shot out from Brazil 🇧🇷

I never use 50/50 when changing my antifreeze! The best way to get a 50/50 mix is to start by adding full strength antifreeze up to 1/2 of the cooling system's capacity. Then add distilled water until the radiator is full and add more distilled water as needed as air is purged from the system. If you use 50/50 instead of full strength, you will end up with more water than antifreeze in your cooling system because around a gallon or so of water remains in the engine block even after your drain the system. Also, I don't recommend fooling with the petcock. They tend to break off or start leaking so I only make sure they are closed and never open them. Just pull off the bottom radiator hose and flush as many times as necessary to end up with clean water on your last flush. You can also remove the block heater and with a few plumbing parts connect a garden hose to really back flush the entire system and don't be surprised if the block heater could stand to be replaced. I was amazed how bad mine looked.

Appreciate the info! Thank you for taking the time!

My 11 model is nothing like that. I figured it would be similar. I was able to use a 3/8” hose ID and open the drain valve, drained it into a 5 gallon bucket.

I'm pretty sure the engineers get together and say" how can we screw this up?".😉

“I’ve got the rest of my life to do this” 😂

Thank you Marion. That's a great tutorial

Important to use distilled water when mixing 50/50.

Nice job. Great tips!

Actually, according to the cummins and ram service manual vacuum fill is required due to egr cooler, otherwise failure of egr cooler and overheating is possible. To many air pockets that require vacuum fill.

you are a bless sir Thank you for help us with your videos

I loved this! Thank you for the information and an informative video!

Thanks! I appreciate the advice and video how-to

Thank you Marion! 👍🇺🇲🇺🇲🇺🇲🐕

A hex socket and short ratchet wrench works better than hex wrench. Put the socket on the wrench and rotate it on the ratchet until it slides in the drain plug. It takes several turns to open up the plug and you only have to put the socket in the drain plug once.

Commenting for support

Hi Marion I wanted to ask about this for sometime, glad to see a video from you. My 18 started a weep after a cold snap last year coolant in it tested to -43c. But we got a bit cooler than that. So the dilution of the mopar coolant is rated to only -35c. That’s what the dealer put in... ended up with a way bigger leak and repair bill..... So After replacement Rad i used a different mixture now back down to -50c. Gonna try not to use it in anymore cold snaps. Thanks for the tips, I hope your doing well.

My dealer had to drain my coolant, and they did not replace all of it, I drove from S. Texas to Trinidad Colorado, and put in about 1/2 gallon, drove another 100 miles and put another quart in. So dealers don't even use the tool.

Hey Marion loved your video. Truck is also due for a brake fluid change. I hope you post a video if you decide to do it yourself. ill be looking forward to it.....

Very nice video. Thank you sir!

I have already changed the upper y connector, i think I will go ahead and change the lower Y connector. I'm having to service the Turbo Actuator so I think I'm going all the way time for the flush anyway.

We men always wiggle, shake, or push the object after tightening it down and say, “that ain’t going nowhere” 😂

just go under the truck' on driver side. it's a plug that sits on the bottom-side of radiator. mines have nub that you can twist it off to drain' and back in to close when ready to refill.

Good informative video. Thanks

Another great video Marion. I wonder if you have thought of putting a video together around fuel injectors. I've read a lot in forums about how many 4th Gen trucks need them replaced around 100-150K miles. I try to buy the Nano filters to keep small particles out of the system, but am curious on your thoughts.

Sir you are good 👍!!!

Thanks Marion...

Could you have reached the drain valve from underneath? Just wondering. And you're right, Ram engineers are very good at two things: putting parts in difficult to reach locations, and coming up with the most complicated and difficult to see locking mechanisms on every wiring harness plug in.

I have the same truck, I had the water pump recall done at 40000, I have 96k now, dealer say to wait till I have 100k on coolant, so for me 140k. Tested mine with infractor, show -38*. Just wondering why you did yours so early. And I didnt see you flush it. Just a dump and fill. Why you didnt flush it good before refill. At the cost of the coolant of 80 dollars, I will flush mine good, these trucks are known for heater cores plugging up. When they did the water pump, they flushed mine, and there was all kinds of crap in the coolant. So I had them add a coolant filter to system to help protect the heater core from plugging up. Have a good day.

Great video, as always! You are the best. Off topic, but have you noticed on the Def guages, mine will show about 90% but the banks monster guage says 62%. I think the mechanical guage reads to the dent in the tank and the banks may read from the top? Was odd, and was just wondering if you had ever noticed! Keep the videos rolling, friend.

Would help if you open the top radiator cap ? Just to help the air come out easier? Good video 👍👍

thanks for tips once again.

Thank you. I have the same truck and noticed that I can smell antifreeze in the engine bay after a drive up to temp. It uses a small amount of coolant as well from the reservoir. There are no obvious signs of a leak. I did have the water pump recall done way back and im the original owner. I only have 48k on the truck. Any ideas I really appreciate it? Thank you

Thanks for the video

Great Video, Thank You! Where can I buy those exact type of battery insulators? I can't find those anywhere. Thanks

Thx just what I needed

Did not notice if you bled the coolant bleed bolt just in front of the egr cooler. This keeps air out of the egr cooler which causes an internal leak? If you change your ccv filter at 60k, a Cummins rep says you can wait for 120k to clean the egr cooler and valve. Cleaned mine at 75k just to find the water seals too stuck to get out...so, 50k must be the way to go. I also make sure that the ccv air filter is changed every 25k.

I have always used a water pump lubricant but I don't even know if they make it anymore. Did you run a cleaner through the system. I've also open slightly a threaded plug on top passenger side of the head to get air out.

Cheaper to go with concentrate and distilled H2O.

Thank you sir, Ive been waiting for this, Ive been following your videos since I bought my '16. I use your videos so I don't have to pay out the ass for a diesel tech to do all this. I like the method of going thought the top of the engine to get to that valve. You use distilled water for diluting?

Wasn't there a "bleeder" in the vicinity of the EGR cooler? On a '17 there definitely is. [EDIT: on a '19 the Factory Service Manual says the vacuum fill tool is mandatory to ensure no air pocket(s) in EGR cooler]

Prestone says it is compatible with OAT POAT HOAT & IAT and works with all vehicles. Has anybody used Prestone in their Ram and mixed the Prestone coolant with the factory coolant???

Fleetguard ES Compleat OAT (RED) is a solid replacement. Marion: what was the total amount of new coolant - to replace old? Thanks - awesome video!

The only thing I missed did use distilled water??

Are you using distilled water to mix with the concentrate?

That sh*t got real funny from 10:08-10:50 lmao!!

I am going to attempt to explain this. Does your coolant reservoir have a spot right in the bottom front where if you over fill the coolant it leaks out. I have a 15 and my reservoir does this if it gets over filled. I am not sure if a plug or something was supposed to be on that bottom portion of the reservoir. Reason I am asking this is I see that you were able to fill the reservoir up really high while it was taking coolant in and I don’t thank i would be able to do that due to my reservoir having that drain on the bottom. By the way I do appreciate the videos you do they do help tremendously.

Did you use 5 gallons or just 4 ?

Make sure the antifreeze says HOAT. Just bought the Zerex at Advance Auto.

Thanks Mr Marion you did a great job, how many thousand miles to change the cooling? And why you don't replace the new thermostat as well. Thanks.

ORGANIC ACID TECHNOLOGY - OAT

good job gramps.... 🤠

How many gallons does it take

Once again, thank you for another fine video. (Assuming the system is at the proper level before starting the change) Would it be worth while to measure the amount that came out? I'm wondering if that would be a simple method of know exactly what needs to go back in. Just a thought. Dave

How do you put the radiator Drain valve back on when you accidentally take it out all the way?

YOU CAN SET THE IDLE WITH CRUISE CONTROL???

Great video. Enjoyed it. It’s off the subject but was wondering if you have ever had any issues with the DEF system? I have a 2018 2500. You hear horror stories on Facebook about it. Was just wondering. Thanks

I have a 2018 Ram 2500, diesel,, would you think it would be the same procedure or process or same steps to change coolant as you do on your 2014 Ram
