RAM 6.7 L Cummins 2500 Coolant Change.

Very easy. Draining and refilling coolant in 4th gen ram diesels. This is a stock 2014 RAM 2500 diesel.

[@desertdog2282]

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

Yea, I only added coolant once after it cooled completely down. Very easy job.

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.

[@KurtDarrow]

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.

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.

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.

[@MarionBlair]

Yes, same.

[@refugiopoint]

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.

[@taddbitofvideos3974]

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.

[@noahsmadda8828]

Yes good point on the flushing, I was wondering the same thing, and what is the process for this? Straight distilled water or coolant /water mix?

[@MarionBlair]

Yes, I did it early. Suppose to be 10 yrs or 150K. I'm on 8 years. I just wanted to make sure it didn't have any of the crap you talked about. I got 5 of the 5.6 out so I didn't flush. Ideally, I could have refilled with distilled water and diluted that .6 gals left behind and then drain. Water is the only flush I'd use, no chemicals flushes.

[@taddbitofvideos3974]

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.

Vacuum fill is what I’m doing on my 08 6.7 deleted but I filled this way once and took for short ride and I know I have air pockets in mine heater don’t blow warm air now and temp fluctuates on which way you turn. If u don’t vacuum fill you will eventually crack egr if u still have it

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.

[@alittlebitofeverything5090]

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.

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

[@jbrous3602]

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.

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.

@@MarionBlair yes I do. Took it off while I drained the coolant. Also have a little set screw looking thing on the coolant pipe by the egr cooler.

[@crod-i3n]

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.

[@James-ts5do]

CR . Exactly where I'm at with my 2014 RAM TDI after changing the upper Y connector....filling reservoir and farting around with slight Y leak... here's what I've experienced...when too much coolant gets added to reservoir and you try to burp the excess air out of the system by squeezing the upper radiator hose either: 1) With filler Cap ON any excess fluid flows over an internal channel near the top of the filler neck into a front facing secondary chamber and eventually exits from the "spot right in the bottom front where it leaks out" as you stated; Or, 2) With filler Cap OFF and you squeeze the excess fluid bubbles/escapes out over the top of the filler neck and makes a mess of engine before hitting the ground below ....Trust me I know...

[@MarionBlair]

Yes, I know what you are talking about. When the cap is off, and you overfill, it would run out that bottom thru that compartment. When you put the cap on, the o-ring in the cap seals that off and allows the tank to pressure up. If the pressure gets over 21 psi, it will let the pressure/ coolant go out that same place. That's so it doesn't spray out the cap itself. It does the exact same thing as the older models with the radiator cap and the rubber hose overflow.

[@rpsmith]

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.
