RAM Truck 6.4 Hemi Water Pump Replacement

[@Turbrewski]

Do not have to pull the intake. Just tap down on the water pump as you pull out, clean tube and put it back. Also do not have to pull the alternator, we just did this job. You had me stressed out too lol. Nice video.

[@mannymendez7504]

That's good to know was thinking of splicing a rubber hose for that

[@jameshorn868]

This video was a big help. Just had replace my water pump on my 2018 Ram 2500 6.4. Your step by step was a life saver. Only had one major issue. The fan clutch tool did not work hard to buy the entire setup, pump, clutch and blades. Other then that God send

[@ReignitedAuto]

Sometimes they are really welded on there! Glad I was able to help otherwise 👍

[@donsmith6036]

I just did one and didn't remove the intake, once the pump is unbolted it will slide down off that tube and back on the same way. I also didn't remove the dr side inner fender weld to drain the coolant.

[@ReignitedAuto]

I made this video quite awhile ago, seems like many people are using that technique now and it's working out for them. Anything that speeds this process up is good by me! 👍

[@jamesalexander949]

This is why I stick to chevy. I watched this video to do a truck w/p on a 4500. Makes me glad I am a chevy owner. 6 bolts on my LS waterpump and no intake removal required

[@ReignitedAuto]

The 5.7 Hemi water pumps are very easy, but on the 6.4 they added the EGR cooler under the intake and that one extra hose makes this job a real pain in the butt.

[@SonsoftheRevolution1776]

Nothing about the hemi is easier than working on the others.

[@Ramalona56]

I cut a 10mm drill bit and used a 1/4 wrench to remove coolant tube. So i was able to remove water pump without removing intake manifold

[@billythornton4071]

I have done 5 of these without removing the intake man. Just use a stubby 10 mm to remove the retainer on the tube and be very careful not to drop the bolt into the manifold. Might take a lil bit but with some patience, if i hack like me can get it then so can you :)

[@Pappy412]

Thanks for the link on the coolant vacuum bleed.. Great tips on water pump change

[@ReignitedAuto]

Thanks Carl 👍

[@MM_in_Havasu]

Got 122,300 on my 5.7 Challenger(similar water pump), water pump still works great and no play in front bearing. I keep a new one on the shelf as they have been known to fail a bit more than normal.

[@ReignitedAuto]

Yea for awhile there the Hemi water pumps were definitely an issue. Got to the point where the factory ones were backordered 6 months! Put us in a really strange spot for awhile because we were putting in aftermarket water pumps under factory warranty!

[@DL101ca]

That was no giant dead bug, it's the Scatpack rumble Bee edition. I had the exact same one in my rad. Chrysler includes one for free in every Hemi leaving the factory.

[@ReignitedAuto]

😄

[@SteveM0732]

Looks a lot like how the water pump replacement went in my 5.7 (except for the intake of course). If only removing the fan had been that easy for me!

[@ReignitedAuto]

I'm telling you, that tool is the best thing I've ever bought! It was my first "professional" tool I bought 10 years ago, still works perfectly. 👍

[@crustyzs6885]

I had fan off in 5 min with a screw driver and a wrench

[@bryonhunter1637]

I would have changed the rubber hoses under the intake for the erg valve they are notorious for leaking.

[@ReignitedAuto]

@@tomclark3592 ouch 😬

[@The3chordwonder]

Man, I think once I removed the Intake Manifold, I'd fabricate a new pipe that as a clamp mounted so that you don't have to remove the IM the next time. Also, regarding running the tap through the threads to clean them up -- if you don't have a tap, you can make a rudimentary thread chase by taking a bolt with the same threads (Probably m6x1.0 but check first) and then take a grinder and cut 2 or 3 slots lengthwise up the bolt. Clean out the grinding particles, and then thread that bolt into the holes. The grit will accumulate in the slots when you unscrew the bolt. I've done this a few times with bolts like head bolts where getting a thread chase that deep is difficult and expensive.

[@ReignitedAuto]

Nice tip! 👍

[@Jim-l9n3x]

No need to pull the intake unless the hoses or egr cooler is leaking. I get the alternator out of the way, use a special hose clamp tool to slide the clamp back, cut the tube and bracket with a recip saw…. The small 10mm head bolt is a little work but it’s better than removing the intake.

[@tomcooper920]

How similar are the 6.4 and 5.7 water pumps? I have 2-5.7s (one an '06 and the other a '17) and an wondering if I will need to remove the intake on them to do the water pump.

[@ReignitedAuto]

Nope, the 5.7 water pump are cake, no need to remove the intake. They have a similar coolant tube that goes into the top of the water pump, but you can access the 10mm bolt that holds it in place and just slip the tube out to replace the water pump 👍

[@tomcooper920]

👍

[@DL101ca]

If you don't tow or live in a hot climate , you can simply remove the clutch fan assembly and your pump bearing will last quite a bit longer not having to support the extra weight. I replaced mine with an electric fan from a V6 model but it will work fine with the AC auxiliary fan in there.

[@miles8777]

Hey man Thanks for the Video got my water pump replaced about 2 months ago and install went great. Yesterday I parked the truck and came back out 10 min later to find a constant coolant drip and huge puddle on the ground. Thinking it may be the egr coolant tube under the intake manifold because I can not see anything leaking?? Will the intake manifold come off without taking the fan and shroud back off? That was the worst part last time..

[@michaelkoerner4578]

Why do you remove the intake? I've always just popped the charge line to the intake off

[@benjaminlewis8361]

Help!!! I got a 2017 2500, 6.4. The wiring harness on the back has some kind of lock or latch in the rear in the middle. I can't see it and I can get it to release the harness from the manifold.

[@ReignitedAuto]

That's likely the connector for the SRV actuator. Don't pull the intake too far forward or it will break the connector and those actuators are expensive. The connector has a safety lock on it that must be pulled down first before it can be disconnected.

[@artvasconcellos1413]

I have a 2015 Dodge Ram 2500 power wagon, is this the same?

[@ReignitedAuto]

As long as it's the 6.4 and not the 5.7 then yes. 👍

[@mikechapman4767]

Unrelated/related question: do you have to drop the pan on these 4wd 2500 6.4's to pull the oil pump? How many hours would you put the swap at? You have me debating doing the hellcat pump swap in my 6.4 truck.

[@ReignitedAuto]

You do have to drop the pan, yes. This is because you have to get to the rear bolt holding the pickup tube in place. I have heard of people simply bending it out of the way to put in a new pump, but I can't condone that. I'm all for finding a shortcut, but not like that 😄. Time depends on skill set. If you've never done anything like it before, give yourself a full day to do the job.

[@mikechapman4767]

Thanks for the prompt reply! Thankfully our Hemis have been extremely reliable so most mechanical knowledge is LS based.

[@hammerhead6537]

Thanks for another informative video. I have a question, have you ever changed sparkplugs on a Hellcat? The passenger side seems to be, lets just say a nightmare. Semper Fi, USMC.

Hi, can I ask what that thing the coolant tube is hooked to under the intake?

[@ReignitedAuto]

It's the EGR cooler, they hide it under the intake manifold. 😕

[@carlospastran3527]

I know it's a stupid question but can the water pump be pushed down to disconnect the tube and then out?

[@joeperry8518]

Looks kinda intimidating at first but not too bad of a job just time consuming getting to the part you want to replace, helps when you have a video that shows you what to do😀

[@ReignitedAuto]

I like the 6.4 engine, but they definitely made a few things more complicated than they needed to be!

[@charlespullan4102]

Torque and pattern on water pump? Sealant or no on gasket?

[@ReignitedAuto]

No specific torque pattern, 18ftlbs and no sealer since it's a silicone seal that is designed to crush as you tighten it down.

[@mattdavis7260]

I have a 14 with a 6.4. I need to replace my pump also what do you think about aftermarket vs oem. I have about 150k on it

[@ReignitedAuto]

There's a few parts that I would rather use factory on, the water pump is one of them. I just think of it as, the factory pump made it to 150k so just replaceit with a part that'll go another 150k 👍

I found the trick to getting this water pump off without having to take the intake manifold off. Didn't damage or break anything.

[@willdog3]

How did you do that?

[@reytorres6767]

How??????

[@alexandersabido1106]

You can remove the tube off the water pump once the pump is loose. I didn't do that though, what I did was clamp the hose clamp and unbolted the small 10mm nut holding the metal tube with a small wrench. Took time but I was definitely not pulling my manifold off for a water pump.

[@Fore-Four-Dee-Too]

Couldn’t you slip the EGR water tube out of the water pump rather than removing the intake manifold?

You think 3.4hr for doing this is right? Including the new coolant, start to finish.

Sounds about right to me

[@e.l.9589]

My 2017, 6.4 just had the water pump bearing seize a block away from a dealership. They called me with a 5 hour, $1,600 quote but would settle for $1,300. Independent shop quoted $990 with OEM parts.

[@ReignitedAuto]

Yep, that sounds about right. The difference is probably due to less labor rate for the independent shop.

[@e.l.9589]

@@ReignitedAuto went ahead and got the thermostat with it as well, kind of regret not doing the hoses at the same time. There seems to be a shortage of independent parts, I prefer OEM for the most part. Thank you for the great content.

What are the tq specs for water pump and intake

[@ReignitedAuto]

21 ftlbs for the water pump to timing cover bolts, Intake manifold bolts are 9 ftlbs

[@mattdavis7260]

@@ReignitedAuto thanks I really appreciate it

[@DependableAutoTruck]

so you simply cant remove that tube and save the time removing the intake

[@ReignitedAuto]

Not on the 6.4 truck engine no, the bolt that holds the tube in place is directly underneath the intake tube. You might be able to leave it bolted in place and wrestle the tube loose from the water pump by pulling down on the pump, but not sure if there's enough room for that. I just went by the factory service directions for this video 👍

[@ianoliveira4751]

That's how I did it need a 10 mm offset box wrench and you can just barely get a turn at a time

[@kellyjohnson7208]

So the intake has to come off for one hose clamp and one 10mm bolt!? What a pain! That adds so much more time to what should be a pretty straight forward job. 🤦😠

[@ReignitedAuto]

After finishing the job, I realized you dont have to remove the clamp, just the bolt. But that bolt is directly under the intake tube 😔

[@PIWallAutomotiveInc]

There is NO need to remove the intake to replace the water pump. I've done many of them

[@spartan844O]

Then how?

[@michaeldepalma5016]

Great video but the intake manifold does not need to come off. Undo all water pump bolts and it will give you enough room to slide right off by simply pushing down on pump.

[@twowheelsdown5202]

Good video but you do NOT have to remove the intake manifold

[@ReignitedAuto]

That's correct, in the three years since I made this video I figured that out 👍

[@m35a2ww]

I looked for a vid on how to do this in a friends 3500 RAM, Dodge, whatever. Very informative. Glad I don't own one. BUT, get things right. The bolts aren't 8mm, 10mm, 12mm, 13mm, that is the size SOCKET you are using! They are 6 and 8 and 10mm bolts.

[@bernie472]

Yikes! Having to remove the alternator, AND the intake manifold just to remove the water pump? Man! My 14' Charger isn't as complicated. Just remove the pump, no sweat.

Chrysler Engineers make it so difficult for the consumer so they cannot work on their own vehicle so they make stuff for you to bring it to a dealership or a career mechanic to fix things. Grrrrrr that sure stinks

[@tony33967]

They don't include the egr cooler tube on the pump because you can pop it up and avoid removing the intake. I fix a fleet of ram 3500 6.4s. They're garbage 😉👍

Remove the intake and replace the egr cooler hoses with silicone though 🤣🤣 they pop after you overheat
