😊 Just wanted to give a huge thank you for this video! Took me about 4 hours of work to get it out after watching this a couple times. Couple notes.: The fuel rail comes out nicely with those T40 torx bolts if you take out the 11 x 8mm bolts around the manifold first to give it some wiggle, and use a long handles ratcheting bit wrench. Im a huge fan of the Vim brand of these (amazon) I have the 5 inch and 8 inch.They are not cheap but Ive never broken one yet. My other tip it put a bright ziptie an evey connection youve broken open. (Leave the tail on it) you wont miss a connection when reasembling. I took an extra step and ordered a new manifold after serning others on here. It''s not going to be in for a couple days.... Ill put it back together when it comes in. Subscribed. Cheers K

Thank you for this video! Dealership wanted $4000 to complete this on a family members car. I wouldn't have been able to do this repair myself without watching this video first

[@tworodsdownunder]

While using your other videos to find a faulty cat temp sensor I found coolant running down the trans, can't see where it's coming from though I suspect the valley is it. Thanks for taking the time to upload this video too, I'll be ripping apart the endless amount of gear feeling your pain.

[@mikekaplan4083]

I just booked my 2015 in for this replacement and prior to seeing this couldn't get my head around a minimum two day service. I think a mechanic should be safely looking at three days to include emergency surgery and counseling. Wow, an amazing video!!!

Its not too bad once you have done say 50 of them.

[@brendenbanks9293]

@@GDLautoblog yeah honestly i just got done with this and it's not terrible... only 1-2 really pita things. The rest is just tons of disconnecting. the turbo inlet is the worst of it. Everything else comes off pretty easy... there is just A LOT to take off.

I bought an older 2006 WH CRD and I needed counseling immediately. It the one with the Merc motor, and its really put me off buying any modern Merc stuff. Too many plastic parts and ridiculous prices of OEM parts. $450 for an OEM thermostat for example.

Hi, great video. Can you please tell me if it is possible to remove the intake manifold of a 2013 Grand Cherokee Ecodiesel without removal of the turbo. Unfortunately the turbo air inlet pipe does not unbolt as you show in your video and I'm not sure how to get the intake manifold out. They clearly realised this was an issue on the earlier versions and changed it for the US and facelift models

[@darrindown7277]

thanks danny great vid just started my issue keep up the good work 👍

[@franklincarreramontoya606]

Cut a T40 torx bit in half wrap it with some thread seal tape and use a 1/4 spanner with some extension to make it longer. Easy way to crack those bolts on the rails. I did mine this weekend. Thanks for the video. Impossible task without watching it.

[@michaelchambers8861]

I did the same as you last night, apart from the thread seal tape! two of the bolts were very tighe, my poor 1/4 would not have liked it so I kept tension on it while I used a hammer and punch to assist it.

Hi I am just replacing the turbo coolant hose with a complete steel braided unit, do you have a tip for accessing the banjo bolt on the turbo behind the heat shield without having to remove the turbo?

[@GDLautoblog]

Your not going to like this….. remove the engine. You have to drop the motor out to do that

[@SuperUltimatedrifter]

Thank you for doing this video, I'll be doing this today in the UK. The hose is 3/8" or 9.5mm internal diameter 👍

[@SuperUltimatedrifter]

Took 3.5hrs to get to the hose in the valley, which had literally disintegrated at both ends and fell apart in our hands. The torx40 screws came off on the fuel rails by removing bolts for inlet manifold allowing for a little movement then using a slim ratchet driver with a torx40 cut to about 12mm in length. The inlet manifold is a bitch to get off and a bitch took put back on.

[@michaelcawley3178]

Hey brother. So I got it started and had to replace the fuel injector return line. I’m still getting a leak from the rear of engine compartment dripping down to the drive shaft driver side. Also it’s now giving me a glow plug fault code on #6 cylinder. Any ideas was could have broke?

[@michaelcawley3178]

It almost looks like it may be coming from the back of the fuel rail on the driver side.

[@GDLautoblog]

As an educated guess I'd say most likely the EGR coolant pipe

@@GDLautoblog it’s definitely fuel leaking. I think not replacing the lines was a mistake for me. I don’t think I was able to get them seated right. I went ahead and ordered a new set of high pressure lines. Will update the outcome once installed.

Jeep advises to change them every time. you can get away with reusing them.

[@allanclark8631]

Great Video, Inspired me to check my Turbo "Hose in the Valley" My 2014 Diesel has done 238,000k so after hearing all the stories thought it a good idea to check. Over the last few days have got the Manifold off and the hose looks ok, soot not as bad as some but it does mainly country driving and not near a decent Jeep Mechanic. I bought the Dorman Braided and crimped hose which means removing the Banjo Bolt on the Turbo end. Mate please is there an easy way to get that off seeing the Oil line is in the way and looks impossible to get off. Your advice would be much appreciated.

[@GDLautoblog]

Requires the turbo to be removed which you need to remove the motor from the car to do.

[@steveowen8884]

Dorman makes a aftermarket version of this hose with a braided stainless hose for the flex section 667-562. I had the dealer install this at my expense, since I didn't use the factory part:(. Sadly the day I got my rig back, it developed a big oil leak. What is the oil line you refer to in the video? I see there is a turbo oil feed and turbo oil return, but dieter of them appear to have a rubber section. Any thoughts on what my oil leak might be? Thank you for your vids. I might just have to start working on this my rig myself!

[@michaelcawley3178]

Is this the same on the 2014 ram ecodiesel? I’m almost positive that is where my leak is coming from. Great video by the way.
