00-04 Nissan Xterra Transmission Oil Cooler Leak - Replacing the Hoses and Clamps (VG33E)

[@darcygriggs9694]

As a retired Nissan dealer tech and owner of 00 Xterra 4wd appreciate what you do

[@XterraRob]

Thanks my dude! Just trying to document my knowledge on these older vehicles as I encounter issues to help out others!

[@Teekay617]

Glad you still make videos, ever since I picked up my X I been following you, have a 02 that was garaged for 12 years 50k miles, been stripping it all down because it sat..Thanks! Great videos!

[@XterraRob]

For a car sitting so long...rubber hoses will probably leak everywhere! Good luck! I still make videos...just been a busy year with other projects outside of the Xterra...home improvement, land scape renovatioms, etc. Let me know if you have specific ideas for future videos.

[@Teekay617]

@@XterraRob well i went through everything no leaks just a leaky gas tank couple fuel lines, and alot of sanding. Its all under coated now, i got it last year shes on the road now.

[@XterraRob]

Nice...next video is on leaking evap fuel hoses...lots of old dry rotted hoses under the rear of the vehicle by the fuel tank. Glad yours is on the road!

[@Teekay617]

@@XterraRob Yea I got rid of all those hoses to the tank, and popped a new fuel filter in ran 3 bottles of berryman b12, only thing i gotta take care of is that knock sensor. Nobody in my town drives a X modded just runners i see or jeeps. Good stuff man.

[@XterraRob]

@@Teekay617 yeah man the modded xterra community is pretty niche...makes it more fun and unique if you ask me! Good work getting yours road worthy! Reduce those headaches later on.

[@gacastillo21]

Thanks for sharing this video. I will be replacing the transmission hoses on my '02 Automatic 4x4 xterra and this helped a lot. I have two xterras, both 4x4. One auto and one manual, both 2002.

[@XterraRob]

Happy to help and thanks for watching!

[@Thundy]

Hey, Rob! Been following ya for a while now, and I just started to get a leak on the passenger side hose. Quickly Googled the issue for the path of least resistance to solve my issue and once again I'm brought back to you! I'll be ordering those clamps direct from Nissan and grabbing the hose from O'Riley, hopefully knocking it out this week. Thanks again!

[@XterraRob]

Happy to help thanks for watching!

[@justinpappas1222]

Thanks man! I've been stressing about this on my my 03 frontier.

[@XterraRob]

Fairly easy fix...but it is kind of cramped with the fan shroud down there. You can do it!

[@synapsefiero]

You helped me figure out if my transmission coolant lines were crossed. Mine keeps shooting transmission fluid out of the dipstick. I’m getting closer to the problem. Thanks

[@XterraRob]

Awesome...did that fix your issue?

[@johnny4713ify]

Nice work! Question is the hose closest to the passenger side the return line coming from the cooler? Appreciate a reply. TX

[@officerbboyd]

Omg just like that I can do this ! Thanks

[@XterraRob]

Happy to help my man! Good luck!

[@kaylabeitz1464]

So you were just able to bypass the factory transmission cooler with no other modifications? I've been trying to find good information on this and honestly this video is the most help.

[@XterraRob]

I did not bypass the stock cooler. I plumbed my external cooler in line with it so the transmission fluid went from the transmission >>> external oil cooler >>> radiator oil cooler >>> transmission. If you want to run am external oil cooler only, it is easy enough to bypass the one in the radiator and just have the external one.

[@kaylabeitz1464]

@@XterraRob just running the external, does it cause any issues that you know of? I don't want to cause more potential problems but I'd like to increase the life of my transmission for sure.

[@XterraRob]

No issues at all...just make sure your rubber lines are the proper size and the seal integrity is good with proper clamps: IE legit spring style clamps and not the worm gear kind. Only issue would be leaks at the hoses. One other thing: if you are in a very cold climate, you don't want your fluid to be too cold. That was why I kept the radiator cooler inline so the hot coolant allows it to warm some even if it is cold outside.

[@kaylabeitz1464]

@@XterraRob I'm in Southern California so it doesn't get too cold here. No snow unless I go to the mountains and that's only at certain times of year anyway. Thank you for the help, your video are really informative.

[@XterraRob]

Sound like it will work pretty easily for you then! I used a Hayden automotive one from Amazon I think. Pretty good quality and no issues. Just measure the space you want to mount it in and make sure you get the right size.

[@Teekay617]

Hey Rob you Ever try parts from The Nissan Navara D22 they have a insane UCA set up, Im sure you know already but their aftermarket support is huge compared to ours, and it fits the X.

[@XterraRob]

Great idea!!! I have seen some parts advertised for both but hadn't thought about D22 parts specifically. Thanks for the tip!

[@Teekay617]

@@XterraRob yea check out the Tierod set up. And their front suspension, its way better quality. Heavy duty stuff.

[@TURBOINTEGRATYPER]

Hey where did you get those new spring clamps with the tap you pull off..?

[@XterraRob]

Nissanpartsdeal I think... But any local Nissan dealer can get them for you.

[@ThonyXJ]

I thought hoses were 5/8 and not 5/16 thanks for information. I will install my cooler with hose fittings.

[@doomsayer559]

Looking at the radiator, which port is the inlet and which one is the outlet for the transmission cooler? I cant find a drop of information on it.

[@XterraRob]

I was hoping no one would ask because I wish I had documented that but never did. I knew at one time because I test started my engine one time without the hoses connected (oops!) and saw which way the fluid shot out. Messy way to answer your question…but would work. You doing a transmission cooler?

[@XterraRob]

I know I plumbed my external cooler so fluid goes directly into the external cooler and out of the external cooler into the radiator based one. I didn’t want my ATF to get “too cold” in the winter.

[@marcr250]

Hi Rob, what is the Nissan part number for the clamps?

[@joelsanchez4226]

any leaking from those new clamps after a few weeks?

[@XterraRob]

Nope all dry!!!! OEM clamps are definitely the way to go here. Worm gears did not work well on the small hose. The area under the gear was flat instead of rounded, causing leaks.

[@cesarconh895]

Those stupid lines leaking killed my Jatco transmission. Don't mess with these lines if they are not leaking.

[@XterraRob]

Yeah man...its often best to leave them alone. For me though I had to remove my radiator a few times...to replace the radiator, do timing belt, etc. They had been leaking and brittle for a while...and the transmission cooler lines I added did not help at all.

[@1524mclovin]

Great vid man! so i have this same problem on my 2004 Xterra. What exact hose did you buy? Is is 5/16" Inner Diameter? I may also replace the clamps as well with OEM. Please let me know the part number of those fresh clamps! Thanks!

[@XterraRob]

Gates 27056 Transmission oil cooler hose I got in a 3 foot length on Amazon. I have another video about hose clamps in my video time line where I give all the part numbers for the fresh Nissan clamps. Check my channel page and look at the video list from last year and you should get what you need.

[@1524mclovin]

@@XterraRob thank you so much! Seriously! I’ll do just that! Gotta keep my X on the road!

[@XterraRob]

Happy to help. If you can't find it let me know and I will dig up the link and part numbers.

[@1524mclovin]

@@XterraRob id love to see your video on the hose clamps. I feel imm gonna need em when I replace the hose.
