Thanks for the kind words. Glad it helped.

Hope you get it all back together with no issues. It's always a worry when you get into an overheating situation. So far I've had it happen twice with no apparent long term consequences. Once when the radiator failed, and once when this stupid plastic piece failed. Best of luck.

Glad it helped. Good luck with the repair.

Glad it all worked out for you. Thanks for commenting!

That's great to hear--Glad I could help.

Hope the repair went smoothly. Thanks for watching and commenting.

Yes the air purge is an art with which I've struggled myself. I got one of those funnel contraptions that locks on top of the radiator. Seems to have done the trick. Time will tell. Thanks for stopping by and commenting.

@@RickRose got it done. Ended up being SUPER easy to do. Was even able to save the old hose to the assembly (did a good inspection on it first before I kept it. Had to purge the air again and add close to a gallon of coolant from when It burst🤣. This video helped a lot, appreciate it🙌🏽

Also I must say the blue piece for me wasn't very helpful due to the clearance for my assembly. It got stuck up in there and getting it off ended up being a task in itself🤣

Good information--Thanks for sharing!

I was wondering about that. Mine is a frontier. I guess I'll just attach it directly. Thanks!

Exactly. Did the same for my 06 Xterra. Nissan used that same part on 3-4 vehicles that only the pathfinder needed that rear heat

I was going to post the same info when I came upon yours. My xterra 2005 burst a few years ago, so I went to the dealer to pickup the part. When they brought me the part it didn't have the purge nipple on it and it was completely blocked off like the old one you see in this video. I ask the guy about it and he said that the purge valve was eliminated and wasn't necessary. Then I said well i don't need the part then, but he said I still do to make it work. I just walked out and went home. Got out my tools took off the plastic junk and connected directly to the core line. Been that way for at least 5 years now, as well the return was replaced a few months before the the inlet went. Great truck poor material including the radiator, replace that about 1 1/2 years ago too. Top is plastic and cracked. Went with an aftermarket because Nissan want to much for another plastic junk.

Yup my plastic housing exploded when I was out on the trail i just bypassed that shit

Thanks for sharing your experience!

Same here. The new blue-clipped clamp was too big but I got it back on with the original clamps. We'll see how it goes over the next few days.

Glad you caught it in time. Thanks for stopping by and commenting.

Sorry to hear! A mechanic later swapped mine out for a regular hose clamp because he noticed it leaking while working on something else.

Well as an update I took the truck to a mechanic for something completely different, and the mechanic observed leakage around the snap ring. So he replaced it with a regular hose clamp. That was just a few weeks ago.

I seriously thought about doing that but wimped out. Glad it worked for you. Thanks for stopping by and commenting!

Rick Rose my father in law is a mechanic. That piece is not a control valve of any kind and the fluid runs right thru it. Attaching the hose to the firewall seemed to East a fix but we did it. Attaching it was difficult because of limited space. I later came across an article of someone doing just what we had done pointing out that nipple on top was for rear heat in a pathfinder. The new part doesn’t have that nipple. Fluid runs thru it so why even use it?

Ha ha that seems to be the go-to solution from the comments. Glad I could be of some help. Thanks for commenting.

Not sure about a grey clamp, but I will say I wound up replacing that blue plastic one after it allowed a leak to occur, months later. Standard metal one worked fine.

Just finished. Took all of 30 minutes. I was referring to the clamp in the middle between the rubber and aluminum. I wound up using the original hose clamps for the connection. The one with the blue clip was too big. Otherwise, stock from parts store; it came right off and went right back on.

You DO NOT have to take the dash apart if this part is what failed. Yes, it is a matter of getting the old part off and the new part on, all under the hood. Getting the old part off might be a challenge for someone who never messed around with clamps and whatnot. Good luck.

Ya, i figured the guy was not the smartest who suggested that. Lol This problem is SUPER common im seeing and im glad this one video exists. I have the blue clamp holder secure on my part lucky lol. So to paint a picture of the process....after wrestling the old hose off (i assume ill have to cut it toward the top like you did). After its off slide the new hose part on the bib. Pull off blue thing to secure clamp. After that is just connecting the other aluminum end to the coolant hose and clamping securely? Bada boom bada bing? Im trying to step by step in my brain cuz to someone who never been under the hood its scary lol. My Xterra has the same year and same milage as yours. The failure is a few months apart. Wild. As for the clamps im not as worried about those because im a gunsmith and i can tell they are a SOB. Just a like strength and finesse i should get it done in like 20-30 mins no? Its also raining here in northern Ca. -__-

@@gacylikesbrutal Yes--Get the old clamp off, then you'll likely need to slit the old hose off with a razor knife. The hardest part is getting the old part off. The new one should go on easily. 20-30 mins is a reasonable timeframe. As for the rain--I finally built a garage and hope to not have to deal with that problem again. Again, good luck!

Hope the repair goes well for you--Good luck!

@@BlvckWolfGames Hope you're back up and running quickly.

Thanks! For amazon links, expand the description section. There may be some broken ones in there since the video is older, but I checked the top one at least, and it works. I think the price doubled since I made the video though--It's showing as $43 and change. It doesn't hurt to check your local parts store either; they might be cheaper. Good luck!

Thanks Rick

Someone in the comments down below said they were able to do that. My only worry would be stretching the hose. Your call on that!

@@RickRose hi thanks for your reply , so after I wrote the question to you I couldn’t wait for the answer as I was writing to you and looking at the pipe at my car in the same time 😅 anyway I couldn’t wait for the answer so I just inserted the hose directly to the pipe and it fit just perfectly no stretching or anything I secured it with the clamp and wala the thing work just fine I still don’t get it though why the piece in the middle is there from the factory I mean I can’t think of any purpose for it , all other cars hoses goes directly to the heater pipe why the xterra is different 😂, I had a crazy theory but it’s too long to explain it’s involved the corruptions happened inside Nissan company and it’s look to me the piece was pushed to vendor contractor that gave good amount of money to someone at engine cooling design department to have the contract for him and because it’s small piece the chief designer didn’t pay attention for it , I’m 100% sure it’s inside job because I know for fact that Nissan is the most corrupted company in Japan . I mean come on look at Chevy and Chrysler and even bmw and Mercedes they still do direct hose to heater till this day 2022 .

@@RickRose I just don’t see any use for it .

@@RickRose the pipe was 3/4 and the hose was 3/4 also I swear they did thought about making it same size from beginning but someone just decided to ad the piece to get money from the vendor who got that piece contract, made in China at 5 cent each sold to Nissan for $1 each . 1 million pieces made from 2006 till 2016 $1 million dollars or even more .

@@sabahjason1 Glad it worked out for you! Thanks for sharing your experience.

I think you may be on to something there--Once I saw that the part was straight-through, I wished I had tried a straight connection. Thanks for watching and commenting!

I just did the same thing lol

So I can just insert the hose to the heater core pipe directly right ? I’m confused too why we have to put this piece In the middle?

Good to know!

Both great tips!

@@RickRose sorry 1 inch PEX not 3/4

I totally get your point. Problem is, if I raised my production value, I'd have to up my admission price. :^)

I have not replaced that part yet. Sorry I can't help, but best of luck.

Ouch! Hope your engine is okay.

Mine was on Amazon--I put a link in the description; hope it still works.

Mine went out now a few months back, towards the end of 2019, was leaking but hard to figure it out, i saw it after some, hmmm, a lot of sweating on my part. gauge would go HOT when i was stopped somewhere, but cooled off when i was driving, and that would drive me crazy, well, more then normal. bought part, and hard part was getting if out from behind engine, and next to firewall. but i did it, wasnt really too bad. i am right now 110,000K and figure to replace the other with Aluminum way before it goes bad, why wait, cost aint too bad, under $25 on ebay. wasnt easy to find on ebay though, [ www.ebay.com/itm/APDTY-141371-HVAC-Heater-Hose-Connector-Fits-Nissan-Upgraded-To-Aluminum/233676943697 ]] there is no pic of it, but description is exactly the same as the one listed on AMAZON. well, it is 4months, have ya replaced it yet?

@@lecyalphamaids9134 No not yet! Good luck with the eBay part.

Coming out of the reservoir? My guess, and I am not a mechanic, is that you had an air bubble trapped in the system. Once the bubble boiled its way out, the level should have dropped, allowing you to add more coolant. That's again my best non-mechanic guess.

Great to hear! Thanks for stopping by.

That was the only one I could find a year ago--Options may have changed.

Dorman on rockauto.com its aluminum

Sorry for the late response--Missed this one somehow. I did not perform any sort of bleeding procedure but have since wondered whether I should have. My truck won't warm up unless it's being driven (won't warm up in the driveway), and I've heard that's a symptom of air in the system.

Yes as I recollect I used a needle-nosed pliers to remove the clamps--I really wished I had the specialty pliers I mentioned because the clamps were a pain. I used a utility knife to slice the old hose that was basically glued to the barb coming out of the firewall with old crud. That's all I can remember at the moment. The hooks I bought were useless.

Michael, I think the part you are talking about is the heater core outlet assembly, which is this: Genuine Nissan (92410-EA200) Heater Hose amzn.to/2PavJ0P Does that look like the right part?

@@RickRose or this could be it, same same i think, ebay or amazon. i buy my parts mainly from ebay, what reason i dont know, oh ya, my wife pays for it thru our PAYPAL. www.ebay.com/itm/Dorman-626-598-Engine-Heater-Hose-Assembly-For-05-19-Frontier-Pathfinder-Xterra/193490632980?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D225074%26meid%3Da9ab1eae7ce7494390b6e89476a2c3f7%26pid%3D100005%26rk%3D3%26rkt%3D12%26mehot%3Dco%26sd%3D371423823106%26itm%3D193490632980%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebWithBBEV2bGenderDemotion%26brand%3DDorman&_trksid=p2047675.c100005.m1851

I believe it's this: Genuine Nissan (92410-EA200) Heater Hose amzn.to/2PavJ0P

No but you could sure smell the steam from the spray on the motor and manifolds. If you smell coolant in your exhaust I think that's a more serious problem unfortunately, like a blown head gasket.

Sorry, thought I explained that. Since I somewhat stupidly removed the factory clip retainer prior to reassembly, I was forced to use pliers to hold the clip open whilst I jammed the hose over the bib and thence the clip over the hose. It was harder than it needed to be, because of said stupidity. If you leave the retainer in place, you should be able to easily slide the hose over the bib, pop off the retainer clip, et voila! You are nearly done.

@@RickRose I think what he may have meant to say, what ya do if it does not come with the blue clip. i may be also stuck not knowing if ya dont make another video showing how ya did it, i am fixing to order it now. been years being a SATURDAY mechanic, and i have already some thoughts on how to get it out. hmmmm LOL but please wish me luck anyway....

What is the name of this part so I can order one

@@dannyfoster6754 heater core inlet valve, theres also an outlet valve

I don't think much because it is high in the system. However mine was already low due to the failure, so I cannot speak from experience concerning a full system.

@@RickRose ok thanks....just swapped it out and didn't lose too much.

The only way I knew mine was leaking was that the temp would rise, so I can't help you on the volume measurements. All I can say is, track it down quickly, because when it goes, it goes. It will leave you stranded someplace. Try looking under the hood while it is running. Good luck! And thanks for stopping by.

And BTW--Don't fool around with a coolant problem. If your engine gets too hot, it's toast. Seriously--Track this problem down or hire someone who can.

There are two hose assemblies that go through the firewall side-by-side. One is input; the other output. Can't remember which is which. I'll try to dig up the part (I bought it but didn't swap it out) to grab a number for you tomorrow. But if you do a search for heater hose assembly for your year XTerra, they should both pop up.

Oh heck, I just saw that both parts are in my description above. Click on "read more" up above and you should see the links.

Unfortunately I don't know the answer to your question. If you can't find the answer on the web I would ask someone at the parts store.

Rick Rose no problem i just custom fitted a hose and it actually looks and works fine 👍🏼

Sorry to hear. Hope the repair goes smoothly.

@@RickRose thanks! I just removed it totally on my Frontier. Seems to work just fine.
