Mine broke yesterday at the same spot and because of this video the repair replacement took 2 hours and went the exact same as this guide. This is what RUclips is for! Do as many on '05 to '12 pathfinders as you can because I will be in need as I plan on driving for 5+ more years. Thank you!
I’ll do as many as I can. Glad the video helped out and thank you for watching!
Where did u get your part plz help
Thank you so so much, it costed me $25. For the part, Nissan quoted $730. What a difference your video made for me, 😊😅 saved me a lot of money, I don't have.
This was one of the best auto DIY videos I’ve ever seen. Thank you.
Kele Pecinpah thank you for watching!
Brian- Thank you for taking the time and effort putting this video together. I was able to successfully replace our broken hose assembly last weekend using this video. Much appreciated...all the best.
As a woman, this video has convinced me that I can do this myself! Thanks a lot
Great video! Really well done. Followed it perfectly for a successful fix. Took 3.5 hours to complete. Thanks so much for doing this. Saved me some serious cash at the dealership.
Mine just broke in the same place. This is going to help a lot. Didn't realize I had to replace the whole thing.
Brian - Thanks. I should start a channel called the "Mechanical Idiot" rich with humor and curse words......my turnaround was more like 5 hours....due to just not knowing what to do whatsoever. Finally had to abandon one of the hose clips for a traditional hose clamp as it kept popping off. I'm sure that I've shortened the life of the car, my life, and the Napa auto parts guys life as i asked him to show me the schematic 20 times as I kept struggling. Damn proud of myself for following this video, I'll try to keep it in my lane going forward. Thanks again, really enjoy watching people who are awesome at their craft.
Wow. Its a bigger job than i imagined. I need to repair my 2010 pathfinder with the same problem.
Your video is fantastic instructions for this old backyard mechanic to follow. My question, if dishsoap helps install those hoses, doesnt it also help them separate? Would silicone spray do the same thing?Thanks for making a great video 😊
I just did this replacement thanks to your video. Great tutorial and the car is operational again. The problem I'm having is the heater isn't getting warm now. Any ideas on what it could be?
This vid is still educational after three years...thanks
Another great video Bryan. I've done this job myself. Lot of plastic parts that go bad.
Nice video man...keep it up. my xterra heater hose broke off after bodylift, it stretched out too much lol
Thanks so much for this video. I did this job yesterday. I wasn't able to remove the tire because of where the vehicle was positioned when the hose assembly busted. It's possible to access the lower hoses by cranking the steering wheel all the way to the left, but I don't recommend it! Thanks again, great video!
Ray Benavidez that’s awesome to work to the problem and got it done. Thank you watching!
Mine broke today. Exact same spot. Thanks for the video.
Chris Gillespie sorry your having car trouble. Glad the video helped.
Also if you aren’t replacing the axial Larry pump, should you unhook from the ekectical system ? I appreciate all your help. Trying to do this to save money.
Thank you so much my moms car broke down and this helped fix the problem =)
Curious do you always have to replace the pump? The part comes in two pieces now so would you start the same way if leaving the pump? Would it make it easier to replace the hose from the pump to the pipe along the firewall? Recommend actions please. Thank you
this is exactly what happened to my '06 pathfinder and I'm planning to follow your tutorial to do it myself. However I noticed some of the plastic bits and pieces fell back down and inside the hose. I tried to disconnect that hose from the button but it wont budge! My question is if it would cause any problems if I cant get those pieces out?
Nice dam job without any B.S. talk , I love it ! ! !
5 star video
Jimmy Erbe Glad you liked the video hopefully it helped get your ride back on the road. Thank you for watching!
this happend to me on my pathfinder 2008 wtih 160k miles. insted of replacing the hole assembly i just broke the rest of the plastic hose connector at 1:57 to reveal the aluminum tube. then i bought a "T" radiator hose connector and use JB welds to make it a permanent install.
hi, i have the same problem, can you tell me what is the part names, part numbers and where did you buy the parts... please..
@@damesiojohns7176 i just used a 'T' heater hose connector, some heater hose that fit the connector, and hose claps form autozone. i used a heat gun to to soften the plastic from the t-connector so i will mold to the aluminum tube. it was a easy and cheap fix, i think i spend like 7 usd. the only hard part was to get the remaining of the old plastic tube from the aluminum one to make space to fit the T-connector. its been 2 months since i did the fix and its holding well, my concern its that the rest of the plastic from the assembly will eventually break down.
@@leov30 That's awesome. Can you make a little video showing what you did?
Did something similar, lasted about a year more of the plastic did break away (didn't use JB weld) now thinking of going to a pick a part to get the assembly.
I did the same but used small peice of hose to clamp directly to bottom metal pipe
Seriously thinking about going to a mechanic this time. So tired to having to fix things on this truck. I recently had the passenger wheel off to replace a crankshaft sensor. That's just one of the many things I've done myself so far. This problem just started Sunday and I'm already down to nothing on coolant. Engine temp still reads normal for now, but smoking from coolant splattering all over the inside.
Mine blew out yesterday in the same place. When I pulled the broken piece out of the end of the hose, it just crumbled in my hand. I believe that hose is the water source for the heater so I just clamped a plug into it for a temporary fix so I could drive short distances without blowing all the coolant.
Did the temporary solution give you any issues and how long did you drive your truck like that? Did you ever replace the whole assembly?
I need to do this tomorrow and I can’t find a mechanic I am going to do it myself thank you for the video
I wish you luck with the repair. Thank you for watching!!
IAM a technician.but if one don't work on cars regally. i think that this you tube videos are great for the back yard techniction.
U are the best 👌 my friend.
Thank you so much and God bless you.
Amazing job and excellent description 👏
Thank you!!!
I had the same thing happen to my Nissan with the hose breaking off like you had. Is there any way to just replace that part that broke off without buying the kit?
Mine in my 05 Xterra broke today in the same spot. Looks like maybe it’s the same setup? I know it’s the same engine.
Thank you very much and I greatly appreciate your skill. Now my turn to make this diy repair.
Thank you and good luck. You got this!
I just finagled a repair on mine broke in the same spot. I cut just beyond every compression fitting even on the bottom metal pipe & put a Tee connected the top 2 with clamps & bottom used a small peice of hose connecting bottom to metal pipe with 2 more clamps. First initial test had no leaks Tomorrow I will top up coolant & see if I had success
Did it work?
Awesome how to video, answered all my questions!
Glad to help. Thank you for watching!
Is there a connector for this issue? Mine just broke and would like to see if there is a cheaper way to fix this.
Greetings and thanks for this post. Can this also be done on a 2009 Nissan Frontier???
I believe it’s very similar but I’m not 100% sure
is it necessary to replace the auxiliary motor? i keep finding the hose assemblies without the motor. Can i just reuse the old one?
Can you get just the plastic pieces that attach to the heater core or do you need to get the whole assembly?
That's what I'm wondering
Same
My left side tube failed but the right side looks intact. Is there a way to only replace the left side and not the right??? Also the link to the part itself is no longer in stock / available.
Just completed the repair. Thanks for the video! Now it keeps overheating, slowly. Any suggestions? I removed the bleeder valve and air shot out. Did this a few times. How much coolant should I add?
Also, hot air is not blowing in the car, but the fan kicks on.
Sounds like you still have air in the system. With the bleeder open keep adding coolant until only coolant come out no bubbles..if the bottle is over full after you done suck some out.
@@HowtoAutomotive Thank you! A whole additional gallon and were good. I'm just hoping when I cleaned out the tube from the top that none broke off and went into the line. But for now, I'm back up and running! 100% like!
jeffers77 awesome glad you got it figured out. I’m sure you’ll be OK. Thank you for watching!
@@HowtoAutomotive Where would you add the coolant? And is this while it's running?
Is there anyway to just replace that piece at 1:57 and not the entire assembly?
Was replacing my spark plugs and I barley tapped that left side hose and the damn thing broke apart
Did u ever figure that out
Where can I find the replacement part or the place to get the assembly. I can’t find the link you mentioned
Hello, nice video. I have a question. I own a 2007 Nissan Frontier crew with 79,000 original miles. Should I by pass the trans cooler lines? or add another trans cooler or replace the factory radiator to a new one. I have not yet had any issues of the mixing of the coolant with the transmission. But to be safe would would you prefer?.. Thanks.
If you're in a cold environment: swap the radiator for an upgraded one. (It also brings Trans temp up to operating temperature). If you live in a warmer climate, I would just bypass the cooler and close the trans fluid
I enjoyed the Vid ! Took out the old crap no problem. The only part I'm having issues with is getting the heater core hoses to align to the firewall heater core. Is there a easier way beside needing small hands ? One side wants to align while the other hose doesn't act like it wants to cooperate. It's like it's kittywampus. I spent almost 3 hours dicking around with it and it's getting me pretty P,O.ed Any Help with a trick to get them in line will help.
At 50 sec. What is the name of the metal pipe that the rubber hose is connected to. I need that part part number
Should i turn the rear heat on as well when refilling the coolant?
That would be a good idea reduces the risk of air being trapped
Thanks!!!!
Great video. But dealer offers the factory replacement, at $800.
Thinking of an alternative idea.
I think this is just the same with Nissan Xterra 2005 right?
But I put the hose straight thru can I continue to use the car even though I don't have the connector?
Where can I order the correct assembly for my 2010?
I'm having the same issue.
There is links for it in the description of the video. Or you could check with your local parts supplier.
What was the cost to replace it & labor
Please do a heater core for the 05-12 Frontier 4.0
Do you know how to disconnect an 08 armada thermostat housing from the water outlet and coolant pipe?
Would this be same for 2014 Nissan pathfinder
My rear heat in my Nissan Pathfinder is not working what should I do
Is that hose at 1:44 just an overflow hose??
do you have anything on changing a thermostat on a 2011 pathfinder?
Would this cause a coolant leak under the glove compartment
foreignwhipcrasher I have the same issue 😫😫
The Goat... if it is the heater core ,you have to take the whole dash apart, remove the airbags, evacuate the ac
foreignwhipcrasher I’ll just bypass the whole system I live in Miami screw it
Good video showed me a lot I have 2005 pathfinder. Thought my heater Core was bad got under the dash on top of heater box the aluminum pipes that come out of the firewall is not one piece to the heater Core it connected with a plastic clamp and a o-ring that was my leak under the dash was coming from and I had this assembly broke too I used that plastic weld putty it worked 177000 miles The air bleeder on the assembly broke first I had to add coolant and bleed the system every winter or heat would only work when the car was moving I liked this truck but after 100000 miles a lot of stupid shit crank sensor fuel pump transmission gasket oil cooler.heater assembly heater core pipe. Blower fan Electric windows valve cover spark plug leak into cylinder that gives a engine light. 2005 was not a good year for pathfinder anybody else have problems
@@anthonysorrenti3661 I have an 05 Pathfinder. I haven't had to do much work to it. I JUST changed the spark plugs after 270,000 miles on it. Everything has just been maintenance for the most part. I have changed the crank and camshaft sensors, blower motor, the engine oil cooler o-ring, valve covers/gaskets, and reengineered the heat hose assembly. I had a friend that worked at Nissan hook me up with the recall of the radiator/transmission replacement at about 100,000 miles. Other than that everything has been really cool for me. I don't race it around and I have almost always used supreme gas. ALL my fluids are fully synthetic and used Duralube for fuel treatment and engine oil treatment regularly. So far on my spark plug change, I have not noticed a difference on gas mileage. I DO have a problem with the climate control system, but I work it with the auto feature to get the fan speeds that I need. I guess that I am too cheap to spend $300 on a new unit. ESPECIALLY with 270,000 miles on the vehicle.
I am not looking forward to the problematic fuel pump replacement. I did see a video of a guy cutting the floorboard to access the pump from the top, which I thought was brilliant. I will need to figure out how I want to seal it back up before I need to perform this fix though.
Good luck with your Pathfinder!
GREAT VIDEO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
stratos175 Escape thank you!
Hey do I need to evacuate the ac refrigerant ? Let me know please I’m trying to replace this on my dads truck
foreignwhipcrasher no you don’t need to evacuate the AC. The video is step-by-step
Thank you sir!
Hello Brian, where did you get your replacement parts for this repair??
Cheryl Sanders it’s a dealer part. The part I linked in the description is a genuine Nissan parts
Is the heater hose the same for pathfinder and Frontier?
luis angel galvez yes it’s the same
This is ONLY for models with independent rear heat. The Auxiliary pump is used to move coolant to the rear heater core. Otherwise, the instructions are the same.
mine broke right where youre working on by the heatercore, do i need to get the whole assembly? or just that platic part that the hoses go into?
ss hog You’ll have to do some research to see if you can just get the plastic part. If you can Then yes you can just replaced the part if it’s available.
How to Automotive replace heater hose on a Nissan Xterra 2007
ss hog I have the same issue where plastic sleeve broke off as the video shows but I am confused why it is required to replace the whole assembly which costs close to $300. I was hoping to just replace the plastic piece where the 1" and 1/2" hose goes to..????
I am about to place an order for
Part No.: 92412-EA500 tube-water heater 👍?
So you don't recommend reusing the hoses?
Anyone know if i need to drain the coolant if all i have to do it replace my heater hose inlet connector?
Just flushed the system on my wife's 2009 Pathfinder. Then a week later that same plastic piece broke and puked all the new coolant out....
I hate Nissan.
This video guided me on the exact repair. Thank you.
Sorry your Nissan is giving you trouble. Thank you for watching !
How well does this replacement process translate to a 2015 Nissan Rogue SV?
it doesnt'
@@ray095883 I thought it might not. It appears to be a similar component; however, after I took a look a look under my hood. Have any recommendations on where to find an actual video?
Mine broke same spot... But i have a 05 xterra.. Same engine but seems like there's extra parts on this frontier 🤔
Gustavo Gonzalez they have a lot of crossover parts. That’s how they keep the cost down.
A friend had this break exactly same spot,but can't afford replacement part right now. Anyone know how to "temporarily"
bypass on this model
Too bad I found this video $280 OEM part in Amazon and $350 + tax in labor TOO LATE. GREAT video.
Thanks for sharing this awesome video.
Abstain2Obtain thank you for watching!
Perfect!
great video
Homer Hammer thank you!

Cómo cambiar el heater core de la Nissan Pathfinder 2005
what kind of knife is that @2:36?
It’s a hose cutting knife that I got from Matco tools
whats is the part number?
Nice video
Thank you. Did everything go smooth for you?
Hi Brian and all.. I have a question and hopefully someone can help. I had the heater hoses replaced at a shop, and right after that was done, the car started acting up; to be specific, the car started heating up when idling, specially when stopped in traffic. I don't know if it helps, but when that happens, the AC throws a "dusty" smell. Any ideas what might have been done wrong? I took the car back to the shop, but they said that it didn't heat up for them, I know it was either that or they cannot figure it out. Also, FYI.. I just changed the thermostat but that didn't fix the problem. Thanks in advance!
Dan Lopez sounds like there’s an air pocket in the system. This will stop coolant from flowing. The shop may need to vacuum bleed the system to get the air out.
You rock!
Thank you!
UGH Put my truck in shop for another repair and repair man leaned on this and broke. But had to have been going bad. same hose!!! Since there are no valves in this line. If you can't afford to replace the unit. Isnt it possible to unhook from the heater coil and and cut at connecting solid bar since its plastic seperating them making it 2 lines instead of 1 unit and run a heater hose clamped from heater core line to the connecting bottom line? I looked at plastic weld materials but considering temps can get to 220 in heater cores and seems plastic weld material is rated at 200, this would be the best option to cut that plastic bar and make it 2 pieces to connect a hose. WHY the hell they make these kind of parts out of plastic is rediculous! The only thing you loose is a bleeder point hence leave the radiator cap open till the air is out
Really good
Bolivar vas thank you. Did everything go smooth for you?
@@HowtoAutomotive more or less, but I did the job. Thank you for this video.
Bolivar vas Glad you got it done. Thank you for watching!
I just had this bust on me today. Of course it will happen on the hottest day of the year so far in NYC.🔥😡
SKO NYC that sucks sorry to hear that! I would be pissed to.
How to Automotive I just had to blow off some steam..pun intended..lol.. 🤣✌
SKO NYC lol don’t blame you👍🏻
Michael Seawright that sucks sorry your having car trouble. They could redesign the parts better.
My paint is falling off in the exact same locations 😂
Mine is too! I have a 2012 Pathfinder
Part number please? I’ve been looking everywhere.
92408ZL90B
Coolant tank should be replaced also
why?
I broke one of the plastic connector
I just replaced the cam shaft sensor, brushed against that same hose and out came the coolant... what a terrible design! That plastic just crumbles away
I agree they could’ve done a much better job.
always gotta make sure that you doublechecked all the clamps
Summary: find a good mechanic
