Fantastic instructional video. I just had this exact same problem with the connector rotting out. Thank you very much for producing this video and saving me a lot of money and time.

thank you for this detailed video, one of the best videos ive seen on this issue and stright to the point and nice close up camera of the work being done , gonna tackle this issue in 2 days when my parts arrive, i have the z1 bleeder port and upgraded silcone hose coming
Yup mined is a 2008 ex35 (vq35hr)and sure enough the connector peice one day while heat was on sent a puff of smoke from right side up under my hood, did it twice then went away as i was in motion, turned heat off immediately, long story short 2 weeks later due to leak always drying before i can find it, parked it on a hill turned heat on and BAM leaking at connector, baught extra hoses and things but literally only connector peice literally snapped in half and was brittle and broke apart as i was taking it apart..... took a good hour to 2 to do so cause i shouldve purchased long needle nose pliers.....but yea problem fixed!
When I was getting the old rusty plastic out it snapped I got all the pieace out but I think I dropped few little pieces inside, idk what to do I put everything back on a new one and my car was still overheating
good video to learn from bro thanks. i have a little problem with my 2014 370z and i need answers fr, i changed the coolant fluid and the heater hose connecter but afterwards while driving the car i noticed water sound sloshing behind the steering wheel! i am kinda worried tbh and hope u got any idea to figure out what caused that issue and how to solve it. thanks again
Check your coolant level , if it the fluid keeps going down then it’s a leak in the coolant system, but since you mentioned the steering wheel maybe it could be power steering fluid making the noise , is the noise when your moving the steering wheel?
@@Gm29_mtz i’ll keep an eye on the coolant level since i don’t use the z as a daily car but about the sloshing sound it only happens when i fully stop and then accelerate and very rare when i take turns
How hard was it to get the hose off that goes back into the engine? I replaced the coupler piece and realized the hose that goes into the engine is now leaking
I used 2 oem hoses and adapter , but u can just buy 1 long hose from oreily, take your old hose ,show it ,and they’ll give u the length u need , u Just need to cut in half in order to put the adapter in between and for the adapter I recommend u buy the aluminum kind , so it will last forever
Use pliers to wobble them out , since they prolly never been taken out they are stuck, last option is to cut them off and make sure you clean the residue good
Hey gotta question bro I gotta g25 with the same issue I couldn’t find the rite hose but I got just this one hose that actually fits perfect is it best to use both tho ?

Hey guys you can get the metal one from advanced auto parts here's the part#84741, it's the 3/4 fitting it's around $5, I hope this helps

I alwys just refer to them as a coolant/heater hose
That hose is plugging into your heater core for your climate.
Thanks man a very simple straightforward video. No bs. Appreciate you taking the time to make it
I am having exactly the same issue on my QX50 just ordered the aluminuim replacment. Great Video Thanks.
No problem
This was a valuable video for replacing this heater hose. Thank you! However, I would not use oil as a lubricant to put on the new hose. Use dish soap (Dawn) instead. Thanks again!
No problem and appreciate the tip 🔥

Good looks brother! Same shit happened to me recently and this video helped out a lot
No problem bro
When I was getting the old rusty plastic out it snapped I got all the pieace out but I think I dropped few little pieces inside, idk what to do I put everything back on a new one and my car was still overheating
Check your thermostat
I have the the same problem with my 2011 z . Just bought the heater hose set from Z1
Nice I just bought it too in blue , Black Friday sale
good video to learn from bro thanks.

@Cloudzix1 you got air in your coolant. Gotta bleed/burp the system
How hard was it to get the hose off that goes back into the engine? I replaced the coupler piece and realized the hose that goes into the engine is now leaking
Nothing hard , just takes time , and the right pliers
Bro I been trying for 2 days to take that shit off
Good luck trying to putting the clamp on the right spot
And are familiar with the passenger floor getting wet when it rains??
That problem has to do with your sun roof hose being clogged , they have videos on TH-cam on how to unclog the sunroof hose
This part right here is probably clogged up

You can either clean it out , or order that part , it’s better to try and clean it yourself to save money and get the problem out the way
Hey man dealing with the same problem did you end up figuring out what to do?
You use 1 hose when u replace or you used the 2 hose & adapter
I used 2 oem hoses and adapter , but u can just buy 1 long hose from oreily, take your old hose ,show it ,and they’ll give u the length u need , u Just need to cut in half in order to put the adapter in between and for the adapter I recommend u buy the aluminum kind , so it will last forever
Did you drain the coolant before replacing?
I didn’t , but from what I’ve seen most people do
Had the same problem mines were split and I paid 200 to fix
I can’t take off neither the heater core hose and the hose that goes in to the water bypass
Use pliers to wobble them out , since they prolly never been taken out they are stuck, last option is to cut them off and make sure you clean the residue good
do you have to bleed the system or burp it ?
Yea , there will be less fluids spilling when disconnecting the hoses
@@Gm29_mtz so i have to fill it and bleed it ?
@@big_guy-wi1bf make sure u buy coolant first , bleed then refill
so after connecting the new part bleed and refill ?
@@Gm29_mtz my problem is the plastic connector piece is slowly leaking
Just order the aluminum 1..do I have to use the plastic 1??
Sorry for late reply , no you don’t need the plastic , the aluminum replaces the cheap plastic one that Nissan provides
Did u bleed the system after u installed it ???
Yupp
yo bro was that bypass causing overheating bc that’s the same setup on mine and i’ve been thinking about putting the 3 part hose back on
Mine wasn’t overheating , but check for any leaks around the area and inspect the hose for deterioration
You don’t even have to remove all that
Thank you.
Y’all know if it’s the inlet or outlet hose
It’s gonna be both ,inlet and outlet hose , it’s a 3 piece system with the connector in the middle , just make sure you get passenger side hose
Hey gotta question bro I gotta g25 with the same issue I couldn’t find the rite hose but I got just this one hose that actually fits perfect is it best to use both tho ?
You might as well replace both , bec if you decided to change another time , then you have to do the process again
And if it’s a hose that is heat resistant than it should be fine , as long as you clamp it down tight
@@Gm29_mtz appreciate you my guy I ended change the entire hose now my car back A1💪🏽
