2 days ago I took my car for an oil change, and Infiniti wanted to charge me $795 to replace the 2 heater hose plus another one on the other side of the rear of engine with the connector and all clamps, calling it preventive maintenance. I said all the hoses look great, why would I spend that much money when all the car needs is 1 connector and 2 clamps? I will be doing the exact thing in the video myself.
hey bro thank you so much for the video just have a confusion with the parts because in their website they have two different hose sets which gets confusing
Thanks for your video...I'm looking to do the heater hose coupling replacement as I can see signs of coolant leaking. If I were to do this, how much coolant will I lose from the heater hose area and should I have a drain pan underneath?
You lose a decent amount. It will most likely need to be rebleed as air will be introduced to system. Pan would help to catch the old coolant. But I would plan to new and rebleed the system
@@CRTFD_G thanks! I do plan on bleeding the system once replaced. Would you suggest draining some from the radiator plug? I'm assuming it's going to be messy otherwise if I just start at the heater hose without draining some first?
@@spaxe7 depending on your millage doing full coolant flush isn’t a bad idea. You can drain it all fairly easy from bottom of radiator to avoid the whole mess
I hate the stock clamps where you have to squeeze it together. You’ll need long needle noose and slide it down the hose as your squeezing it. Replace them with hose clamps
I would never listen to mechanics about pressure washing your engine cause what the F do they know? Just keep doing what your doing the way you want to and rock out bro.
Thanks for sharing 🙏🏾🙏🏾 I’ve been planning to do this for a long time… Mine is ‘14 Q. Is it the same process of burping if I will only change the plastic port at the back? Thanks! 🙏🏾🙏🏾
Bro appreciate you so much. Your channel saved me alot of headaches and money. Question if I replaced the heater hose in the back of the engine do I need to burp my system?
Yep. If you introduce air in the system. Needs to be all liquid, no bubbles, and filled up to the brim of the cap and at max in the reservoir. Just did my heater hoses and the z1 bleeder 2 weeks ago. Total pain but worth it.
Is there any way you could make a video of hot to drain and replace coolant on 3.7L Q. I happened to have 2016 QX50 AWD (same engine) and while i have no problem doing brakes, tranny fluid, differential fluid and the rest. The only thing that scares me is replacing coolant on this engine and at the same time cant see to find any complex of how to? Im no mechanic just garage warrior lol.
Hey man. If you can drain your trans/diff fluid, a coolant flush will be walk in the park. There is a screw at the bottom of the radiator to drain it all or you can just remove the lower hose from radiator on driver side.
Does your car overheat while being stuck in traffic with the A/C on!? Mines for some reason does and once i turn off the A/C it goes back to normal temperature! Its 2015 Q50 as well! I live in Arizona as well
@@CRTFD_G I’m trying to figure why it does that!! Took to the dealership in Mesa told me they had no idea why it overheats! Took my money and couldn’t find the issue!
I need to do this exact same thing on my 2015 Q50. The metal connector you have "Dorman 56430", on their website it says STEEL material. Is it coated or galvanized steel? Will there be any rust problems? Also, are the hose OD and ID diameters exactly the same as the OEM plastic connector (especially the outside diameter)? For the air bleeding in your coolant flush, placing a funnel where the radiator cap goes and idling the car and also revving at 2000 RPM, is that how you bleed out all the air? If so, about how long should you be doing the funnel bleeding?
what size/type line did you run into the z1 bleeder for your turbo coolant lines on the G37? i recently got a comp turbo to swap out for the precision on my bp kit so im trying to source the right water lines/fittings
Infiniti tried to charge me $750 for the rear heater hose fitting 🙂 ordering mine and doing it myself 😂🙏🏼 literally saved my life ! Appreciate you
Just went in today. They tried charging me $750 as well. $769.04 to be exact. 😂 Def taking it to my uncle. May you have a smooth repair.

Same here today. I just needed the metal coupler ($10) and a flexible tip hose clamp pliers ($40). $50 vs $752.46
Same smh
Same here
Should I burp my coolant if I only change my heater hose connector?
That hose is notorious for snapping in half, just bypassed it and thew a metal pipe and clamps, sent it😂

How bad was the coolant spill when you unplugged the heater hose fitting
Decent amount. Will need to add more coolant and most likely bleed the system. I
Hey was just wondering how you got the clamps on the heater hose off I’ve been trying for and hour and still can’t get them
I hate the stock clamps where you have to squeeze it together. You’ll need long needle noose and slide it down the hose as your squeezing it. Replace them with hose clamps
Thanks dealership wanted $600 to fix just ordered my dorman 56430 going to put on my self $9
Wow $600 is theft. Glad I could help - Cheers
900$ for mind 😂 shit i regret to buy Q50
Nice vid man, I’m thinking of upgrading the hoses as well
My reservoir keeps losing coolant would this be the fix?
Grab your hoses and squeeze for any leaks
Yeo bro, I know this is old but do you have aftermarket covers for the bottom parts of the car or stock? If so do you know maybe where I can get them?
You mentioned you have a ecutek module, could I get one for my q50 3.7, if yes where?
Sure. You just need ecutek Bluetooth module
Right now they charging me $325 to do that job please what’s the size of the fitting ?
I would never listen to mechanics about pressure washing your engine cause what the F do they know? Just keep doing what your doing the way you want to and rock out bro.
How much coolant is needed to flush the system?
@@Saqib-l2e get 2 jugs of the OEM blue coolant from Nissan/infiniti dealer
@@CRTFD_G Can I flush the system on jack stands or does the car need to be on level?
Are you able to change your dashboard lights? I see yours is blueish purple around rhe speedometer and mines is white
I have a 2015 model. I’d imagine yours is newer maybe?
@@CRTFD_G mine is 2018 Q50 Red Sport but sworn I seen one or two 2018 with the same speedometer lights
I got a 2021 Q50 rental right now & the cluster is white like your saying. Cluster & steering wheel changed in 2018
How are these hoses holding up?
Hi I dont see the link for the new heater hose can you please attach, Thank you so much!
Google: Dorman 56430
@@CRTFD_G Thank you so much just ordered & the hoses too!
The gold part goes into it as well ?
I guess all Q50 has the heater hose issue, I’m going through the same issue.
Q70 too 😭
All 3.7 engines have this issue
@@CRTFD_G 🤦🏽♂️ thanks for the video fixing mines today
SAMEEEEE
Update: I was able to fix thanks soo much !
Bro all this time I thought I had an bad head gasket and it comes out that my coolant was leaking thru the heater hose 😅
I’m saying 😮 had me worried
What size hose clamps do I need for heater hose?!
@@Saqib-l2e I think it’s 5/8”
I don't think thats the right size. You sure?!
If fitting in the back on heater core hose holding up good ?
Yes sir!
@@CRTFD_G appreciate it doing it today on q50 if I’m just changing the bypass tube is there need to purge the cooling system
Not sure what a bypass tube is. But if you introduce air to system you will need to bleed it
Thanks for sharing 🙏🏾🙏🏾 I’ve been planning to do this for a long time… Mine is ‘14 Q. Is it the same process of burping if I will only change the plastic port at the back? Thanks! 🙏🏾🙏🏾
Yes if you air enters coolant system in the back you will need to burp it

Hello did you have to drain out the coolant to replace the the rear coupler dorman ?
It’s a good time to replace with all new coolant. Otherwise you will just lose a lot when u undo the stock plastic fitting

All these people saying these crazy prices my mechanic charged me 330 for this fix not the best but to keep my hands clean why not
What size is the heater hose connector?
3/4”
what size/type line did you run into the z1 bleeder for your turbo coolant lines on the G37? i recently got a comp turbo to swap out for the precision on my bp kit so im trying to source the right water lines/fittings
To be honest bro I’m not sure I upgraded to an air cooled comp
