The power steering pump failed on this 2013 G37x. Symptoms included increased noise from the pump, loss of assisted steering, and power steering fluid spraying all over the engine bay was a dead giveaway.
We had to drop the radiator fan assembly a couple of inches in order to remove one of the power steering pump bolts. Everything else was straight forward.
Cap on the power steering reservoir calls for Dexron ATF fluid so we used Valvoline Full Synthetic ATF which meets Dexron VI specs.
Best video on replacing this part on TH-cam 👍🏼
IMPORTANT TIP: loosen the 2 10mm radiator fan bolts on top and wiggle it lower to get the 14mm bolt out.
Dude, did you even watch the video? What are you talking about? He already said that.
Im gonna attempt this tomorrow in my kids 2010 I have been sweating this job since there is no room to even see the pump i thought I had to take the front end off . Thanks for this video I think you saved me allot of grief.
I thought the same how many hours did it take you still don't look to bad
@@abner0404 remove the pass side intake, remove the belt and lower the fans down and take the two bolts and pressure sensor switch off. i'd say an hour if you're drinking a beer in-between.
Great job! No unnecessary commentary and nothing but the facts. Keep it up! 👍
Thanks for the video very helpful was able to replace my power steering pump in a couple of hours!
Well done, straight to the point and no bothersome fluff 👍
Just finished doing this using your video. Took me 3 hours. Everything you did was right. Just one thing, it looks like your pump was easy to just wiggle out. Mine was stuck. But i just used a long pry bar and put it between the pump and the engine and it popped right out
Saying bolt sizes would be highly appreciated; I contemplated killing myself not knowing the 2nd bolt was a 14.
Same bruh I been trying to get that fucking bolt out for 2 hours now
I was about to burn the car down!
Really helped! Thank you for creating it! I tried it today. But my issue that I have the wrong part. The years above 2010 maybe the same - mine has the diamond shape low pressure house inlet. And the hp is mounted sideways not on top. The banjo bolt sideways.
Great video I’m going to buy one of those torque digital tool I got there
100% 10/10 fucking great video excellent explanations of what needs to be done to make the job easier this is how you make a DIY video you just got ur self a new sub
👏 great video and instruction. What did you torque your banjo bolt to? Thanks again
Excellent video man! Great job Thank you for posting. I'm gonna have to do this job on my mother in laws car smh :)
Nice vid! Although I hate working on these effn infinitys, there’s absolutely zero room to get to anything without taking something else apart.
Great video, straight to the point!
Hey man my power steering is leaking from the hoes you loosened at 2:25 , is it possible it just needs to be tightened with new orings or sum? Should I just replace the whole pump?
What was the point of removing the mass airflow sensors from the intake when you could have simply unplugged them?
Lol no point really, just happened. Would have been easier to unplug them.
@happywrenching I loved the way you answered this honestly with type of animosity
LOL
What was the torque spec uou used on those two bolts to put the bracket back on the pump?
How you removed the wire harnes clips? I’m struggling with those
Has the power steering fluid given you any problems. Dont know which one to buy? Ive heard between Dextron III and Dextron VI
Where did you buy your pump?
What symptoms where you getting before you changed it?
how did your pump and bolt go in so easy for the reinstallation 😭 been on this for hours
Are hitachi bad power steering product or no bc I always see people replace that one all the time
Hello. I'm thinking about buying a G37, but on the Carfax, it says that the power steering pump was replaced on 4/17/21 at Tire Discounters, however, it says that the power steering pump was replaced at that same Tire Discounters on 2/26/21. It also says they performed an alignment on 4/17/21, however, they also performed an alignment on 12/4/20. Do you think I should pass on this car?
I know this reply is probably far too late, but the main cause for power steering pumps to go out in the AWD G37s is trying to drift and things like that. They have so much weight in the front that swinging it tends to just destroy the pumps. So it’s possible the owner before was just an avid hoonigan. Car was probably driven very hard and I’d probably stay away from it. However these cars are extremely reliable and can handle abuse well.
@@jonnystange4017 you clearly no nothing about what you are talking about... its not the weight that destroys the pump its the fact its being starved for fluid when swinging side to side like water in a cup. on top of that its IMPOSSIBLE to drift and awd G unless you're in the snow. speaking from experience as an owner, of course.
@@HenDawg.206 I used to be an owner as well and I hate to admit that it is actually rather easy to swing them. And maybe it’s not the weight, but it makes sense because it doesn’t seem to be as big of a problem in the RWD sedans and the only real difference is the AWD weight.
@@HenDawg.206plot twist, it’s not impossible to drift an awd Infiniti unless you’re in snow. There’s a fuse you can remove that makes it RWD
Hi bro how do I know if I need a 4 wheel steering pump or 2 wheel
Go underneath the car and check for a device connected to ur differential. 4ws is basically the ability of ur back wheels to turn slightly with the front
Good job guys thanks for sharing 👍🏻.
What were the torque specs for the pump? I may be doing this job for a friend... Please get back to me. Thank you!
How much was the part ? Also does it fit in a sedan 2012 ?
Very helpful!!
Awesome video!!!
Why did you unscrew the maf sensor instead of just in plugging it?
I think someone else pointed that out too, just a derp moment I guess.
@@happywrenching ah okay okay
Does anyone know whats the name of the tube coming out of the pump is called , had a guy replace my power steering pump on my g35 and he told me it’s missing the part and he could take it off the old pump but it was already returned for the core deposit
I have a 2009 Infiniti G37x and I need to replace both the high pressure and low pressure steering lines. What is required to remove in order to snake those lines through? The engine looks very similar to what you have. Right now it looks like the outdrive is the major piece in the way that is preventing me from getting the lines out from the bottom. Is there a trick to this?
Hey did you ever find a solution and get this fixed?
@@DanielB-d3v During the process of replacing the lines it turned out my steering rack was leaking, it needed to be replaced and I ultimately had to have a mechanic do it. The car was operational but it just became one problem after another, my rear subframe was so rusted, it broke and the rear end was shifting all over. The cost to fix it was way more than the value of the car, ended up trading it in for a lesser car just to have something running. I miss the engine of the Infiniti, too bad the car fell apart around it, good ol' Midwest salt.
@@NotUpTillNoonGaming awh damn man , I’m sorry that happened . I hate to hear about the rust , those bastards. 😞 hope you can one day recoup what was lost into a different build.
@@NotUpTillNoonGaming recommend any psf ?
@@DanielB-d3v I don't think I used anything fancy, just what I could get locally at an Autozone or O'Reilly's. I used to get fancy stuff until it was a pain trying to find stuff locally vs only online. It might have been Prestone or Valvoline.
So let me explain what’s going on with my power steering.
The steering is never hard to turn and the reservoir is never low. I have a 2015 Infiniti Q70L that requires an ATF fluid. My power steering pump randomly makes noise at idle. The ATF fluid is clean and is replaced every 50,000 miles. Currently my Infiniti has 156,000 miles. I performed a vacuum test at 20 pounds of mercury and it passed the test for five minutes. Even though it’s been vacuum tested is there anyway an air pocket could be present in the system? Or is my power steering pump simply need to be replaced? Thankfully I can purchase a brand new Hitachi Power steering pump which happens to be the OEM provider for a reasonable price.
Keep in mind I am a rideshare driver that is on the road constantly picking up passengers.
I'd say your pump needs to be replaced.
Was it making a squeeling sound when you would step on gas? In my 370 at idle when I stop sometimes it loses voltage. I replaced alternator; tensioner and idler pulleys. I'm so mad bc Now I'm pretty sure it's the power steering pump
@@joseC2013did you ever find the solution?
Help a lot! Thanks
Everything can be done with the car on the ground?
You'll have an easier time moving the radiator fan assembly out of the way if you have access from the bottom. We had the car on ramps during the job.
Had a whine at first ,was able to turn wheel so then I replaced power steering once I did whine was gone but was unable to turn wheel ?did I do anything wrong?
Air in the lines
i just changed the power steering for g37x now it’s throwing smoke and check engine light is on idk what’s going on
Lol
What was it? Why was it smoking?
Its probably your alternator that caught some leakage from the pump and blew it
Hi what noise or problem that lead to the replacement of the power steering pump remplacement ?
It was pretty easy to diagnose - no power steering, had the classic power steering pump whine noise, and best of all, power steering fluid being sprayed all over the engine bay.
@@happywrenching
Thank you.
@@happywrenching what about smoking near the power steering pump?
How did you put the Belt back on
Will this work for a 2017 370z
What is that tube o ring called i need it
WHERE DID YOU BUY THE REPLACEMENT PUMP PLEASE HELP
Not sure if it’s still relevant to you but it’s a dealer only part. I bought one thru my shop for my 370z but apparently the part itself is like 1200
Rock auto. I found an OEM one
@@JackRyanMeanswhat is the name of that brand
@@Artsorb Hitachi. Hope this helps
@@JackRyanMeans thank you 🙏🏽
I think my steering pump on the Z went out just like that .the wheel is just harder to turn all of a sudden..this is a fucking job damn it .gonna have to wait a while for this to be fixed..fuck me
Careful not to torque the bottom bolt to much or you’ll crack the bracket like I did lol
Bro! Me and my friend just did this and I’m up looking for answers lol. Did you end up replacing the bracket yourself? And how crazy of a job was it if you did?
You ever replace? Gonna replace my Power steering pump and lines aswell.
it is necessary to move the fan
why?
howd you put the timing belt back on
That's the serpentine belt.... I should have filmed it but if you google "g37 serpentine belt diagram" you can see how the belt goes back on.
Think I bought the wrong pump on ebay.
I watched a video where the dude said if you get a pump out of a RWD g and try to put it into a AWD g the pulley wont line up and will not stick out far enough just got done with it and the PS pulley isn't lining up with my alternator pulley. i'm beyond pissed right now, the guy on ebay said it shouldn't matter if its AWD or RWD but it does >.> hopefully he gives me a refund.
Did you get a refund
Part num on the replacement?
You took the bottom cover off and never touched anything on the bottom of the car😂
Is it the same for a 370z?
Yee
Unplug the maf sensor
Infiniti wants me to pay 1700 for just the pump
Get one from rock auto go to a local shop have them install it
You probably wont spend more then 600$ total
PartsGeek Official Hitachi PSP $220
Local dealership here charges me 1500 something for pump, new belt, and flush power steering.
Too much work and wayyy to long I will upload a 15-20 min proper change with royal purple fruit on my page tomorrow
Where the video at
