- Part 2, which includes some overlap of the first video on belts.
Tips & tricks to removing the accessory drive pulleys if they're squealing, making grinding noises, etc
Here are the options:
1. Replace the whole assembly which includes the bracket (expensive)
2. Buy an aftermarket pulley (might be the cheapest option sometimes)
3. Replace the bearings and reuse the OEM pulleys (for those who like OEM quality)

Thank you! EXCELLENT VIDEO! Mine is due and this shows everything perfectly......HUGE help! Of course, I'm not pulling my engine but when you're working in tight quarters with a vehicle you've never done it on before, this type of video is a Godsend.
Thanks Thad. This was exactly my intention with the video.
I might not be able to record the work with the limited space of the engine bay, but if someone sees how it all works they can use any preferred methods to get to the parts in the car still.
Good luck with the project Sir.
Thanks for this my idler pulley just broke so I will replace all three just as you did.
Where they all the same or different sizes? I'm trying to order them and do it myself also
Great video
+Paul Becker Thank you Paul. Glad you enjoyed it
Are the idler + power steering pulleys all the same size? I'm looking to order the pulleys only only x replace them instead of the entire assembly
Hey. I have a 07 m45. And It has a leak coming from my power steering pump. Do you think it will be ok to drive it without the power steering belt off until I fix the steering pump?
I can't certainly say yes or no due to the safety aspect.
The steering will require more effort without the belt. Try to limit how often you turn the wheels when the car is not moving. That puts a lot of stress on the system
Thank you again for your helpful videos. I plan on replacing the bearings on all three pulleys. Would you happen to have the part numbers?
Hey, check out this link where I laid out some options - forums.nicoclub.com/how-to-fix-squeaking-tensioner-pulley-t589191.html#p6763798
And thanks for the support 👍
@@EdBwoy Ed, thank you for the response. Unfortunately I didn't see it until after the job was completed. If I had read all of the comments I would have seen that you had posted that link at least two times, my apologies. Fwiw the tensioner bearings are nsk 6203 dul1 and I found timken bearings 6203 rs that fit perfectly, not sure of the quality. Now I need to address the leaking power steering pump that I discovered while working on the pulleys. It appears the shaft seal is leaking, do you have any advice? You and your videos have been sooo helpful! Thank you again!
@@marymong2651 no problem, it takes me less effort to find the link on Google and paste it here than digging through the comments.
I have posted the link as a comment and pinned it at the top to make it easier for anyone else looking.
Thanks for the great videos, super helpful! I've got an '03 FX45 that has a broken idler pulley. I've started pull things apart to get to it, but my engine has the large, white plastic cooling fan mounted in front of it. I haven't been able to find any information yet on removing that to access the idler pulley. Any suggestions? Thanks again!
I would assume the clearance behind the fan would still allow you to get some tools into the area to access the idler pulley fasteners without requiring fan removal. Is it too tight?
Anyway, with very limited exposure to FXs I am not certain, but I would hazard a guess that the clutch is bolted to the water pump pulley by studs and 10 or 12 mm nuts and when you separate them you can wiggle the fan+clutch out.
However, you can check this link for the exact instructions for this job and more from the factory service manual. www.nicoclub.com/infiniti-service-manuals
Thank you for the reply sir! Yeah, there was enough room to change the belt for instance, but not enough to get at the idler pulley. I think you’re correct in the removal of the entire fan unit, though I kept tinkering and was able to remove the fan blade by feel(couldn’t see the bolts) and left the clutch assembly on the pump. This worked out anyway as I need to replace the fan blade too. The blade off allowed me enough access to the pulley too. Thanks again for these vids man, being able to see the engine out of the bay made it way easier to work on it in cramped quarters! I’ve just recently started working on my cars, trying to fix things myself and vids like yours really help give me the confidence to dig in!
@@guymcclung man, I am very happy to hear you got it done, and especially seeing this statement. *...being able to see the engine out of the bay made it way easier to work on it in cramped quarters...*
That exactly was my intention with these videos. Sometimes I would get comments ridiculing the format of video but I was thinking, if I stuck a camera in the engine bay I wouldn't be able to show that much detail..if at all. However, if I show you where everything goes in broad daylight, then you'll be able to work on it in those poor visibility areas, whether you choose to attack it from the top, bottom or sideways.
@@guymcclung best of luck with the repair, and I hope you get a long enjoyable ownership experience with the FX45.
And not sure what your sources for parts are, here's something that might help - forums.nicoclub.com/how-to-fix-squeaking-tensioner-pulley-t589191.html#p6763798
@@EdBwoy Absolutely, I 100% agree! Hoping to get some more life, though she's at about 225,000 miles, but we'll see. I think my bigger concern are all the materials, plastics, interior, etc that seem to be disintegrating around the engine before it stops running, lol. Thanks again for all the info, guidance, and parts tips.
Idk if you will comment but do you know where i can get a idler pully on a 2005 infiniti q45?
I always reply if I see the comment and have time.
If you are looking for a new one, the Infiniti dealer has them. But you can just replace worn bearings.

Great video really helped me out a lot changing out all my pulleys on my 07 M45. I have a question for you, when replacing the pulleys. Are you supposed to reuse the metal plate the bolt goes through on the new pulleys? I tried using it with all the new pulleys I purchased and the pulley won’t spin at all when you tighten the bolt down but it will spin freely without the metal plate. I’m getting another weird noise coming from the engine bay at this point.I’ve replaced both tensioner pulleys and the idler pulley. I’ve also replaced both of my belts as well. I don’t know what that noise could be any idea??
Thanks Ivar, I am glad you were able to benefit from the video.
On the metal plate, yes you should transfer it onto the new pulleys. New pulleys are harder to spin by hand, but it should not be that much harder with or without the metal plate. Just make sure you have it in the right orientation, so the contact surface is the same whether using just the bolt or the plate.
Where did you source your new pulleys? Did they look similar to the ones you took out?
On the other noise - is it new and noticeably louder? Does it change in volume when the AC button is pushed? Does it change when you turn your steering wheel?
Wow thanks for the fast response can’t tell you again how much this helped cause I know the dealer would have charged 380-400 dollars and this video made it so simple. I got the two tensioner pulleys from Napa part number 38005 and 38011. I purchased the idler from Auto Zone part number 231150. They are kinda similar but they don’t look exactly like the oem ones that were on the car. I’m going to pull them off and see if the bearings are the same size in the new ones hammer the new ones out and put them on the old pulleys and see if it makes a difference. The noise is like something is shaking or rattling. It wasn’t making the noise before I changed the pulleys so I figured it has to be from one of those areas.
Gotcha. Those are the same numbers I've found to work online. The bearings should be the same.
Caution, pressing is better than hammering as you could damage the new bearings with that impact. Whatever you do (and especially so if you have no other option but to hammer), make sure you are putting pressure on the outer race - that metal ring that is in contact with the actual pulley.
I have so many spare pulleys, I should probably start an exchange program.
forums.nicoclub.com/post6763798.html#p6692126
And the noise troubleshooting makes sense. They make weird sounds when out - scratching, screeching, popping etc. You might be able to isolate which system is noisy by using an automotive stethoscope or the old school solid piece of metal on a non-moving part, of course. I would put a long metal rod onto the bolt/nut of the pulley and a good one sounds like a fast stream of water while a bad one sounds like mini-explosions in my ear.
These are just options to save you time.
EdBwoy Cool thanks again for your help 👍
I just want to say thank you so much you have no idea I know many people will look at this video is being long and I say useless absolutely not this save my ass I'm changing the idler pulley today that's damn hot out. Thank you!!!!
You're welcome Jake, glad to help. Hope you were able to get back on the road quickly
@@EdBwoy I just stripped the belt tensioner pulley bolt, oooops counterclockwise tighten...
@@top6ear bummer! Have you found a replacement bolt/tensioner yet?
Do you happen to have all the part numbers you used for the pulley bearings?

@@EdBwoy thanks!! great video. thanks for creating this.
Any idea on the torque specs for those 12mm and 14mm bolts for the idler?
Not sure, on those I go by feel on those.
You can get the specs in the service manual. nicoclub.com/infiniti-service-manuals
@@EdBwoy knocked it out yesterday. .did the same..man it was a pain getting those done without removing anything out of the way..lol
@@EdBwoy any videos on the valve cover gaskets? I'll be doing those either today or tomorrow. . Got the gaskets and pcv o rings ready to go.
@@LShocker94 glad you got it handled. Is yours an 03/04? The hydraulic hoses add an extra level of fun.
No video on full valve cover job, but I do briefly discuss it for my 06

You need to take the engine out for the belts?
No, you dont.
i have recently taken apart my radiator for replacement. what is the connection between the oil filter and under the oil pump connection called. it is the lowest connection on the drivers front of the engine
its showed clearly at 5:28
next to the tensioner under the oil pump connection
@@johnpangelina8219 the electrical connector? That's the oil pressure sensor
@@EdBwoy yes under the oil pressure sensor
@@johnpangelina8219 looks like a blank from casting. Like the oil pan should be able to accept an accessory like a cooler.
However, I've never seen anything attached there in all the VK45DEs I've come across
Is there a way I can give u a call ?
What's the part number for the idler???

If you get a chance to buy the Canadian made pulley the machining on it is incredible it looks like a far better product.
I have a q45
I thought VK45DE had timing chains?
They do. This is just the accessory system. Most cars use belts for them, but the timing chain/ belt is connected to the crankshaft and camshafts.
In this video, the timing chains are hidden behind the timing cover.

EdBwoy thank you bro I'm learning:) so are these engine headaches? As far working on them? Also I have pulley issues but the last owner replaced the belts not sure which think he said drive belts? It's making a whinnying sound when idling I'm guess idler pulley are valve cover gasket replacement a pain to do on the VK45DE? Thanks ahead
Not a problem man, I wasn't born knowing these things either.
The engines aren't too bad to work on, for the regular stuff (pulleys and belts). The valve cover gaskets and spark plugs will be a little bit of a pain due to the engine bay being so cramped.
Other than that, you'll rarely have to open your hood for more than oil checks. *very important* .You have to check your oil often
EdBwoy thanks again man, yeah I have yet to remove my engine cover that alone seems like a headache lol I heard to get underneath the engine it has like 17 screws on the engine undercarriage cover?
