Thanks for your videos. Just wanted to point out that Infiniti does state 30K for replacing the S belt but that seems a bit overkill. I own a G37 coupe and the belt is still in good condition at over 60K. Most guys on the G forums don't replace the belts until after 50K with no complaints of premature belt failure. You didn't mention that the tensioner has 3 notches on top that show where the belt tension should be. If the tension falls out of the range of the 3 notches, you should replace the tensioner. It is also a good idea to inspect the pulleys and replace them especially if you have noise at start up or shut down. Keep up the good work.
Thanks a lot for your input! Yes, I also think 30k is overkill. I usually do belts around 50k but mine was making some noises. Luckily, all pulleys seem fine and the noise is gone now. Thanks for your added pointers, very useful. I try to include as much as I can in the videos but inevitably, something always gets left out.
Wow, thank god. I went to a Infiniti dealership, and told me I needed to replace my drive belt. Cost $349!!! Guess now I have some time before I can get it replaced.
Just replaced belt (possibly original) on my 08 m6 g37s coupe with 105k (I bought it about 7k miles ago). 1/2" ratchet hole. Tried to change mine from above, like you showed. Finally got frustrated enough that I dropped the plastic "splash panel" underneath (ten 10mm bolts, removed with cordless drill), and it was a ten minute job from there. Much easier. Front of car was already up on ramps after oil change. Alex: thank you so much for taking the time to make these g37 videos. VERY appreciated and well-done.
Thanks for the great video, sir! The Infiniti Stealership wanted $220 for this job on my 2009 G37x sedan (106k miles). I bought my baby gently used in 2013. I don't believe the belt had ever been replaced, but it didn't look as bad as they claimed (stretched with cracks forming)... The wifey and I took 2-ish hours. She completed the majority with her baby hands working magic from above while I fed and pulled the belt from below. We didn't jack the car up or remove the bottom panel. Time-consumers: finding a ratchet that fit the square hole, finding a curtain rod to place on the ratchet for leverage, and looping the belt perfectly over each and every pulley. My ride started up perfectly, and our marriage is still in tact. GREAT SUCCESS!!!
Lol fuck infiniti goto a nissan dealer they can do anything infiniti can. 110.00 for the belt change still alot just for a belt but way cheaper then 220.00
What a pain!!!! "Wrestling the belt a little" is a major understatement! It REALLY helps to remove those two idler pulleys is crucial. The next problem is getting the belt around the tensioner pulley. It took me about an hour to change the belt out.
Thanks for the video! 2012 G37 Journey Sedan w 86K. I'm a novice so I tried to get around removing pulley mentioned, 45 min later I wish I had. It makes a huge difference in accessibility to the rear-facing pulley and routing the rest of the belt. Saved me $220 at the dealership!
I just replaced my belt on my g37 at 85,152 miles on the original belt. Your not kidding it’s a challenge to get the belt around the pulleys. I removed both air intake boxes for better excess to get the belt on so I would have to mess with removing the pull that you moved. Sure it took a little bit of 15 minutes to take off and put on the air boxes, but it save me from fighting to put the belt on and trying to make sure the belt wasn’t moving all over the place or off the pulleys . Other than that I had a good time with my G37 do maintenance oh her. 😘😘😘
Best vid on youtube for changing the belt on this vehicle. Just got a 2012 and changed the belt today. I would add that if you open the oil filter flap under the car so you can see from the bottom made taking off/ putting on the belt 10 times easier.
Wonderful video! This is the first time that I have changed the serpentine belt on any car. My G37 already had 117K miles, so I figured it was overdue. Interestingly, the belt looked fine, i.e., no cracks at all and no squeals, probably since it was parked in a garage most of the time and driven primarily in relatively mild Southern California. I carefully studied your video, screen captured the belt and pulley diagram, took pictures of my engine compartment, and went at it. It took a few hours for me to changed out the belt, mainly due to the initial difficulty in placing the 3/8" wrench into the tensioner; and since I decided that it would be a lot easier to remove two of the small central pulley units in order to easily place in the new belt. I did notice that there was an extra pulley on my car than depicted in the manufacturer diagram, but overall the belt looping was not really different. Anyway, thank you very much! You are the Man! (Your video about changing spark plugs on the G37 was awesome, too!... I changed those out about a year ago.)
I just did mine last night. I realized it will save u a lot of time if you just unbolt the tensioner. Tryn to route the belt behind the tensioner pulley is difficult because of limited space. I was fussin with my belt for an hour last night trying to get the belt in the proper routing. Once i decided to remove that dam tensioner it was done in 15minutes. But your video is a good guide on removing and installing thank you
Thank you for this!! I literally was going to shop around for a shop to go have it replaced cause I thought it was going to be difficult. That neat trick with the tension pulley boosted my confidence on being able to do it. Lol
I stopped the video at the diagram and went out to change my belt. I knew it was going to be tough getting it back on because it was a pain to get it off. After fooling around for 10 minutes I thought to myself, "there's probably a trick to this." Rather than check the video I removed the bottom plastic engine cover to get the dang thing on. It would have been so much easier to remove that pulley... By the way, the original belt lasted 13 years!!! And thanks for posting this.
Replaced recently at 75K, noticed prior replacing, that tensioner mark was at "replace it position". Not sure if the belt was replaced earlier. Disconnecting the radiator hose also helps to reach the belt. Belt condition was ok, except, almost whole length, was split. Checked pulleys, foud that possibly a small piece of rock somehow fell in the pulley groove and rubbed through belt groove. Removing pulley #4 helps a lot also.
Get that old belt out of your trash and put it in your trunk, As your knew belt can and sometimes will break, during its "stretch"-"break in period" not only that...if by chance it breaks at anytime...now you have a back up...thanks for the video, and like always you do a very nice job.
I have a 2010 G37x with 171K miles, not sure if the serpentine belt changed anytime. Recently I found a squeaky noise and ordered a belt from amazon. I felt opening the filter change cover underneath ( no need to remove the entire cover) and removing the coolant reservoir is good enough to the change the belt easily. Bit tricky to push the belt inside the tensioner, once that is done from the underneath, I could work from both top and underneath to place the belt properly. Your video was helpful, especially the diagram. Thank you.
Thanks for the video, appreciate you showing us how to get this done! Infiniti just quoted me like $250 and for about $65 I can get the OEM part and then tackle this myself and use my savings for some new Michelin’s PS4S! Thanks again!
Just replaced this today because my belt ripped off while I was on the highway and this video really helped thanks a lot ! I struggled so much with installing the belt but it was an accomplishment after I succeeded .
Great video dude! I appreciate the detailed and to the point instructions. Thought I would have to take my G37 into the shop but got it done myself with no problems.
Thanks a ton man, I knew I needed a new belt due to the mechanic at the dealer letting me know I had a crack in it when I was getting an oil change but I didn’t know that it was contributing to my ticking noise while I’m idle. Took me a lot longer than the average person but definitely got it done with the help of this video. Thanks a lot.
Parts of your video helped me out heaps. Thanks! I can confirm that you don't need to remove the pulley. Put the belt on as per diagram, then compressor last, helps *ALLOT 50/50* with underneath access too.. Thanks a tonne
For those with limited tools and/or stripped pulley bolts, u can replace it without taking anything off. (Besides coolant reservoir). The diagram he has is misleading for the sedan, look it up on Google, and put the belt on the left 2 pulleys. Put it in the general location it should go on the right, if u have the belt around the 2 pulleys on the left it should have the belt flip (direction you need) which is the correct direction for the tensioner. Grab the bottom of the belt on the right side and slip it through, pull the belt and it should be easy to slip it around the tensioner part!
Thanks for the video. I’ll be getting a 2010 G37 convertible next week. Can’t believe the factory recommends serpentine belt replacement every 30,000 miles!!! The car I’ll be getting has 79,000, guess I’ll be doing this soon.
No, didn’t get it. Something was clunking in the front suspension when I test drove it. Pulled hard to the left. Got a C5 Corvette instead, and I love it.
Awesome!!! I've had the new belt waiting to be put in. Great explanation and video. My belt was starting to show some white threads (not good). I got it done pretty quickly.
Oh man, I want to bday thank you for this video! I replaced my power steering pump but didn’t realize the belt tensioner had that lever. Getting to the pump was difficult enough!
nice work dude! I just realized you are the same guy I used to help me replace the spark plugs on my wife's car. I'm getting that squeaking noise now and inspected the belt. No surprise it is pretty worn out/dry so I ordered a new one. Should be good to go with this video. thanks!
After i hit search and saw that you had made a video about it I thought to myself “man I’m definitely going to be able to do this with his video” lol thanks for always helping out with your videos keep up the good work 🙌🏼
Great video. Thanks, Alex. I was able to finish the job by doing some of the belt guiding thru the oil change panel opening. That way I didn't have to remove the pulley. Keep up the great work!
thanks for the video great information I've been watching quite a bit of your videos I have a 09 G37 sedan I took your advice and bought a sedan over a coupe couldn't be happier also if you let the tensioner go I found that you can also run the belt just as easy as taking the pulley off just because the car that I bought was used and the bolt was rounded off
Funny you say this, I have 11' G37xS and indeed it was 3/8" ratchet...kind of stripped the "hole" , so I ordered a used OEM one off ebay, came today and yes it was 1/2"
My car had 254,000km when I got it. Bought a new belt and pulleys as it had more than 7 cracks per inch on the belt. Which anymore is bad. Drove till 344,000km and finally decided to change it😂 these cars rarely just brake belts, more often a pulley seizes thus making the belt fly off and break
Nice, thx. Btw, Gates makes a new RPM belt model. It's the same part no. you have on your box, but RPM is added to the part no. About the RPM model (from Gates): To resist heat and extend service life, RPM Micro-V belts utilize multiple adhesion gum layers and nylon reinforcement in a patented EPDM compound. The RPM belt’s superior construction produces lower heat, noise, vibration and belt slip. What does this mean for a performance vehicle? Increased durability, best-in-class power transmission and unsurpassed boost!
also on my 09 G37 sedan I Got That Knocking problem and could not figure it out which was no videos at the time so I bought a whole new engine just to find out after I got engine and stalled and all that headache that was just the fuel dampener, maybe you made a video over this or not but I think you should it's very helpful to know if the fuel dampener causes the motor to sound like it's knocking and I found out that all the auto parts stores around me the part numbers do not match up and when you ask for the fuel dampener it is not in their systems it shows an insert one and the top one feeding the fuel rail is not an insert it's a solid piece and it's better to buy the one with the dampener and hose with quick connect fuel line on it then buy it and one piece and try to remove the fuel line and put on the new one at you have all kinds of problems just when you get time read this and write me back and tell me what you think of all these things if you're not sure what I'm talking about research G37 sounding like diesels thanks again your videos have been a great help
Is it the same as the 2014 infiniti q50s VQ37 engine ? But I can't find the bolt from the bottom by the oil pan.. I'm trying to tighten the serpentine belt, please help I appreciate it.
Is it the exact same layout as the vq35 hr? I have a 08 g35. I'm getting a slight wobble on the power steering pulley and some faint noise. Wondering if I could just replace the pulley or the whole power steering pump wich is dumb because the car only has 40k miles on it
Nice video, thanks! For what it's worth, I have 106k mi on an 07 G35x and still on the original belt (which still looks good based on a recent inspection). Although I have a new belt in the garage and ready to slap on, several others including someone that has 170k mi on their G are on the original belt with no adverse issues. So, I am holding out for now. That doesn't necessarily make it smart. But, I thought I would report my experience. We are in the mid-Atlantic area if that makes any difference re humidity levels and propensity for belt cracking (which may be greater in hot desert areas of the Southwest that experience low humidity; again not sure).
My 08 G35X belt with 80k started deteriorating. The hole on the tension pulley on my 08 is 1/2 and not 3/8 like the on in this video. There is not enough space to insert a 1/2 wrench to move the tensioner. The fan motor is in the way. I've tried 4 different 1/2 wrench and spent over 3 hours trying. I'll just have to take the fan out.
hello I also have an infiniti g37 2009 and I would like to know if the parts are compatible with the Nissan 370z because we in France is the misery to find parts and accessories
Hey whats up Alex. I recently used your video to change my 2010 g37x serpentine belt, started the car, now i have a ticking sound coming from the driver side engine top end. I noticed the markings on the tension pulley are not aligned. Any suggestions on a fix?
Great video as always, my 2010 G has headlight clouding issues any advice on restoring the headlights and have you changed bulbs to LED ? Thanks for your help.
Dude I have to tell you! Thank God for this fuckin video! I've been working on my G trying to change my fuckin serpentine shit belt for hours and I almost gave up until I found this video, all the other videos aren't like this one 🤙
Great vid. Thanks man.I'll be changing mine soon. Also, I have a 08 g35 and recently had new battery installed..then next day I noticed when Im at a stop sign or a dead stop and press gas, the car hesitates a sec then goes. Almost like it wants to stall but doesnt..no codes. Any advice?
Hey Alex did you change out the belt tensioner or any other pulleys? Also of people recommend getting a new tensioner when replacing the belt. Thanks in advance!
Thx for the video but I ran into a problem w my 08 G35s. It is bigger than 3/8” ratchet, maybe a 1/2”. My problem is the 1/2” ratchet is too thick to fit between the hole and the fan unit. It keeps jamming up against the fan cover so I couldn’t get the ratchet in the hole to release the tension. Haven’t try from underneath the vehicle yet, figured it’ll be the same problem.
AlexKayRN: Nice job on the video. Q1: before loosening the tensioner to insert the allen key, is it necessary to loosen the Tensioner bolt? Q2: if necessary to remove the idler pulley, what is the recommended torque setting for re-tightening that idler pulley bolt? Also, if changing the tensioner, what is the recommended torque setting for that bolt?
Love your vids Alex! I have the HR 350z which should be identical. I don't have the old belt, can you please give the belt specs? Also I had to do the alternator so I removed the big top coolant line. Do I just top up coolant before I start or do I need to bleed it? Any help is much appreciated.
When I put the socket wrench inside the square hole of the belt tensioner, the wrench got stuck in there and I can't pull it out. I got the belt off but the wrench is still stuck there so I gave up
Great video! Is it smart to clean the pulleys with some sort of solvent or a dry cloth while the belt is off? Any other maintenance that can be done while the belt is off? Thanks!
You can clean the pulleys with something that doesn't leave a slippery coating but I never have. Only thing I would do is check your pulleys for smooth operation. Not much else to do maintenance wise with the belt off.
Cool man great to see so when I have to do it I have some familiarity. One thing I'd like to see is how to replace the headlight assembly bulbs like blinker, "city light", etc, and also how to replace the fog light bulbs.
Hey Alex, hope all is good man, I was hoping if you can drop a link to where I can buy the correct serpentine belt for 2008 g37s mt, I don’t know which code it can be
pull the fans out !takes 20 minutes remove upper radiator hose 2x 10mm bolts unplug and remove the two air boxes now you have a lot of room to work then it takes 10 minutes to route the belt using a 3/8 breaker bar total time 30 minutes vs 1 hour trying to take the belt out and trying to route the belt scrapping up your hands knuckles etc.....
Pooleez ?😂😂 yes siir lol umm wen u got ya g did it suffer heat soak like a lag at engaging clutch at a light cuz my 6mt did ....hated it...lot less now with resonators ditched for bigger diameter glasspacks ..its the underhood cushion i felt it after spirited drive n damn it was hot ...thats why air in the intake is heat charged lol
Tried this today , everything going ok, got the hard part done, tucking the belt under the tension pulley...so everything going ok , then Im all but done and I need just a lil more slack, to finish , Is that normal ??...it was quite tight, and yes I have the right belt...so I check the Allen key and its fine, so I try to get a little more slack, I had a somewhat skinny allen key so I went to change it...FML.....well even with tension from the breaker bar it opens back up....my bolt seems to be stripped now...FML....EDITED...ok ordered a used OEM tension pulley off EBAY for $25, came today got it on...Thanks !!

Lol fuck infiniti goto a nissan dealer they can do anything infiniti can. 110.00 for the belt change still alot just for a belt but way cheaper then 220.00
Thats mad i just paid my mechanic $40 lol
You can also access the belt underneath like when you are changing oil so you don’t have to remove that one pulley and coolant reservoir.
Thank you for this video! Doing a siezed p/s pump replacement, and literally no one has posted these steps. Much appreciated!

Brandon Brown Same engine. Just the back of the car is different
Great video dude! I appreciate the detailed and to the point instructions. Thought I would have to take my G37 into the shop but got it done myself with no problems.
I actually replaced my g37's belt last month without taking off that one pulley. It was simple and fast job. (gates Racing Micro-V High Performanc)
It's definitely doable without removing the pulley I just find it easier and it takes about 5 seconds to remove haha.

Great video. Thanks, Alex. I was able to finish the job by doing some of the belt guiding thru the oil change panel opening. That way I didn't have to remove the pulley. Keep up the great work!
thanks for the video great information I've been watching quite a bit of your videos I have a 09 G37 sedan I took your advice and bought a sedan over a coupe couldn't be happier also if you let the tensioner go I found that you can also run the belt just as easy as taking the pulley off just because the car that I bought was used and the bolt was rounded off
FYI - Mine definitely takes a 1/2" socket, not a 3/8".
doesnt take any socket? its a 3/8 ratchet
Funny you say this, I have 11' G37xS and indeed it was 3/8" ratchet...kind of stripped the "hole" , so I ordered a used OEM one off ebay, came today and yes it was 1/2"
My car had 254,000km when I got it. Bought a new belt and pulleys as it had more than 7 cracks per inch on the belt. Which anymore is bad. Drove till 344,000km and finally decided to change it😂 these cars rarely just brake belts, more often a pulley seizes thus making the belt fly off and break
Nice, thx. Btw, Gates makes a new RPM belt model. It's the same part no. you have on your box, but RPM is added to the part no. About the RPM model (from Gates): To resist heat and extend service life, RPM Micro-V belts utilize multiple adhesion gum layers and nylon reinforcement in a patented EPDM compound. The RPM belt’s superior construction produces lower heat, noise, vibration and belt slip. What does this mean for a performance vehicle? Increased durability, best-in-class power transmission and unsurpassed boost!
Best video on the subject. Great job and thanks.
also on my 09 G37 sedan I Got That Knocking problem and could not figure it out which was no videos at the time so I bought a whole new engine just to find out after I got engine and stalled and all that headache that was just the fuel dampener, maybe you made a video over this or not but I think you should it's very helpful to know if the fuel dampener causes the motor to sound like it's knocking and I found out that all the auto parts stores around me the part numbers do not match up and when you ask for the fuel dampener it is not in their systems it shows an insert one and the top one feeding the fuel rail is not an insert it's a solid piece and it's better to buy the one with the dampener and hose with quick connect fuel line on it then buy it and one piece and try to remove the fuel line and put on the new one at you have all kinds of problems just when you get time read this and write me back and tell me what you think of all these things if you're not sure what I'm talking about research G37 sounding like diesels thanks again your videos have been a great help
Good diy video. Thanks brother! I have an 08 infiniti g37 coupe.
Thanks for the video man. Life saver.
Dude you just saved me thank you! Keep the videos coming
Glad I could help!
Is it the same as the 2014 infiniti q50s VQ37 engine ? But I can't find the bolt from the bottom by the oil pan.. I'm trying to tighten the serpentine belt, please help I appreciate it.
Is it the exact same layout as the vq35 hr? I have a 08 g35. I'm getting a slight wobble on the power steering pulley and some faint noise. Wondering if I could just replace the pulley or the whole power steering pump wich is dumb because the car only has 40k miles on it
Nice video, thanks! For what it's worth, I have 106k mi on an 07 G35x and still on the original belt (which still looks good based on a recent inspection). Although I have a new belt in the garage and ready to slap on, several others including someone that has 170k mi on their G are on the original belt with no adverse issues. So, I am holding out for now. That doesn't necessarily make it smart. But, I thought I would report my experience. We are in the mid-Atlantic area if that makes any difference re humidity levels and propensity for belt cracking (which may be greater in hot desert areas of the Southwest that experience low humidity; again not sure).
Personally, I wouldn't use it for that long, but if it works for you, go for it! I just wouldn't want it to fail unexpectedly.
My 08 G35X belt with 80k started deteriorating. The hole on the tension pulley on my 08 is 1/2 and not 3/8 like the on in this video. There is not enough space to insert a 1/2 wrench to move the tensioner. The fan motor is in the way. I've tried 4 different 1/2 wrench and spent over 3 hours trying. I'll just have to take the fan out.
hello I also have an infiniti g37 2009 and I would like to know if the parts are compatible with the Nissan 370z because we in France is the misery to find parts and accessories
When you take the coolant reservoir off do you need to add coolant and burp it ??
Nope its just an overflow.
bro, this was GOOD info. Ty!
Nice videos keep them up please more on the G !!
Absolutely. Trying to keep up with the content during my move. Its difficult but I'm doing my best!
Hey whats up Alex. I recently used your video to change my 2010 g37x serpentine belt, started the car, now i have a ticking sound coming from the driver side engine top end. I noticed the markings on the tension pulley are not aligned. Any suggestions on a fix?
Thanks for the awesome video. It was a great help with my belt swap
I mess up the square hole 3/8 i need help desperate... do i have to change the whole tensioner now ?
If it won't hold a wrench, you might have to replace it, yes.
Great video as always, my 2010 G has headlight clouding issues any advice on restoring the headlights and have you changed bulbs to LED ? Thanks for your help.
Paul use a decent grit compound and orbital or by hand then a sealer
How tight does your pulley have to be when reinstalling it like torque specs.
Self explanatory, thanks bro .. really helped ! Also very awesome & easy fix ideas from Nissan haha
Why do you have intake pipes going into the stock air box ? Is it to avoid idle issues
Dude I have to tell you! Thank God for this fuckin video! I've been working on my G trying to change my fuckin serpentine shit belt for hours and I almost gave up until I found this video, all the other videos aren't like this one 🤙
Great video man! You saved me some $$$!
Great vid. Thanks man.I'll be changing mine soon. Also, I have a 08 g35 and recently had new battery installed..then next day I noticed when Im at a stop sign or a dead stop and press gas, the car hesitates a sec then goes. Almost like it wants to stall but doesnt..no codes. Any advice?
You ever get that figured out? Alternator, bad (new) battery, clogged fuel filter?
Great video brotha was able to do my belt in under 45 minutes💯🤟🤟
How much do they charge to assemble it ?
Thanks for the video, i need to do this since I have 136k miles on mine and haven't changed it yet lol
Better get on that!
Hey Alex did you change out the belt tensioner or any other pulleys? Also of people recommend getting a new tensioner when replacing the belt. Thanks in advance!
Thank you very very much for this video mate!
Having exhaust fumes issue. When I turn heat/ac on i smell it through vents. 2012 g37 journey sport sedan
Thx for the video but I ran into a problem w my 08 G35s. It is bigger than 3/8” ratchet, maybe a 1/2”. My problem is the 1/2” ratchet is too thick to fit between the hole and the fan unit. It keeps jamming up against the fan cover so I couldn’t get the ratchet in the hole to release the tension. Haven’t try from underneath the vehicle yet, figured it’ll be the same problem.
Nicely done video and helpful tip for my '08 G35XS
Thank you!
How did you get the socket wrench to fit in the idler pulley? Did you have to remove the fan?
I can do this with my 2015 Q60?
any tricks to stick the torque wrench in there? I had trouble with this attempting the fix today
is there any torque specs for the tensioner and idler pulley?
Love the videos bro , don't necessarily have a G37 but I got a 370z which is basically the same thing . Keep the vids coming
Thanks! Yes, this is the same process for the 370.
how long did it take you to complete from start to finish?
Where does the second hose on the coolant tank reservoir go
AlexKayRN: Nice job on the video. Q1: before loosening the tensioner to insert the allen key, is it necessary to loosen the Tensioner bolt? Q2: if necessary to remove the idler pulley, what is the recommended torque setting for re-tightening that idler pulley bolt? Also, if changing the tensioner, what is the recommended torque setting for that bolt?
Love your vids Alex! I have the HR 350z which should be identical. I don't have the old belt, can you please give the belt specs?
Also I had to do the alternator so I removed the big top coolant line. Do I just top up coolant before I start or do I need to bleed it?
Any help is much appreciated.
watch all your vids bro! good stuff!
Would using one of those universal serpentine belt removal/installer help a lot more?
Not necessarily. It may hello you feel more comfortable through the process, like when you loosen the tensioner.
When I put the socket wrench inside the square hole of the belt tensioner, the wrench got stuck in there and I can't pull it out. I got the belt off but the wrench is still stuck there so I gave up
that's so tragic and funny at the same time, about to do mine, hopefully it doesn't happen to me
Great video!
Is it smart to clean the pulleys with some sort of solvent or a dry cloth while the belt is off? Any other maintenance that can be done while the belt is off?
Thanks!
You can clean the pulleys with something that doesn't leave a slippery coating but I never have. Only thing I would do is check your pulleys for smooth operation. Not much else to do maintenance wise with the belt off.
Cool man great to see so when I have to do it I have some familiarity. One thing I'd like to see is how to replace the headlight assembly bulbs like blinker, "city light", etc, and also how to replace the fog light bulbs.
I plan to do some more lighting "mods" soon and will be sure to post!
Great vid but I have a question about the intake tubes. What are they made of and where did you get them?
İ am wondering about how to replace my right exhaust manifold ?
Great vid but I have a question about your intake tubes. What are they made of and where Can I get them? Also do you get a better sound?
Hey there thanks, is changing the g35 belt the same as the 37?
Hey Alex, hope all is good man, I was hoping if you can drop a link to where I can buy the correct serpentine belt for 2008 g37s mt, I don’t know which code it can be
How did you turn that tensioner so easily? I damn near broke my back turning it
Another great job, and ANOTHER thumbs UP!! 😄😄
Thank you very much!
Don't need to get under the car? Gotta do this right now lol thanks for the vid and diagram man!
great video thank you very good
pull the fans out !takes 20 minutes remove upper radiator hose 2x 10mm bolts unplug and remove the two air boxes now you have a lot of room to work then it takes 10 minutes to route the belt using a 3/8 breaker bar total time 30 minutes vs 1 hour trying to take the belt out and trying to route the belt scrapping up your hands knuckles etc.....
Pooleez ?😂😂 yes siir lol umm wen u got ya g did it suffer heat soak like a lag at engaging clutch at a light cuz my 6mt did ....hated it...lot less now with resonators ditched for bigger diameter glasspacks ..its the underhood cushion i felt it after spirited drive n damn it was hot ...thats why air in the intake is heat charged lol
How many miles on the car ? Great video man , you have a video with the noise u had before ?
Tried this today , everything going ok, got the hard part done, tucking the belt under the tension pulley...so everything going ok , then Im all but done and I need just a lil more slack, to finish , Is that normal ??...it was quite tight, and yes I have the right belt...so I check the Allen key and its fine, so I try to get a little more slack, I had a somewhat skinny allen key so I went to change it...FML.....well even with tension from the breaker bar it opens back up....my bolt seems to be stripped now...FML....EDITED...ok ordered a used OEM tension pulley off EBAY for $25, came today got it on...Thanks !!
