This is the best video I've seen so far. You just saved me a $2,000+ mechanic bill for doing just this. I'm no mechanic, and there's a reason people don't trust most of them. Good job my friend.

[@DIYKAI]

Thank you! Yes, unfortunately that is the case many just want to get the customers in and out like a revolving door to make profits. I always said treat the customer right and treat the vehicle like your family was going to drive it and you will never have a problem with business.

At 4:29 the hose you describe as an AC hose is the power steering high pressure line. Mine leaked and I just had to replace it. Great video. Anyone have any advice as to why my bank 1 runs lean? STFT maxes out during acceleration.

[@DIYKAI]

Thanks it’s wrapped like an ac line lol must get stupid hot. Lean would indicate a possible vacuum leak or something after the MAF sensor…other possibilities fuel related but less likely

Great job, your thoughts on a used 2013 Nissan Maxima with the cvt transmission and 150 k.

[@DIYKAI]

Thank you....cvt transmission are ok as long as they have been serviced and don't have any weird noises or "moaning" when driving...they are not meant to be a speedy trans more of an economical type.....if your using it for an A to B car then yes its fine

[@DIYKAI]

@@jt8280 exactly just use the manufacturer recommended fluid

[@APBtDiezel]

Gotta 09 myself.. had it since 2016 and only problem was the cvt but Nissan extended the factory warranty and I was just shy about 1k miles of the 120k at that time. 88k miles when I first got it then at 115??? I believe trans started failing, sounded like a supercharger or power steering whine. Wonder why they have a CVT light on the dash 🤷🏾‍♂️🤦🏾‍♂️ that never comes on unless it’s about to start. CEL light came on for the trans. And everything dealing with the change of the transmission was covered, new exhaust pieces and a coolant flush.

[@DIYKAI]

Nissan CTV trans are troublesome they have to be babied and trans fluid every 30k to last

Really don’t need exact as it can be done by feel. 3/8 ratchet for the plugs when they stop turning 1/8-1/4 turn further…manifold bolts same except 1/4 ratchet 1/8 turn after contact…. Can provide specs later

What size spark plug socket did u use?

[@DIYKAI]

@@user-um5sn5un3z no problem

[@BLACKMONGOOSE13]

Question, if you’re still monitoring this channel. If one ignition coil is bad, should they all be changed? I know it’s significant expense with them being $100 apiece but this is a pretty involved maintenance procedure.

[@cryzur]

You can get them for $20-60 per coil on rockauto. O’Reillys and AutoZone charge an arm and a leg for parts.. but yes, I’d definitely recommend changing them all out just so you don’t have to go through this process again. I ordered 6 coils even though I’m getting an error code for 1 of them. After taxes and shipping, it came out to less than $150 vs paying $600+ at autozone or O’Reillys

[@DIYKAI]

Yea rock auto has great prices

[@DIYKAI]

Honestly if you can’t afford all of them just do the rear bank that is covered up that way those will be done and out the way the other ones are easy to change

[@patriciagarza5151]
