Cant het the pulley off

MAsterr Serch says:

Jesus what a pain in the ass…
But if you like puzzles (and cars), it's a fun time!

Also, most videos I saw just show the alternator part, not the WHOLE process, which was what I was looking for….thanks!

Literally sent all evening trying to do this, got everything except for that pulley and belt tensioner. This car is a pain in the ass to work on

I started a Jeep repair channel and I wish I could streamline it like your channel. All steps and issues covered in detail. Perfect content! Great job!

casey palmer says:

Yea this is way better than moving the ac compressor out the way thanks

Joe Yannece says:

oh for the days of my Chevy V8. The alternator right on top, three bolts, one belt, one electrical connector.
I can turn a wrench, but this one is out of my league.

Excellent excellent video. I work on vehicles a lot and you give great tips tricks and explanations of this entire procedure without extra rambling. It's nice to know what I'm getting into before I start a project and this video is top-notch. Great lighting and video angles. Thank you

Yo bud could you do a video for AC compressor replacement from start to finish the same car Nissan Altima 2002-2006 3.5 V6. 95% of the videos out there are for the 2.5 4cyl this video was such a huge help. There are still a ton of the third gen's out there.

SuperFlyers14 says:

Thank you so much man your video was spot-on not only was it easy to follow I was able to get the exact tools that I needed before the job so no sudden trips to AutoZone. I just wanted to point out two things that I think could help everybody that's about to do this job: 1) after you reinstall the radiator recheck your main alternator electrical connector that's in the front. Even though I triple checked that I snapped it in when I installed the alternator it came undone when trying to jiggle the radiator back into the front of the car. The big hose really bangs around all the electrical connections when you're reinstalling the radiator. So my alternator was only running about 50% and since I was sure that I clipped it in earlier I thought for sure there was something wrong with my alternator. As soon as I clicked it back in all the way alternator worked awesome perfectly at 14.2-4 volts while running . 2) after you reinstall everything and turn on the car when you turn your thermostat to hot and turn on the heater if the fan is only blowing medium but you cool air you need to rev your engine several times. I had to do this in order for the fluids 2 get up to the heater core and start blowing out hot air. I could literally hear the fluids swishing around right behind my radio where the heater core is and that took care of everything . they must have gotten trapped for When I close the hoses at the start of the repair but just revving a few times cleared it in the heater was awesome. especially since I live in the Northeast and it's 15 degrees right now.

Would this work on a 2007?

Brock Temple says:

Can you tell me about a high pitched whine noise on that same engine please??

Jeremy Saenz says:

New battery new alternator same kind of car and I’m getting a brake light and battery light and car did the same thing on me and died any clue what it could be? Fuse bad wiring?

Alpha Diallo says:

I think u don’t have to take out the radiator just take out the fan but I understand just more room

scientist100 says:

That 14mm bolt that is under the alternator was rusted in my case and did not want to come off. We are stuck with that bolt not wanting to turn after it did just a lite bit.
