[@brianmason1414]

You not see the belt and still willing to post, is AWESOME! Guys like me always think that guys like you in your world, everything must always go so well because your so knowledgeable. Just had an Audi that doing voltage drop testing saved me from replacing an alternator! Unfortunately the testing found a bad battery cable that wound up being almost 3 times the price of the alternator, but, in the end, the car was fixed correctly. Yes, I have the paper version of your book!!! :)

Great video! FYI, Nissan has the drain plugs in the bottom of the rad. They use a flush plastic plug that used a Philips head. Also, I’m glad to see that you take working on cars safely, seriously.

Dear Mr. Danner; In an interview with the Rosedale Collage president, you mentioned something that made sense to me and stuck in my memory. Something in effect that “the mistakes that you do burns in mind”. Thus, I would bet you will never check a charging system again without doing a visual check of the components. Especially the belt. NOBODY is immune to not making mistakes. NOBODY is perfect. After all we are human.

[@brandonb8543]

Thank god even guys better then me can make similiar mistakes! Bet the first thing Caleb checks when diagnosing charging systems will be the belt. Thanks for leaving the mistake and the bucket of knowledge you share.

With all the diagnostic info in the front of your mind,it’s very easy to momentarily overlook something simple. Especially when you can’t even see the component in question. I’m gonna say you noticed it at the appropriate time. Its the guys that would put on a new alt and can’t find the belt I worry about

[@dtnel]

Good Edits! On the R&R keep in mind certain people might mistake you for rest and relaxation if they're a first time do it yourself home DIY guy. Those of us who've sweated thru the grease and rest of it all knows it means remove and replace. Drain in the little thing at the bottom. They hide them from the diagnostic guys.... "It's so Rad" the Rad may not have to come out lol. OMG the belt. That's not your fault, I bet the Transmission shop had something to do with it, maybe missed it. Would make sense. Hope they didn't replace the Transmission due to no power to a solenoid and how the heck could they do a complete trans diagnostic and replacement and not make sure all systems are good as long as it sat? No need to be embarrassed as we all are learning. Why do you think dr's are "practicing" medicine all the time. Maybe a video on that would be a good topic or even a livestream on KZbin Paul. That would be a great idea. Safety first with the stand to keep from falling. Yes I'm replying as I watch so I'm going through it with you. Gates had a new belt checking plastic tool for the keyring out this past Feb at the vendor show I went to where I got lured into the buying Bosch ADS-625 or as the wife says "Another Toy". What's your neighbor doing? Woodworking or something? Noticed he quit after you said something about "that" but then the mower comes along... ha ha... Hope it wasn't him as well. One thing I want to point out with the coolant leaking you touched on earlier and you can address oil to is parts stores sell absorbent blankets which soak up any loose fluids that spill. I bought some and they work great. They make single and large packs of them. They're even good for that car with a drip every few days and protects the garage floor. If just coolant and it leaks and you don't have a pack of or any single absorbent pads and you spill some coolant you can get the water hose and dilute it really good. Do we want to put it down drains ? No but if in driveway and only solution that is a option to keep the critters out of it and safe. Good short easy fix. Also you can use the bright orange, bright green , black, white or whatever color gloves you choose. Keeps oil off the hands and it feels just like working without gloves with dimples for grip. I use to love the oeabge then found the bright green cheaper on Amazon. One last thing Paul. How do you bill this one out as it didn't need a alternator but needed more than one belt. Me I'd charge initial diagnosis and belt replacements only as we and you know you had more time In in but the video with enough views will help the loss long term. I offered my daughter camera woman duties this summer and said when we hit enough views to get something she could get all the money for her college fund and I'd have no problem helping her make videos. Yes she won't make it overnight but with regularity we could build something for her future. We'll have to see what she decides as school gets closer and closer to her senior year. I don't blame her for wanting to stay cool inside but she'd be inside korea than I as she can come in and edit. Anyways, Nice fix and honest which in my eyes you may not have had very many honest people about that one. It's about doing the right thing and you did! 👍💯💯💯💯 for real! Oh BTW it's Amazon Prime 2 days so better get your gear and software if you need any.

[@olvincontreras9103]

ScannerDanner I got a 2005 Honda Odyssey the battery light is on the alternator sometimes charging and sometimes is not I just bought a new alternator I haven’t put it on yet I think the belt is still in there but I’m not sure that if the belt is cracked would cause battery light on any tips

I appreciate this video so much for the minor/major oversight that we all have made. The way you go about diagnosing in your other videos has made me rethink and modify my approach to testing systems. You always talk through your diagnosis and your thought pattern and thinking the problem out loud is the most enjoyable to watch. I will be purchasing your book and subscribing to the premium to learn a few more tricks, I already bought some new "toys" from AES to complement the tools I have to emulate some of your tricks with my old trusty Modis that I have kept simply for the scope and the obd1 cables that it came with back in the day.

[@parochial2356]

Paul; if I never blew a diag by missing something obvious, I would have my own "The Perfect Tech" KZbin channel. I would emphasize to Techs to check the alternator belt tension as part of any charging system evaluation [just as you should always check the A/C compressor belt on any no/low A/C cooling complaint] [Same as with checking the water pump belt with a hot running/overheating complaint, when so driven]. I have seen a loose belt cause a no/low charge issue before. In checking the belt tension, the fact the belt was awol would have been caught during initial diag. Thank you for your candidness. We all need to be reminded once in a while.

Ahhhh, Scanner Danner, Thanks for the comedy. I remember about 4 years ago i had an intermittent charging system on my 1990 Ford ranger. It would charge, then stop charging. "V" belt system. did the checks, yep not working. I went to parts store (20 miles one way) bought a 150$ alternator and set about changing the alternator. I went to pull the belt, found the problem. The belt was there, but the "V" portion was gone, all that was left was the flat part of the belt. I did buy a new belt with the alternator, so i just slapped it on, and 4 years later, still running the 1990 Factory alternator. You arent alone. As a young tech 20 years ago i was in a hurry to install a transmission in a chevy truck, stabbed it in place and went to hanging parts on the transmission ARGH!! i forgot to put in the torque converter.

It's called low hanging apple (easy problem).

[@johnaclark1]

Bulb circuits can be tricky. I put a reman Denso alternator on a 2013 Honda a few months back after it failed. Did my full diag and condemned the alternator. When I started it up the battery light was on but it was charging just fine at 14.5V and carried the car's full loads. I questioned my original diag but then after diag'ing the light specifically, I correctly called a bad replacement alternator. I've never seen the light on while charging before. Customer told me (after the fact, of course) that the lady behind the parts counter dropped the alternator on the counter.

[@frankthomas2231]

If you had done the alternator, I think you would have found you would have pulled the radiator too. I have done a lot of these on Muranos and Maximas with the 3.5l and they are all the same chassis. You may have been able to get to the alternator without pulling radiator, but for the extra few minutes it takes to remove, it is worth it for the extra space it gives you. Also, FYI the radiator drain plug is on the very bottom almost directly below the cap. Factory radiators usually take a #3 phillips to remove. Aftermarket radiators may have something else. I just did a 2006 Maxima alternator 2 days ago.

[@fascistpedant758]

It may be on more recent models, but I've replaced them on the 3.5l by dropping the engine 1/2" and pulling them out at the front of the engine.
