Above are the two greatest links you'll ever click on when educating yourself about high output alternators. This Mech-Tech-Truck video I touch base on why we use our 1.75" high output pulley's and options for those that should NOT run the smaller pulley and keep the stock sized belt. On to the next one!
it's next to impossible to get a hold of this company I have been having problems with my alternator for months.
Really? Call us RIGHT NOW. Message us on Instagram....Facebook.....OR HERE! You could also do this super crazy thing by going to www.mechman.com and clicking on the CONTACT US button. We're literally easier to contact than WalMart.
Also, did you know in all of MY video's I state that if you need help/assistance you can EMAIL TONY@MECHMAN.COM ?
Phones been ringing all day, Nick. Still have 2 Techs and a salesperson ready for whatever you may need.
Just re-checked my social media messages again and nothing there.
Checked my Tony@Mechman.com email and don't have any unread/unresponded to emails.
Now, we are an actual business and not a guy in a garage cobbling alternators together and painting them, so we will be close tomorrow(Saturday/Sunday) but we'll be in the same place we've been this week on Monday.
I'll still be checking social media over the weekend on my own personal time, but thats no biggie. That's what I'm here for.
Where are you Nick? We've been trying to get ahold of you all weekend and now today/Monday?
No emails, no social media messages or even on Google messenger. Just one of the 5 ways we can easily be contacted.
Still trying to get in touch with you Nick, where'd you go?
Great info for those that do not know MECHMAN FOR THE WIN FTMFW!!!! I got a 8 yr old 370 smd with external regulator on my Yukon never ever have had an issue with it EVERRRRRRR!!!
So what you're saying is that you installed it CORRECTLY? This is revolutionary!!! :)
@@mechmanalternators lol I usually pay to have them kinda things installed which I did in the astro van it was in at first got rid of the van bought a Yukon and I installed it personally in there but I use my alt for my boomin system 😎🕺🏾🍻🍺
Let me chime in here since i just had a "life Alternating" experience,
So the old stock" 130A alternator finally died on me in my 2002 Escalade AWD 6.0 after buying the truck from a private seller - he did mention that it may need some TLC down the road, so i went to Advanced Auto where a certain A-shmole" was working the desk trying to counter my info i needed to get a replacement "OE" one all part numbers matched up and model type.
Put it in my truck and bam as soon as i started driving fast or aggressively it gets a low volt reading from the volt gauge in the dash, this was my first time having to replace this part, so i was stumped for a few moments, thought maybe it could be a bad battery, crapped out "new refurb" alternator, maybe a ground came loose somewhere, etc etc, then I went online bought a 250A overland spec Alternator and a 250A fuse with 0 gauge wire booster. i even had new shops test the 130A alternator and my battery to rule out which one is causing the problem they both said the battery was good and the alternator was fine, but for some reason i didn't believe them (strange gut feeling), put my battery back in the truck and tossed the advanced auto 130A alternator in my toolbox -
So anyway back to the 250A Alternator, I installed all that in about 3 hrs since i had to figure out how to upgrade my positive battery terminal as it needed "some changes" and as soon as I connected the negative, i heard a faint electrical crackling through the truck from the front to back - like the truck was being baptized with power - then when i started it, damn the 6.0V8 engine had a better aggressive start, healthy, and the stock bose sound system sounds better overall bit more bassy and clear, now i can accelerate faster, hills aint nothing anymore, and just the performance as a whole is great now. This Escalade feels brand new to me just by installing the higher output Alternator.
Deff my case using a high output alternator may be different from others, I've been working on car since i was 14, I am now 47.
but glad i did this to my escalade, it was worth it.
Cheers and keep learning out there
Just got my new 370 elite for my ram 1500 with the 5.7 hemi. Love the look but I have not done the install yet. I’m trying to use the website to find the new belt I need but it won’t let me click on what I need to get it done. But what I was thinking was, why not send the correct belt out with the chosen alternator.
Because we do not know the vehicle options, year changes, year breaks for that specific stat. Idler pulleys can vary in size from OEM to wear/tear replacement items over the life of the vehicle. I can keep going on and on.
The GM SUV/TRUCK belt chart in our FAQ's is only like 99% right. We still have an occasional disgruntled customer because he has the 1 of 20 vehicles made that year with NO A/C and the whole system is different.
The best we can do is give the customer all the necessary tools and information to ensure a proper fit.
I just checked the link, seems to be working perfectly fine.

Realizing that this company Making the best aftermarket alternators out there i put my order in for a custom 250A billet.. hopefully i get it soon and explain why you should choose a mechman over the competition
Certainly appreciate that kind of feedback! We just try to sell what we think will benefit the customer to reach their goals. We use a few of the same parts as others but vetting, R&D and expansion is what keep us going to be better.
The reason changing belts is scary specially on boat engine is because not all belts are made the same and it's already difficult to find the original belt so getting smaller belt might be ok initially but what if they are no longer available in the future. My example is for a Volvo Penta 5.7 belt is part # 3862665 if you have the part number for a smaller belt that will work I'll definetly buy this alternator for my boat.
Belts are belts, if you're breaking belts then there is something wrong. Goodyear, Bando, Gates, Dayco, Continental....they all works as belts should.
Good explanation.
For any body with a 6.2 LS motor regular belt is a 635k6 I put a 630k6 for my mechman alternator works perfect 630k6 because the mech man has a smaller pulley buy the 630k6 belt done
Just double checking. So I have a 2021 silverado 6.2 with a stretch belt your saying 630k6 is the perfect match for my 400 amp alternator with the smaller pully.
When are you guys going to get into the PCM controlled charging system cars almost everything is becoming PCM controlled
About a year ago.
Hey I have a 2021 gmc sierra 1500 5.3!! I'm going to install a mechman 400 watt in it but I have a stretch belt so no pully tensioner!! Would I have to buy a shorter belt and special tool?
Did you ever find the right belt for your truck?
What belt for my 370 i got from you would be best for my 6.0 escalade, I am still using stock?
Just didn't even read the description that gives you the info to find a belt, huh? 🤭
@@tonyb022377 dammmmmmm lol
I put half inch shorter belt and it squeals when I turn the AC on...I can almost fit a 1 inch shorter belt on there... spring tensioner shakes in idle but doesn't move when I hit the gas....any ideas?
You always go buy your tensioner marks/markings. It needs good forward/backward movement in order to adjust properly for varying loads.
So - with the install of the big three or four and with the install of a new high powered amp, not much discussion in what size fuse you should use from that high powered alternator to the battery. This is a key point due in fact that fusible links are there for a reason. With the install of a high powered alternator, larger cables are required and are often replacing the factory cables. Question: what size fuse would you put between that High Amp alternator and battery?
Well, a fuse is there to simply cut power in the event of an accidental short so if you have have a 400 amp alternator, any fusing over 400 amps would be perfectly fine. Fusing is fairly straightforward when knowing the rated amperage of the alternator...or so I thought.
@@mechmanalternators Unless the cables can’t handle 400 amps. 1/0 are roughly 250 to 280 amps continuous… then the meltdown and fire happens
@@stevenm.hollis4429 I think you need to do a lot more research. Start here: 4xspower.com/support/amp-chart/
@@mechmanalternators thankyou
@@stevenm.hollis4429 yep had one this morning!!!!
😁👍🏼
I went with a inch shorter do you think that is to small I didn't have no problems putting it on no squeaks are nothing like that
If it works, it works!
just bought a 240 amp for my 2003 suburban lt 1500. Did everything as stated on the instruction except change the belt. Is this the reason It drops to 13-12v on Idle? I don't have a sound system the only load I have is from the e-fans I installed to remove the clutch fan.
Correct. Alternator can't work if the belt is slipping. Much like a burnout....it looks cool but not as fast as the guy that hooks and takes off. :)
@@mechmanalternators wow thank you for the fast reply.. just bought my new belt 1/2 in. smaller 92 3/8 (stock was 92 7/8). looking forward to swapping this out this weekend💯😊THANK YOU
@@jmunoz1414 how do I determine a smaller size belt because my vehicle only got 2 sizes only one with A/C and one Without A/C
How short of a belt should I buy 1/2” shorter or 1 “ shorter?
Mine is a 2012 gmc crew cab 5.3 liter 2 pin alternator alternator works great I did 3 quarters of and inch shorter then stock got it on there it's super tight for sure I'm at 14.5/14.4 at night time everything workin great buuuuuuutt cant get the dang battery light to turn off dang it that does bug me I have 3 voltage meters the one on the dash my stereo head unit alpine iLX-F511 also tracks my voltage and I have a sundown auto amp on the bass knob that also keeps my voltage everyone reads the same and yes I bought the 2 pin module i have the 370 amp billet alternator that comes with the bypass module but just cant get that battery light to turn off I haven't contacted mechman yet I'm waiting for my new battery to come in just installed it on 5_6_22 recieved on 5_2_22 but do I need to maybe disconnect the ground to the battery to reset the computer or should it turn off as soon as I plug in the modular then should the battery light turn off ...??? Like I said could be the battery or maybe my module isn't working properly 🤷♂️ but the alternator is BAD A$$ I'm running about 4 thousand watts 4 little DC 8 inch woofers and at night pushing those lil guys and dropping down to about 13.3/13.5 at night to me that's amazing cause everything in the vehicle is running so I am very happy
You need to make sure your ONLY ground from the alternator is passing through the vehicles RVC sensor on its way to the battery. Review our recent video's for a "how to"......or use our instructions included with the alternator. :)
@@mechmanalternators yes sir it is 👍
So I just installed my 240 amp alternator for 2010 Acura tl is it normal to make a faint generator sound?
Yes
What size belt you used? I bought a 320 alternator and still haven't installed it haha, plan on installing it this weekend but haven't bought the shorter belt yet, I also have a 2010 TL
Tony! Why don't you sell a larger pulley for the idler so people can use the stock belt? Just a though to help people overcome that problem of being intimidated by needing a non standard belt. It's an easy addon sale and will help customers feel more comfortable knowing they'll be able to find a replacement belt without having to get something non standard.
Use a top quality bearing and make the pulley steel or aluminum so the bearing can be pressed out so they can rebuild it for under $20. It's just another quality upgrade you can offer. Idler pulleys wear out. You can give your customers an opportunity to replace them with something better than factory instead of far worse than factory like pretty much all of the aftermarket pulleys are and maintain using the stock size belt.
It will fly, even for replacing the other idler and tensioner pulleys they keep stock size. A set of Mechman hard anodized aluminum pulleys color matched to those bitchin' alternators, maybe black or polished aluminum finish...???! It's a no brainer to buy. Consistent design aesthetics when they pop the hood. Longer bearing life. Lower rolling resistance than crappy bearings. Love it.
Shoot me a message. I'm more than happy to accept a big ol' gift amazon card for the new product line idea! (but only because I don't need a big alternator right now!)
Now that i'm here.....there are "things" in the works. :)
@mechmanalternators let me know when yall come out with this idea pls haha
I got a 92.3 gates belt fact. Belt is 93 hope I got it right
Check our FAQ section and it will tell you :)
I just took mine to my mechanic last week and I noticed he didn’t use the pulley that came with the alternator he used the oem pulley is this going to cause problems??
Probably.....I mean, it will certainly put out less idle and cruising speed amperage. We install the correct pulley for a reason.
@@mechmanalternators well dang smh thanks for the response
What size belt do I need for 2011 Silverado 5.3
Just didn't even click the link, huh?
😆Sure didn't!
@@PurpleNovember LOLZ
wait it need a ground, a smaller belt and switched power? wtf did i buy lol
And believe it or not, it does not work off of Bluetooth! You ba'leeeve that?!?!??! :)
@@mechmanalternators no bluetooth??
A BAD ASS ALTENATER!!!!!
A real man’s alternator lol
What if u can't find a smaller size cuz they just don't make um
Then you're not looking hard enough
