Best channel for How To's. Saved me thousands on mechanical services
Finally a series of the truck I own. We'll it's a 98 Chevy Silverado k 1500. Awesome quality detailed videos guys! Love to see everything changed. How bout the spider fuel injection? Or lower intake manifold gasket. How to set up the rear end would be a good one. Or waterpump
Justin Sero sr what size of belt do these take I have a 98 z71 k1500 also
Reason I ask is I bought a singer large case 270amp alt and wanna find out if this belt will fit or what length I need to go .5" longer but don't wanna take it to see then put back on to go buy new one lol wanna have Parts on hand first lol
Why did you totally take the belt off?
I wondered that, too. It's not necessary.
Lmaoo they are making people take longer by doing that 😂
Just a tip if you have to replace the serpentine belt 1998 k1500 ,and you or parts person dont know which fits because there's two . The higher amp rated alernator belt fits no matter which alternator your truck has. It might save you a trip home and the frustration to find what amperage alt your truck has.
Is it imperative that the entire belt is removed? Or could I just leave the belt on the rest of the pulleys while I work on the alternator and just make sure the belt is all in place before tightening?
Girly AK that’s how imma do it.
I have left mine rest on the pulleys while working on replacing pulleys and etc, as long as you get it back on all the pulleys I wouldn’t see why would it be a issues
no need to completely remove belt
No
Thanks, helped me remove my alternator in 20 minutes! Mine was missing the rear bracket, helped with the speed of removal.
On second thought Thanks 1A and 2 other things: 1. I used a 1/2" box end on the tensioner and pressed straight down to free up the belt. 2. The front alternator brackets have sleeves in them. With the old alternator out, I tapped the sleeves back with a hammer to allow the new alternator to more easily fit. When you tighten the bolts the sleeves will again press against the new alternator

Used this video to replace my 1996 GMC alternator. Best tips are to not remove the belt unless you are replacing, and tap the mounting bushings back a little to help with ease of reassembling new alternator.
You guys are seriously the best! Thank you so much.
Great video sound was perfect very complete...
Excellent video! I had a hell of a time with the belt before I saw the diagram right under me lol.
thanks so much, this video probably took an hour off of the install.
I want to say thanks I did everything but the last screw from back I could find it until my step dad took it and he told me about the belt..why you took it off?
I thank you cause I save my self last 250 bucks on mechanic and 150 on alternator . I really want to say that using internet for mechanical work it's the best thing you can do. Thank you now I can drive my car on labor day.😄

Thank You A1 - always informative - 7.4 liter uses 1/2" on everything - bolts and nuts. Tensioner pulley is forced straight down to loosen up to remove or replace belt
Hello, Wanted to know what is the amperage of the alternator some say 124 amp and some say 140amp ? ? thanks if you can let me know I have a 1999 tahoe 5.7L . LT two wheel drive.
Easy job! Love A1auto!
+Mell Sterr Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Thank u so much..i was about to work the brakes off myself and twke off stuff that didn't even need taking off lol..
All those metrics on the “American” truck 😂
That help a lot thanks!!!
+Rodney Rathbun Thank you!
Hi. I have a question about 04 grand prix supercharger.
My alternator on my K1500 is on the left (driver side) of the engine. Is the procedure pretty much the same as the GMC truck in the this video?
Question, why completely remove the belt? Why not just slip it off tge alt' and just let it down, then be careful it's still on right when putting back on?
Good video though... Very helpful...
Does the black cable on the alternator go to the positive on the battery?
Thank you
First off thank you for your help! I messed up though... I'm pretty sure I got the wrong size alternator. What should I do? Please help.
+Sherri Cabinaw If you believe you purchased the wrong size alternator I would not recommend installing it as it could cause issues/damage to your vehicle. Please check with the seller to confirm the part is correct first.
My 96 3500 7.4L has an alternator with a single thinner wire attached to a screw on the alternator that disappears somewhere into the firewall. Any idea what it is for / does? The mechanic who installed the alternator, did not remove the NEG battery cable first, and it 'sparked', and now there is no continuity, and I don't find any blown fuses either. Thank you!
what alternator (100amp, 105amp, 124amp or 140amp) should be used on 1997 GMC C1500 305 motor with A/C and power door, windows ?
Thank you 👍
+Jim D Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
SO... what happens if you dont have that first bracket with the first bolt you took out? My truck does not have that first bracket.
What’s the name of the plug you removed from the alternator
Can you tell me what the wire that clips into the back is for? Thanks
+Owen The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire. The battery positive wire connects to the starter. The voltage sensing wire connects to the battery, and the ignition wire connects from the alternator to the key switch
Thanks for watching.
Didnt have to remove the belt. Just take it off the alternator pulley and move it out of the way. Unless your replacing the belt too
+Matthew Woodbury We appreciate the feedback. Sometimes there are multiple ways to accomplish the same repair.
won't it gain enough slack once i remove all of the bolts r nah?
Dang I want that truck in the video.
The bracket broke when pulled alternator. Have a new bracket, can't find all the bolts!
How many amp fuse do I need between alternate and battery
98 Chevy k2500 5.7, how many amp fuse do I need between alternator and battery
Its funny my old alternator has that salty corrosion on it too. I thought it was because i lived at the beach but i guess its just age on the metal. It doesnt look like you need to remove the whole belt unless it needs replacement
+Drews Quick Fixes Ideas And Hacks Thank you for your feedback!
install video camry 98 please
You really don't need to take the belt off completely
You mean 10mm on that back terminal? Lol
13mm
Every one use E40 I it looses every screw
+edgar rodriguez Thanks for the feedback!
Who the hell takes the belt off..?????????
