Had some chirping or squeaking noise from my accessory drive. Decided it was time to change out some stuff before it broke down on me. #chevy, #silverado2500, #diy Music Credit: Goodie Bags and Power Cord by Dylan Sitts
Just did this on my 2016 Sierra 2500 6.0. Took less than 30 minutes to do all three. Has to be one of the easiest engine compartments I've ever worked in.
This is a first class "how to" video with some heads up on some things the other videos don't mention, like not putting your wrench too high, etc. Great video and very helpful, thanks for making it.
Thank you SO much for the video. I was curious if I could do it without removing the fan shroud and fan. You showed me it could easily be done. Had to do the same to my truck today and you helped a LOT! Good video my dude. 💙
First numbers on the belt are mm in length. Second numbers identify number of grooves (97% use 6 grooves). Cracks in belts are normal and every shop uses these cracks to scare you into buying a belt. Bearings in pulleys do go bad and if experienced, you can use a wood dowel, long screwdriver or mechanics stethoscope to listen for the bad one. (Note) the tensioner has large heavy internal spring. If belt wears, it stretches. Marks on the tensioner will become closer together indicating time to change, not the number of cracks. Yes, it drives everything except A/C compressor or other on most, but the belt grabs and holds so tight even when worn, say the front alternator bearing freezes up solid, the engine may stall at idle and won't crank as if the battery, cable or starter had failed. Check with belt removed before replacing these parts. Just a warning for spending $$$$ on a good part, when the root cause is actually another failure. DK, ASE Master Tech since 78.
Good info Dean. Yeah I’ve used the long screwdriver trick a time or two. I thought my sons car had valve train issues until I poked around and listened with a screwdriver. Turned out to be an alternator bearing. Much cheaper and easier fix than head work
I probably could have done that on these. They weren’t that bad. I kept the original ones for spares. Who knows, they might get regreased and end up back on once the new ones wear out, lol. Thanks for watching!
1 more reply schaeffer grease is the best my dad has poultry houses thay are hard on fan baring most other farmers replace baring often but we wint 10 years and 1 baring is all we replace the desal oil is what mad us a fan in the first place but most farmers don't use schaeffer grease for the price
You don’t have to but if they are available and not too expensive it’s a good idea. You can try working some grease into the bearing on the pulley that you replaced as well. Sometimes I think they need a little more than they came with
@@jessemendoza2991 never noticed a hum. Really only noticed it when it sat at idle after I started it each time. You may be able to take the belt off and turn each pulley or accessory by hand to see if it has play or feels like the bearing is not smooth. I’ve had alternators kind of hum or growl if the bearing in them is bad
