Just look at the ribbed side and if you see cracks, change it.

 

 

 

Yeah, look at the ribbed side where it passes over a pulley and bends backwards. That's where you might see the cracks.

I would change it at any sign of wear /cracking on the ribbed side

 

Also even if it still looks good I would replace at time of Coolant flush, keeping the old belt as a spare "just in case". Chane that thermostat at the same time. Killing all the birds with 1 rock.

 

buy quality replacement belts (GoodYear, Dayco)

 

the GM factory belts are also good quality

I would recommend changing an engine accessory belt(s) preventively about every 60k miles. I generally do this on all of my vehicles, although none of them have a single serpentine belt. I fully agree that a good quality belt is the way to go - stay away from cheap belts sold at discount stores, as they will not last and cause you constant giref by loosening frequently and squealing. I have had good luck with OEM belts and also Gates belts sold by NAPA.

 

I case you did not know, Gates also makesl heavy duty V belts and NAPA carries them. These belts are green in color and they are much more durable than a regular V belt, and are generally designed for extreme commercial duty (dump trucks, bulldozers, etc.). They cost much more, but if you are looking for ultimate belt quality, this is the way to go on a heavy duty vehicle.

I agree with some of the above. Change it if you see abnormal cracking. I've ran them over 100,000 before but I don't do that anymore.

I will agree with Pete. These belts are rated to run at least 100K but I typically change them at 60 to 80 to be safe. I am a Gates fan and they are our (CARQUEST) supplier as well. Nothing against Goodyear and Dayco, but IMO Gates is the leader in the industry.

 

Pete, one thing you may not know about NAPA belts by Gates. They get all the Gates belts that will not meet up to our quality standards. :cheers: Hope you know I am just having a little fun.

I just changed both belts at the 60K mark because of multiple cracks in the A/C belt. At first the primary belt looked fine until I took it off to change the air conditioning belt and started looking closer. It wasn't bad but it did have a few cracks in it so it was changed as well. I used the Dayco Poly Cog belts. Keep in mind that if you lose that main belt you're screwed!

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
