I’m working on a 2020 Silverado 5.3L. Came into the shop needing a higher amp alternator for a ramp being installled in the bed. New vehicle to me and when I went to take off the serpentine belt I see no tensioner......asked around the shop and no one had any answers. Has anyone ran into this at all. If so I would appreciate your help.

There is no tensioner, you need a specially tool ridiculously named a Universal Stretchy Belt Installer (GM EN-51767-2 - Universal Stretchy Belt Installer).  Gimme a few minutes and Ill get the write-

Not following the logic of wanting to add back in a tensioner.  The stretch belts have been on the AC compressor and vacuum pump on the 14-19 trucks and they worked great.  The serpentine stretch ones

Its actually really easy with a Stetchy Belt all purpose tool.  Lisle has one and you can see how easy and quick it is to use.

I tried the Lisle tool.  Does not fit on 2019 Trailboss crank shaft pulley.  Called some dealerships - they wont sell me the blue Stretchy Belt Installer pictured above due to patent.  Not having a tensioner in there is borderline retarded.  Good luck.  I'm stuck in my own driveway like a genius.

Not sure if you have room on the T1, but my l83 K2 truck used a stretch belt for the brake vac pump. I used zip ties as I didn't have access to a stretch belt tool once i was in there. Cut the belt off of course. Worked perfectly.

Thankyou for your reply.  Good advice.  I tried this about 10 times.  There is so much pressure that it snaps the zip ties.

Yeah I had to use some pretty large ones, but i bet that serp belt is a lot more to pull over then the small vac pump belt I did. Good luck!

Thanks.  I've modified the Lisle tool to fit over the lip of the crank shaft pulley.  Will give it a go.  If it doesn't work I will have to take it into the shop and have them do it.  Not a lot of options for me - live alone in remote mountain area at 10k ft, foot of snow on the ground, no garage, below freezing outside - there's only so much of that I can handle when I'm lying on the frozen ground with 20 mph cross winds.  it gets old real quick like.  Absolutely ridiculous.  Had an old Tahoe I drove to 300k miles - so easy to work on....same 5.3L V8.

Just did mine last week. 7 normal size zip ties for serpentine belt. 2 broke, first one when it was bout ¾ of the way on and second when it was right at the end but it got it done. I would buy some decent zip ties if u r in colder weather cause I know the cheap ones tend to break very easy when they r cold.

Well that's the idea, right?

 

Eliminating the tensioner will make the company several million dollars per year, just in parts alone.

 

If they make 1 million cars, and they save $5 on each one by eliminating the tensioner, how much more money did they make?

 

Making it impossible for people to work on the vehicle at home will make the company millions per year.

 

Advertising will making the company billions per year.

 

They are not making vehicles for any other reason than to make money.

 

Money money money. Tha's what its all about.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.

      Fix one problem and find another.   Truck didn't have a thermostat in it so I flushed out the system today and refilled with 50/50 Dexcool. This truck is so old (LOL) that it has a sticker under the hood alerting people to the fact that it contains such. There is also an orange supplement with the owner's manual alerting the owner that "Your vehicle is one of a number of late production 1995 General Motors vehicles that use a newly developed engine coolant in the cooling system..."   I was still a little flummoxed by what seemed like a rich condition (exhaust smell, and a puff of carbon with a punchy rev). While watching the coolant temperature and testing the thermostat with my scanner, I happened to notice the IAT (incoming air temperature) to the intake was -40F. I know the temp is below average today, but I can still feel my face, and I was wearing shorts.   D'oh!! I realized I had never plugged the IAT back in, and the airbox was out while I was doing coolant. So I paused, reinstalled the airbox and plugged in the IAT, and viola. Things cleared right up, and I watched the coolant temp climb to a reported 198 degrees on the scanner (195 thermostat) and then it dropped to 194 (open) and then back up to 198 and held. Let it cool, came back, checked the coolant level and was satisifed.   Victory lap?   It needed more than the couple of gallons of gas I put in it from almost bone dry, so I ran it up to the gas station. It had earned it, or, at least I was pretty certain I wouldn't be draining or removing the tank anytime soon.   CEL popped on just as I was cruising a nice steady 40mph, just after coasting down a slight downhill curve.. Of course, it did, because, why let me enjoy not having dash emojis for a little while.   I just happened to have the scanner plugged in. I don't text and drive but I might scan and drive. Don't tell the police.   P0401, EGR flow insufficient.    Well, hello, EGR... ...my old friend! Welcome to the party, now that the engine reaches the factory-programmed operating temperature. I'm sure it was gagging on hostile, rich exhaust and carbon this whole time so I'll take it off and look again.   At least it's easily accessible, and worst case, about $65 to replace.   To keep, or to sell... Hmm. I want it running correctly either way. It's easier to sell when there are no fault codes.   It needs tires (they're aged out and cracking)   It could probably use an oil pan seal, or maybe the timing cover gasket/ junction with the pan needs redone because I've got an issue there that leaves a drop of oil on the floor.   If I do tires I'm sure they'll say the ball joints could use freshening, and, and, and, and.... At some point I'll have to stop. I can't (shouldn't) make it perfect, that's not what this rig is.
