Replaced the serpentine and a/c belt, along with the tensioner and idler pulley. Bought it as a kit last month because in cold weather my tensioner/belt makes a funny noise.

The belts actually looked decent, no cracks in the ribs, so I'm keeping them as backups. Who knows when they were replaced last. I bought the vehicle in August 2018 with 105k on it. One owner trade-in on new vehicle at GMC dealership, so they might've replaced them before they put it up for sale.

Took me a while to figure out the Lisle stretch belt tool to get the old belt off and new belt on. I was just going to cut off the old belt, but the numbers stamped on it indicating the length was about 2" longer than the new one, so I wanted to save it in-case the new one didn't fit and I could put the old one back on.

Also replaced the autoride air compressor. Those metal wire clips that secure the air lines are little bitches to get back on the connector if it pops off. I had two of them do that and after spending about 20 mins f*ing with it finally figured out a way that worked well and was able to do the other one in like a minute...lol.

All total took about 2 hours

Store the belts and the tool in the truck. On my ex-work van, I had a tiny pebble wedge itself in between two ribs on the A/C compressor pulley and shred the belt. I was three hours from home when it happened. That was also when I learned about the stretch belt.

Looking at used engine hoists, this popped up as suggested.

it would require my hoe to make a good 600 mile round trip.
But my in-laws have a condo down there...

Guess i could store it in their garage until the hoe is done.

:hmmm2:

One should NEVER go on a road trip with no tools.

I wonder if they make an adapter to go from the lug nut size to the crank bolt size. With this, you could use the factory lug wrench or one of those extendable lug wrenches as a long-handled wrench. All you'd need is to weld a 22mm bolt head to the back of a 24mm socket, maybe a cheap cut-down HF impact socket.

Hell naw. This was during the summer, of course. That was a loud and hot drive back home. Had the windows down, but the wind was just hot, wet and sticky.

Got me thinking about doing the ac compressor again.

July is going to be a trip to the coast in the hoe.
It would suuuck to loose ac in the middle of it.

So converters for the 6l80
Looking over circle d's stuff,
I see a good looking option for under 1k
https://www.circledspecialties.com/gm-300mm-hp-6l90-ls-torque-converter-2
states a twin disk lockup


And then the rest appears to be over 1k
Like this option with triple disk selected is over 1300
https://www.circledspecialties.com/6l80e-pro-series-265mm

I suspect it's overkill for my intended use.


What one is everyone buying?
:yuno:


Unless your going to build a 1000 rwhp rig, no need for those big twin disc verters.

I got the Circle D 6L80 3200 stall, only option I pony'd up for was the billet where that makes the converter stronger.

Around town, drives like a stock converter...............now when you put the pedal down, its fun. Its like the best of both worlds.

Or....take a 24” long 1/2” drive breaker bar and a couple sockets.

I can make an adapted like that or just have the breaker bar and socket. There may not be room for the lug wrench anyway.

I need to setup a dedicated kit that stays in my truck again.
