What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Just Fishing]

and working some motivation.
rainy and cold today.
but my garage is insulated.

Even more insulated since i added AC this summer.

I need to work out a cover/insulation for the AC unit.
then time to go fill some propane tanks...

Hoping i'll get motivated enough to drop the front axle, ps rack, and maybe even the pan.

If the thrust bearing surface looks good, i'm tempted to just order another set of bearings.
Sure would be awesome to do this just one more time.

If it looks questionable, then it gets the original 5.3 thrust bearing.

if it also looks questionable, then i'm probably ending up with a new crankshaft.
So that means new bearings all around, so no ordering until i have it opened up.

Even though the 5.3 and the 6.0 cranks say are identical, GM lists two different part numbers.

And everything fit perfectly with the 5.3 crank, everything seemed to line up perfectly as well.

but if it gets replaced, I'll probably spring for the actual "official" 6.0 crank.

Then i get the fun of a re-balance!

Picked up one of those small glass vials used to test Ethanol content.

What's the best method of getting a sample?

And I do plan on replacing the radiator, until then I'm running with that bypassed.
I'm pretty sure the new radiator won't have the little GM ports installed (I'm looking at an upgrade 2 or 3 row).

I'm also thinking about replacing the OEM "tow package" cooler in front of the radiator for good measure.
That comes with the little e-clips.

Can't go wrong with the cold case, so much better than stock!

Yeah, the tow package cooler is a small sad piece of junk compared to any aftermarket coolers.

I've only done it once, and I removed the core from the Schrader valve on the fuel rail, slipped a piece of hose over the nipple, put the other end of the hose in a small cup and turned the key on for about half a second. It didn't pump much fuel at all into the cup, but was more than enough for the sample in the vial.

I've gotten really good at pumping gas all over my hand. lol

I bought some tiny funnels from harbor freight and use a mason jar to get it from the pump and poor carefully into the test kit.

from the station pump?

Prefer to get it from the vehicle so I can compare it to the virtual sensor.

I didn't know what the best way would be, either via the Schrader valve on fuel rail or by sticking a thin hose down the fill tube, or maybe some other way. Figured I'd ask the people that have experience in doing this.

just use the open end of a fuel pressure tester, it will come out under pressure so just use a bigger container to capture what you need

After the car cools off some, we pull the engine cover and the cover for the fuel rail and attach this brass adapter a turn or two. Then we press onto the barb some 1/4" clear plastic tubing we have at the house (barb is 5/16"), about 5 or 6 feet long and then screw down the fitting which then depresses the schrader valve and fills the tubing with fuel. Then I begin to pour the fuel into the beaker until it hits the full line. Hopefully not too much and hopefully I remembered to put water in their first!

If the car has recently been driven, there's usually enough fuel in the rail to get a full sample without turning the key on to refill the rail.

I'm all set to do this too but it is pouring down rain these last few days.
