What did you do to your NBS GMT800 Tahoe/Yukon Today?

[MassHoe04]

Washed and enjoying my new wheel hub bearings and alignment.

Looking sharp!

How hard is it to disassemble and clean an original starter.. Is it worth cleaning up or just replacing. Not having any issues but it is very dirty and have to remove it for access to crank sensor

Replace it. If you don’t, it’ll fail as soon as you get it all back together. Getting it back in is a little bit harder, but very manageable.

Dirty outside or in the gear works area on the inside?
If dirty on the inside, why? Rear main seal leaking into flywheel housing?

Tips: Jack it up on a stand, remove the wheel. Pop the plastic fender liner and fold it back out of the way. Makes for much easier access getting hands on it from bottom and the side that way.
Yes it can be done on the driveway from the bottom without doing any of that, but why make things harder if you don't have to...

Starter is easy enough to remove and install. If nothing wrong with it, I'd keep running with it. Old originals are good until they die and may last longer than you expect. Might be better to have an old one rather than a new reman. starter.

I had a leaking rear main last year, since been fixed. Going to be replacing several things including crankshaft sensor above the starter so that's the time while I am in there to decide. Deciding between keep original, new acdelco starter, reman acdelco, or reman denso

Unbolting and moving the starter out of the way is different then totally removing it. In my 4WD to get the starter out I have to try a gazillion different ways to get it to drop down sometimes I get it quickly sometimes it seems to take forever to get it down so I can disconnect the wires. As far as cleaning it, shoot some degreaser on it call it done.

 

[MassHoe04]

I thought removal and install of replacement was easy, especially since I took the wheel off and opened up access through the fender liner. I was done pretty quick and don't recall struggling to disconnect wires, get them out or back into position.
Was like a half hour tops.

But yes, if just cleaning... I agree.
Unbolt it and just swing it out of the way. Be sure the battery is disconnected, so you don't arc out on anything while moving it around. Spray it down and run it.

So recently had my tahoe tuned and had them do an e85 delete. I unplugged the sensor, now I am getting a code p0178.. hate seeing that CEL

Make sure you remove the oil dip stick, it will make your life easier to remove the starter

Does anyone have a subscription to Alldatadiy? I need the wiring diagram for the starter circuits

Here is a good tutorial..

But remove your battery first. You would not be the first who burnt down his car, while trying to remove the starter...

I ordered a new accumulator/drier, orings, orifice tube, and compressor. My A/C compressor still works, but is a bit louder than it used to be and I've noticed the cooling doesn't seem to be as good as it used to be during the height of summer. Hoping some fresh parts and a recharge will get the HVAC back to operating good as new again.

I’m just getting into tuning, but why? Is e85 not readily available?

My truck runs like a turpentine cat on e85 and would only get better if those tables were also tuned, but maybe that's not possible?

I don't use e85, and when I replace my fuel lines I plan to remove the sensor.
So I believe in my tune he turned off the sensor but didn't delete the codes that report a fault with the sensor

Same.. I LOVE corn gas!! Unfortunately it’s not available within 90 miles of me, but I may just pickup a few gallons here and there in barrels..

Turpentine cat - that's a new one. I usually say like a r- aped ape.

Heh...I learned that one from my father in law after we changed the plugs on one of his vehicles a number of years ago. I had never heard it before.

Was it @iamdub who wanted one of those sensors?
