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

yep

Nothin better than the smell of diesel fuel, beer, and debauchery!

Used to watch those back in the day at the old Spectrum stadium in Philly. Place was the size of a tin can with a roof. Talk about noise and fumes. Good old days.

I’m from backwoods lmao so we go to “Redneck Hill” at the local fairground and watch em or Highland County has one like every Saturday night during the summer and it’s really in BFE

JB Leather weld update for those who care, it’s not by any means perfect but it’s much better than the hole! Most of the ugliness is user error and I know that lol

cleaned blower motor, discovered my ac evaporator was filthy, mud in there from the dust and condensation i guess. sorry no pics im traumatized. might be good to replace heater core after all.. plus i thought i smelled coolant again this morning.

How long of a process was that from start to finish? Not counting the traumatization…

 

[j91z28d1]

wonder how it will hold up

 

[Sparksalot]

took 88 there and back stopped in pine grove at Gianninis for dinner haven't been there in like 20 years, price was decent $106 for a full course meal for 5
had one guy on the way back doing a pretty good pace in a accord (i think) but I am a challenger so he let me pass him and then stayed behind me for a while but couldn't keep up lol funny I'm pushing a 6000+lb tank thru a curvy mountain highway and nobody can keep up?
around 8 hours of highway driving and still sit's on 10.1mpg
I usually get a little better mileage thru the mountains but passed a bunch of boats near the end that probably wiped out any gains I had

Dang, that’s some memories. Some of my high school friends worked at Giannini’s. You know a few weeks ago.

Well, I'd say it was an hour for the blower motor only. (do-able in 30 mins)

Two screws on the little drain channel part (Same size as the 2 blower resistor screws.)

Odd size hex head screws I think it's 5.5mm, I had to use a smaller E torx socket. Maybe E8-E9 I forget...
but the screw that came with the filter kit for the block off panel was even smaller, possibly E7.
so a set of those little sockets is handy, $10 from harbor freight.

There is a little tab on the edge of the motor casing that you pry as you rotate the motor and it pops out.

You can pry the squirrel cage off with a couple prying tools. I used a scraper on one side which scratched the back of the motor housing (no biggie) and a thin piece of wood on the other side (to pry evenly) It takes a few prys, but you will notice it slowly sliding off as you work around it..

I used mostly a tube brush to get in there between the blades. Toothbrush a little lacking, but good for the nubs on the edge.
Then I blew out the motor with air, I'd recommend doing that outside, lots of fine brush dust or something will form a cloud.

Then you'll want to clean the insides so it will take more time!
I had the blower resistor off, and cut a hole for the filter.
The filter hole lets your run a wet paper towel/sponge in there with a long screwdriver to wipe the sides of the case.

Also put a hose on a vacuum with an angle cut to vacuum the evap core.
Also put my air nozzle in there to blow around the loose stuff, who knows how much stuff I blew further into the system, but some dirt did fly out the accessible side.
Turning on the fan later, I didn't notice any dirt flying out the vents.

So all told, I spent at least another hour, but I was cutting the filter hole and cleaning the blower resistor just because it looked a little crusty
Still plan to soak the core in some 409 cleaner.. but if I still smell coolant, I'm just going to wait until I gut that thing and replace heater and evap cores..

I don't know if it would make a mess now that you cut the filter hole. but I've used one of those cheap pump sprayers with some water in it to stick up in there and spray out the dirt and stuff from the core. it didn't have enough pressure to hurt anything and not enough volume over flow the drain. even thou I won't lie I've used a garden hose before inside to spray them out haha. but I didn't car much about that old car.

8h drive at 10mpg hurts my soul. your kids better love you for it lol.

I haven't wanted fire works that bad since I was 10 and my parents wanted to smack me because I wanted 10$ worth of jumping jacks haha.

Went for a drive.... nothing fancy. No work today so I loaded up some broomsticks and went up a Class 6 road to some power lines to find a quiet spot for stress-relief.

We've had a ton of rain lately, and the "road" is usually doable in 2wd, but it was so wet/muddy I actually had to twist her into 4-Lo. After that it was slow and smooth.

I use some evap cleaner and a long hose attached to the end of the cans nozzle. Soak the hell out of it and then run it to clean out all the build up. Be sure to have a catch pan handy.

Then I saw the photos. Boom-sticks! Got it…

when I was a kid a lot of this stuff was legal but that's all changed depending on where you live, I have always enjoyed blowing things up lol not in any kind of menacing way just for fun. light and run is the rule....
it's a annual trip for about 20 years now, a couple of times I picked them up in washington state instead while visiting family the tribes along the coast have them and seal bombs, those are fun. Also one trip to New Mexico as soon as you cross the border there is a huge warehouse with lots of fun stuff! never have seen any like the one's in Tijuana though but you couldn't get those across the border if you tried.
even a trip to the east coast was sketchy they are legal in one state but not the next I bought some I forget where and was driving and didn't really think much about it until I went to light some off and was told the closest place was Pennsylvania so off I went lol, crossed the border lit them all off and took off for New York the states over there are so small, drive down the road and you went thru 3 states already.....lol
as far as mpg. that's all I ever get doesn't matter what I drive, even if its a little 4 banger I will only get minimum mpg
the more you push the big pedal the less mpg you get and I am just not a slow poke

 

[Doubeleive]

going to take a trip to Yellowstone next month I expect I might get 12mpg when it's all said and done but likely less, will probably vary along the way places like Idaho is sketchy to speed thru, lots of little 1 stop sign towns and bored cops with a 25mph limit where there is literally not a soul in sight

funny, I don't think I've lived In a state they have been illegal, there's always some work around where you can buy them but can't really light them off but it's over looked 2 nights a year. maybe why I never got into them much. no one told me I couldn't.

here it's not illegal but they ask that you not to because it's so dry you get fires if you look at the grass wrong.


I guess I drive really slowly. I got 13 on my last trip towing a car on a trailer and was a bit bummed cause I was expecting more like 15. but the buddy's with diesel said they only really get about 12-13 towing in real life, the same trip too, so I didn't feel as bad.

I've been wondering if I open the exhaust up a bit and the intake if I could stay in high gear more while towing and do better. high rpm just wreaks mileage and my tranny is very happy to increase rpm if you ask for more power

I don't think opening up the exhaust will do anything but make it sound different.
gearing might help like 3.73 4.10

I just grew up with fireworks always had firecrackers because you can get tons of them for cheap, neighbor across the street had a real cannon he was a pretty cool old dude with acres of old cars all over his property and he could care less if we explored all over, he would fire that cannon off and man that was fun times.
nobody complained, was def a different time period
