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

[Sam Harris]

Finally got the efan conversion done! Also replaced alternator, idler and tensioners for the serpentine and a/c, and new fleetrunner belts for serp and a/c. Running like a champ! Not feeling any seat of the pants difference really, but just drove her home from the shop. Thanks so much to @Fless for sourcing the fans!! I also got a response back from Scotty Boy recently, so will eventually replace the junkyard harness with his cleaned up junkyard version. Hehe.

Nice Sam! Did you do it yourself?

I was finally able to check my oil pressure with a manual gauge. That was an ordeal in itself.......
The oil pressure gauge kit that I purchased has about a dozen different adapters EXCEPT the one for LS engines!! After a quick Google search, it seems many oil gauge manufacturers do NOT include this adapter. Rather than order the needed adapter and wait several MORE days before I can test it, I decided to just make my own adapter by drilling and threading the old oil pressure sensor that I removed from the engine. Other than the cheap Harbor Freight tap handle breaking in the process, this plan worked out great. I was finally able to test my oil pressure once and for all and much to my dismay, the manual gauge reads the same exact pressure as the dash gauge, around 8-10 psi. I just ordered a Melling high volume oil pump abs screen kit, which should be here Monday or Tuesday, along with all the gaskets and seals that will need to be replaced in the process. So, the saga continues.........

Sorry to hear. I hope the pump or o-ring is the issue.

I did it with help from my buddy, in his shop. Lol. Even using his lift for the a/c tensioner & belt, my back is an absolute wreck. I had planned to do it all myself, but my back just can’t take anything these days.

Don't use that 100k oil on your Speedo, it doesn't like it. Lol

Sorry to hear, I was hoping it was feeling better. I wanted to give your post a like and a sad lol.

Looking great! One of these days I need to get back out to a Upull or two to see what I can find. A fan conversion would be awesome!

Bought these for nothing.View attachment 352895
The center of the hub separated, but the hub end piece is stuck. Not even budging. Beat it with a mini sledge--no dice. View attachment 352897View attachment 352898View attachment 352899

Axle is out.View attachment 352896
Would heat help to get the back end off the spindle? Any suggestions or ideas to get it off?

Oh man, that blows! I always knock one of the lug studs out and then use a bolt through the stud hole with a nut on the back side to push the hub free. Not gonna work there unfortunately...
