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

[TheAutumnWind]

The bulbs that came with the fogs are 899s which are 37w vs the factory 880s @ 27w. They are better... But id love to find leds that match my headlights which are d1r (the later escalades came with stock hids) osram "cbi" @5000kish.

I wouldn’t vacuum line it yet. I would hold off on changing oil put some seafoam in the oil for a week also dump some in the gas tank if you run it through the vacuum line it may loosen up too much carbon and then you’re going to block everything up. Don’t touch the O2 sensors unless you’re changing asking for trouble

I just put in some in the oil during lunch today planning on changing it tonight. My only free night to do it.

I will wait unitl I do a full tune up to do the intake, thanks. Besides i need to chage

Edit you could change the plugs after you seafoam oil and gas mbut seriously would not vacuum line it

Thanks, I took your advice. I ended up just changing the oil last night. Forgot I Seafoamed the gas tank too. After a day of it running through. the idle is smooth as glass again.


I was going to drain and fill my rear axle fluid, but there is no drain plug like I have seen on youtube... WTF. I guess I now have to remove and replace my rusty-crusty diff cover, already have a replacement cover sitting in the garage. I cant find replacement bolts anywhere for the diff cover. I will check NAPA later.

Why not use the old bolts? Just clean them up.

I guess I could put them under the wire wheel on my bench grinder. They look like hell. The original owner towed his mid sized sailboat that saw saltwater boat lunches yearly, so my undercarriage is UGLY.

You dont see a little plug with 3/8 square in it on the rear? Look again...a 3/8 ratchet with extension fits it

A vinegar soak will loosen up rust and whatever else. Id try that.

Never heard that one.

White Vinegar will dissolve rust on metal.. even better is applecider vinegar.

Yeah I most definitely have never heard of that either and I am pretty good with those types of home repair ideas. For instance.....never wire brush your battery terminals. Get scolding hot water out of your faucet and just slowly pour over terminals and white crusty buildup. It will all just melt away leaving you beautiful clean metal contacts.

Changed engine oil and trans fluid. Silky smooth.
