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

And it's not just the "tee fittings" that fail. There is a push on fitting that goes onto the one tee as well. THAT is the one that failed on you looking at the pics. Make sure you replace all 3 of them with Delco parts!!!!!

Agreed, the T fitting isn't what failed this time, but the plastic quick connect on the end of the hose.

We are well, and sorry to see this happen. Most of has been through it, or tried to avoid it all together, being proactive and replacing them as part of routine maintenance. When mine decided to fail I was towing my boat and trailer during a thunderstorm through a sketchy ass ghetto. Had to MacGuyver it with my tool kit to bypass the break. Had a gallon of emergency coolant in a milk crate in the back. Got me out of there but still needed to stop for another gallon of coolant at a gas station, I was hoping and praying. Definitely sucks.

I'm glad, this is really a great community.
I've been lucky to not have experienced this sooner and thankful it happened going to work which is about 2 miles from my house. I also fixed it before starting anything at work haha.

Yes, the push fitting failed this time but I did damage the fitting it slides onto when I was trying to remove the original push on fitting. I will for sure.

Thanks for the links, I appreciate it. I'll be ordering everything and possibly doubles "just in case" kinda deal.
What's the difference between the white and black?

Stuck the key in the ignition to roll down the windows to air out the Suburban. End of the day tried to roll up the windows and found out i left the key on and I ran the battery flat. Fortunately, I have the Hellroaring backup battery system (mostly for camping). Flipped the switch and started right up!

Black is outboard and white is inboard with the 3rd straight black connector plugged onto that.

The difference between the two is the angle of the rear line connection port.
