I have the same set. I’ve had them for probably 15 and only used less than a dozen times. Worked every time.
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

The other problem is the part that clips on the spark plug, if the wire is installed without dielectric grease and left on for too long ( sometimes plugs aren’t changed for years) that metal corrodes to the plug and no matter what you do, the metal clip won’t release from the plug. It destroys the wire because the clip stays on the plug.
This is why when I did my plugs last week I went ahead and got wires too... not knowing the history... and yes I broke 3 wires... but now the plugs and wires are all brandy new...

True story. Did anyone suggest he have a set of new wires on standby?

Pretty sure I did but in a different thread.

Good looking out fellas. Got the pliers in between the metal cover and the boot. Yanked hard and came right out. Ended up tearing off some of the aluminum Took me about 25 mins for all 8. Took an extra 10 mins of plug 8. Dreading getting that plug out.

Welp, ran into another issue. While trying to get number 8 plug off. My arm hit a tube and came off. Coolant everywhere.. tube doesnt fit back into its housing.

Scratch that its red, transmission fluid.
no, that's coolant, those t-connectors get brittle over time and break, you can get a cheapy part to just reconnect it with a hose clamp but it's recommended to replace it with a new oem hose

What's the part number for the hose?
well according to murphy's law the other one will break soon so may as well do them both, these are the parts you need
all 4 pieces

New tires... 305/35r24 pirelli P zero
That will work for now, but I would recommend getting the oem parts at some point they will last longer
No it's red coolant. Those fittings are a weak spot, should have warned you. The same ******* thing happened to me when I did my wires. You can get new dorman crap pieces from Auto store if you are in a hurry. There is a company that makes aluminum tee's but they are expensive as hell. In the mean time, you can cut that crimped end off the hose, and slide it onto the stub that is left and clamp.

Any idea on how to remove the broken piece off the end part?
Where the 2 flat thin plastic pieces are snap those off with those bent nose pliers you used for the plug wires, then it will slide off sort of, there kind of a *****, you may end up having to just break little pieces off until it comes off
this piece on both sides, then you can try squeezing the white clip in and then pull on the connector
once you have that off the new one just slides on until it locks into place
if there is enough plastic left just leave it and slide the new hose over it, if it is already broken off too short then you will have to replace the T
