Amazes me how many people still think the dealer is a good place to get your vehicle fixed.

It’s not?
When I ran shops, if I needed to hire a tech, typically a dealership tech was my least favorite hire. I did get a few that were good techs but the majority of them were guys/girls that had been trained to do just enough to do a job and they were not concerned with comebacks. So many knew "shortcut tricks" that were not conducive to quality work. Give me a tech that had worked in a family shop atmosphere any day.

There are tools available to disconnect those connectors, but in my experience, none of them worked effectively for me. Folks on this Forum have recommended to first push in the connector and rotate it slightly. Then, while pushing in the connector, push in the two tabs on the connector and pull them apart, while holding the tabs pushed in.
If the above fails, then you can take a pair of pliers and break the connecting plastic piece on the connector, just below the tabs.
IMPORTANT: Wear a pair of gloves when working on the Tee connectors, as the insulation on the firewall is quite aggressive, and you will be itching for the next few days.
Also, be sure to replace ALL heating and cooling rubber hoses as part of this project, as you will probably find the original manufacture year stamped on the hoses.

Don't fret, some of our friends here have not seen how high prices are these days for labor. Just like going to a doctor or lawyer, you are paying for their expertise.
I just bought half the hoses needed to replace all, $150 for GM OE and will be ordering the other half soon. I reckon I better just go ahead and replace the radiator too, all that yanking on the old hoses is likely to split a tank from the core with my luck!
Most dealerships have highly trained professional mechanics that specialize or are very familiar with the vehicles you bring to them.

Been looking, but cant find a thread that details all the part numbers needed to complete the Tee and Hose replacement.
I found the black GM Tee: 15055342
The white GM Tee: 15055343
The heater core GM hose: 22885825 (appears to have the crimped on quick connector to attach to the 15055342 black tee)
My question is the last hose. The one with the built in Tee in it. It is a GM 18221L ?
And if so, it doesnt appear to have the connector crimped on for the heater core tee.
So, would I also need the GM 34000 for that connection? Or does it simply slide onto the 15055343 white heater core tee?
