I never got any of those tools to work on them, there is a trick to it though you have to compress the clips and then yank really hard at the same time. the dealer jXXXX tool might work better but you will still have to yank hard.

You need to push the hose inward a bit, like if you were putting it on, before pressing the tabs in and pulling it off.

Very good point, James.
I will try to post photos in another post below, as I cannot get this Forum's photo post tool to work correctly in this post. One tool is a standalone hinged metal ring (though I saw the same ring in plastic by other suppliers) sold by Lisle, and the other is a set of plastic tools with an angled holders sold by Carlyle Tools (though I saw the same set sold by Lisle and other suppliers).

I yanked as hard as I dared, but after reading that damaging the front heater core requires 8-10 hours of work and a dashboard removal to access/repair/replace, I decided not to yank real hard.
DUDE. I just went through this 2 weeks ago when I did my intake gaskets. I also spent good money on those ******* things at Pep Boys and they were WORTHELSS trying to disconnect my fuel line off the rail. All they did was **** up the clip inside it. SO pissed.

Thanks, I was going to add that Lisle one to my collection, I use the others on the radiator for the transmission and engine oil cooler lines just fine.
yep those things don't work, your better off just saving yourself the time and hassle and just clip the tabs off from the get go.

The two heater hoses arrived, and I installed them, after greasing the both the 'T' spindles and the heater hose quick-disconnects with 90% silicon. I filled the reservoir with DexCool, let the motor run a bit, as you all recommended, then stopped it and let it cool down, and then added some more DexCool.
I took the truck out for a short drive, taking it easy, and everything appeared to be good. After returning home, I checked all hoses and connectors for leakage, and everything was dry. It looks like I can add some more DexCool to get to the cold fill line on the reservoir, which I will do tomorrow morning.
I want to thank all of you folks for your assistance and guidance with this project, and I learned a lot. I've got 50+ years of experience working on cars, but this is only my second truck, so I'm learning about these trucks on every project.
As Hannibal Smith always said, "I love it when a plan comes together."

Sorry, I'm a bit late to the party, but I discovered that the straight ends should come off fairly easily from the heater core pipes. See Post # 17:

Update.
I replaced both 'T's with new GM 'T's, and it was still a royal PIA. I purchased 2 'quick disconnect' tools, but neither on worked, so I might as well have flushed the money down the toilet and saved the commute time to the parts store. I had to cut all of the quick disconnects with a hacksaw blade to remove them in the method that I previously described. To accomplish this task, I had to stand on a step stool, bend over the passenger side front fender, lean down over the motor, and then twist my upper body to the left, to get my arms in a position to access the 'T's. This was real interesting, to say the least, as I had my left shoulder replaced 8 months ago, and it is still healing.
Needless to say, as an old man, I am sore from finger tips to toes today. I even cut my fingers in 2 places, as a result of having to use the bare hacksaw blade. But, a PIA job needs to have the subsequent aches, cuts, and bruises, in order to justify it being a PIA job.
One thing to note for folks performing this task in the future. Wear gloves, as the sound deadening material wrapping the underside of the cowl, over the 'T's has a fiberglass material, similar to old home insulation that gets into your skin, and the back of my hands still itch from the contact with the material.
I've also replaced both radiator hoses and the coolant bypass hose, all of which were original parts on the truck with 2007 date codes. I used new screw clamps, replacing the original spring clamps. I am now waiting delivery of both heater hoses, scheduled for tomorrow.
I have an 02 tahoe 5.3 4x4. She has 300,000 miles and still passes Cali. Smog. No ticks or motor sounds whatsoever. However!! In the last 6 weeks my heater core started leaking, my ac compressor failed and my blower motor died. The heater core is the worst project imaginable. So after pricing all these parts, I decided to just remove all the ac components, climate control front and back, blower motors, heater cores, hoses, wiring harnesses front and rear controls all the way to the fuse boxes. Everything is now gone including every piece of ac component down to the compressor, tensioner, bracket and belt. Everything. She seems to be driving better, at least 70lbs lighter and maybe even a little better mileage. Now I can store a damn sleeping bag in the dash.
Well ok then...
Basic, very basic.........
