Need help identifying part #/ name. Coolant leaking from connector

[Chvytahoe11]

Noticed a coolant smelled and found the source. Looks similar to a t connector with a heater hose line and an aluminum line connected on d different ends. It’s on the left side of the engine (when facing it), close to the firewall.
Need help identifying the part # and name. Thanks in advance!

Heater hose T's. Common failure at age. The aluminum pipes go to your rear heater.
Recommended to do both, though it looks like the other one may have been replaced along with the hose?
White Tee - 15055343
Black Tee - 15055342

Dorman has some aluminum ones that theoretically are stronger.
800413HP (white 111mm)
800414HP (black 113mm)

Get ready to lay across your radiator support and engine to get at these! A foam exercise mat works well for comfort.

The Tees can be tricky to disconnect, but the best practice is to first push the hose/pipe into the connector, and while pushed in, rotate the connector and push in the 2 tabs as hard as you can, and then pull while still rotating. If that does not work, you need to cut them out carefully with side cutters or a small saw blade, being careful not to damage the metal tubing going to the front heater core.

When you change out the tees, be sure to wear gloves, as the firewall insulation is quite aggressive, and your hands will itch for days.

Also, while you are into the cooling system, check all of the hoses (radiator, heater, reservoir cluster), and if they are original (manufacture date is often stamped on them), change them, as they deteriorate over time with the heat inside the engine bay. Otherwise, you risk getting stranded somewhere.

Thanks! I didn’t replace the other t, just the hose. The old one cracked right at the connection with the t.

PS…. Do it soon if its leaking…. Looks like its def of age and you don’t want to be stranded on the side of the road

@mikez71 did use the dorman aluminum ones? Im assuming that pic is of your truck.

First time all I could get was SKP brand.
Looked fine and held up a year or so no problem. Both T's were black, which I like because the white plastic looks weaker to me somehow..

Then I decided to replace them with the metal dorman T's.
I know someone was worried that you won't be able to cut the metal T's apart if the release tabs get stuck..
But I *think* you could break the aluminum catch tab with pliers/cutters if need be.

This is what happens if you don't replace the hoses, as well.

That happened to me, one hose broke before the t started leaking

Thanks for all the help guys !! Got it all fixed up.. did end up cutting the t where it connects to the aluminum line in order to get it off.

Ended up replacing the black t also… that one was cooked !!!
