Heater hose “T”

[89Suburban]

Need to come up with a “locally engineered solution”… if the ones on the firewall are susceptible to failure, these are as well. May start carrying 2 hose clamps as an emergency measure in case of failure.

Here are some options:

Growing up doesn't have to suck

... Did all that to make way for these: Shipping might would've been a little cheaper had they not included the duplicate bag of hardware.:rolleyes: I guess my Tahoe is now officially for track duty only: Long tubes? Short tubes? My answer: Neither! Tri-Y tubes! I don't know...

The T's for the rear heater are not serviceable separate. They are part of the rear heater lines #1.

which appears to be

and it is shown as ac line, but is actually both ac lines and both heater lines including the T"s
which from all appearance look like they are indentical to the T's for the GMT900's

Reviving this older thread...
Does anyone know which specific part # would replace the plastic tees on a 2016 Yukon XL 6.2 ?

it might be worth a gamble to see if the GMT900 T's will fit
the part you seek is 84524267 or as shown below

basically you have to buy all this pictured crap to get the T's

BETTER PIC

found one listed on ebay as "new" but is obviously open box because someone bought it just the the T"s apparently lol

Insanity. Just the tee's alone in the beginning on the earlier platforms, now all this on the newer ones. Sad.

the lines are fine it's just some moron decided that they shouldn't sell the T"s separate which is a complete waste.
If I have to order the whole aux line set for $209+ tax and shipping, then it will most likely all end up in the garbage except the T"s
I'm probably going to order the K2 heater hoses and the gmt900 T's and see if the hose fit's the T's, if not then I will have a spare set
if the hose fits then the aux heater line should fit also
The service manager from my local dealer is going to call me in the morning and I am hoping he will know if they fit or not.

guess I found the answer, according to this video the same T's fit, I think this guy is speaking Portuguese or something but he used a 15055342 and it plugged right in

service manager from my dealer called me back this morning and confirmed in the shop they are using the same GMT900 T's but... now the white one and black one are swapped to the opposite side because of the way the aux heater lines are angled going to the rear.

@JMH1980
they use the same T's as the gmt900's they are just swapped position to the other side so the white one goes where the black one was and the black one goes where the white one was. 15055343, 15055342
