Gruven heater core T-connectors

[Geotrash]

Thank you, Ken! VERY helpful. I'll order the Dorman aluminum part with hoses as well.

Cheers,
Dave

DARN, I wish I would have know about that Dorman hose Dec.24th when one of my plastic t-fittings broke. I had the GruvenParts.com aluminum t-fittings in hand, but I changed that heater hose with one from NAPA, and that Y fitting is plastic. I'll buy the Dorman and install that aluminum y as soon as possible

Ok,, so I think i'm going to do the dorman part mentioned earlier for the
single Tee with heater hose assembly.
But, when I look up the heater hose Tee , they list one that's 111 MM and one that's 113 MM... How do I know which I have (without disassembly first). I have 2014 Yukon XL Denali
Thanks for the help!!

The straight connector is not needed for trucks with rear heat.

You CANNOT use a Gruven T-connector to replace the Y-connector down by the water pump BUT you can buy the Dorman 626-553 which is a direct replacement made from aluminum. That is what I used.

The only way you can buy it is with hoses. They don't sell it separately, I called Dorman and asked.

Hey Ken will this work on an 07 esky? I just ordered my gruven T's and will be putting them in soon

Yep, sure will.

I noticed the Dorman t connectors are 2 different types(1 is black the other is white) the gruven t connector fit both?

Yes. You can use 2 black or 2 white... the only difference is they have a slightly different angle on the side that feeds the rear heater core.

How was the quality of everything else else like the hoses, clamps, plastic connection?

I assume you are asking about the Dorman part... everything seemed to be of good quality. I used the entire Dorman assembly... aluminum Y-connector, hoses, clamps... except for the plastic quick connect fitting that goes to the factory plastic T-connectors obviously .

Got my gruven T's installed today, had to trim the hoses up about an inch going to the heater core and actually had to trim back the hard lines going to the rear of the vehicle about 3/4". Other than that, it's a great product that's going to hold up well

I tried uploading photos, but they're too big and the site won't accept them
