Gruven heater core T-connectors

[j91z28d1]

I just did this on my truck. I ended up using a small saw from my friend to cut off those crappy connectors. Ill go with the gruven maybe next month when i address every hose in the cooling system. But what about the rear? I didnread that the rear heater core has some problem with the line breaking or something.

I have the plastic replacement ones for the rear. Dorman seems to be the only ones in that size. I got the part number off here. but I haven't got around to replacing them.

another guy had a hard time getting them off and the hose on the other end is a factory crimp fit to metal pipe. doesn't look fun job and I got lazy. I can look up the part number if you need it but they are plastic

I did my rear heater hoses, and modified the OEM heater pipes. No more crimp fitting. Also use the Dorman fitting, 3/4 in to 5/8 hose barb

This is where I trimmed the heater pipes above the spare tire

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.

I didn't see this info posted but you can get that Y separate now dorman part number 47157!
