Is this the heater to tank hose?

[DavidZ71]

One last issue. The Dorman quick disconnect attachment I bought for the heater hose to core connection isn't correct. Doesn't look like my Tahoe actually utilized the quick disconnects (that's what I get for not checking). Do you know the part number for the white plastic connector? I've attached photos showing a comparison. Black is the Dorman connector.

The white Dorman is this: https://www.rockauto.com/en/moreinfo.php?pk=9769688&cc=1424247&pt=6876&jsn=917

It's the size that you need that makes the difference.

Thanks! That looks more like it. I ordered it and should be here Saturday

Hope you got the Delco or GM ones. The Dorman ones are specifically known to not last very long and you might be doing it again very soon.

I ordered the Dorman one. We'll see how it fares!

I had to replace my heater hose the other day. I was driving when it broke. Coolant everywhere in the engine compartment. After replacing the hose, I added 1 gallon of coolant, I disconnected and reconnected my battery to reset the engine trouble light. No light, but now my water temperature is very high and so is my oil pressure. Anyone have any suggestions as to what else I could now have an issue with?

I went with Dorman because of cost and availability. AC Delco and GM ones are on at least a two week back order from what I was told.

The Dorman "T's" are the parts to stay away from. The quick connect hose ends may be OK

Dorman does not have a good reputation here at this forum.
