Rear heater core connections

[JimW1999]

Looks like either the fitting or rubber hose just below the fitting has a pin hole. This is the connection to the rear heater core. How do you take off those connectors to the heater core? Looks like a special quick connect, do I need a special tool? I'm thinking of cutting the hose and putting a regular hose clamp or spring clamp on it. I think the core is still good so I'd like to repair it rather than bypass it.

Doe the connectorhave 2 plastic clips on each side?
If so push in and plull off.
Parts places have plastic coupler for rubber hoses and some times the couplers.
Let us know how it goes.
Good Luck

get rid of the connctor and replace it with a hose barb and clamp. it will end of failing on you after time.

I did this successfully a few months ago on my 1994 Suburban because I also had a leak there (under the front passenger door). I broke/pulled off the end of the hose, didn't want to try dealing with the GM engineering. Then I cut off that connector, and used a standard stainless steel hose clamp to connect it. I did loosen two of the clamps that held the more-rear part so that there would be enough hose as to not be strained, moved it closer a tad, and secured the lines with cable ties.

I think GM engineered this in this way, was so that if the lines needed to be removed, that one could avoid the hose clamps/cutting off the hose ends.
