Broken Heater Hose Assembly at Intake

    GMs are infamous for the heater hose connectors breaking off at the intakes, leaving the threaded portion in the intake. Does anyone have any suggestions on how to remove the threaded portion from the intake?

    I have attempted to use 2 pipe extractors, one was to large the other to small.

    Well, you need to get the right tool for the job. Get the right size and it should come out. Spray a little penetrating fluid on it also if it is stuck.

    They usually snap off because their corroded, as stated get the right size and try that, if thats not possible I have had success removing them by using a dremel tool to cut a slit down the inside of the portion threaded in and chipping it out with picks or a screwdriver.

    +1 had to do it years ago in my '97. buy the machined one to replace, not the cast junk!

    The cast pot metal is the problem. As mentioned, dremel, chisel, pick, whatever you can use. I think you can get a repair kit at Napa too. The extractor might not be much help at this point, but the tap to clean the threads would be useful.

    Tapped the outlet on the intake and used J B Weld to fix the part of the intake that broke. System is holding water and working fine.
