Broken heater hose connector repair
Folks, thanks to your recommendation I was able to rebuild my 4l60e transmission myself and finally got around to installing it this past weekend. In the process discovered that my heater hose connector to the intake was completely corroded and had broken off. I’ve seen plenty of how-to’s that chip out the remnant thread bits, but these are all done with the intake on the benchtop. Is it possible to do this with the intake still installed? I’m wondering if something can be stuffed into the hole in the intake to prevent too much debris from entering the system. I say “too much” because this truck is old and already has a rusty dirty coolant system that I’m not too worried about gunking up with powder/shavings, just large bits.
Thanks, alex

Re: Broken heater hose connector repair
Commercially-available "special tools" are available for exactly this purpose.
Discontinued, but some still exist in the wild. https://www.lislecorp.com/specialty-...ler-repair-kit  The removal bit from the tool set, above, is Lisle 62200--still produced. https://www.amazon.com/Lisle-62200-H...7085809&sr=8-1 I replaced my rotted, leaking original GM connector with the Dorman replacement more than 20 years ago. After nearly 20 years, the engine was replaced. The Dorman coupler still looked "perfect" so I re-used it. I'm not promising that Dorman still makes that coupler to the same quality standards...but it's worth taking a risk on it. I think it's this one. Please confirm. https://www.amazon.com/Dorman-800-40...s%2C320&sr=8-7

NAPA-branded version of the Lisle removal tool kit, priced advantageously. I just bought one.

Re: Broken heater hose connector repair
Thanks for the reply folks. I ended up using a hack saw blade and screwdriver to chip out the remnant bits. Nicked up the threads a little bit but got the job done. Then the ½-14 NPT tap cleaned up any remaining debris. The Dorman coupler threads in nice and seems robust. Truck started and runs without issue – thanks!
