Hose coupling stuck in intake...Help!
On my 1994 Blazer I had a leak in the coolant line between the heater core and the intake manifold. I ended up breaking (not on purpose) the quick disconnect coupling off inside the manifold, and about 2 threads are sticking out. I tried using some channel locks to twist it out, but the material of the coupling just crumbled (I think it was made out of cast or just crappy metal). So I took a #6 spiral easy out and all that happened was that I basically cut threads into the inside of coupling, and the same results with the next size up easy out. The only idea I have left (short of having someone else do it) would be to take a hacksaw blade and cut the coupling into sections, BUT I am worried that 1) I could mess up the threads and 2) that the filings could cause some damage to the cooling system.
So after the long novel (sorry), are these legitimate concerns OR is there another trick?
Also I do not currently have a garage or a lot of time so taking the intake manifold off and drilling it out or something similar isn't really an option.
Thanks for all of your help in advance!
