....only odd thing i hade go on me that is coolant related is the heater hose that loops into the intake of the truck, the connection at the intake was leaking, and when we noticed it leaking we tried to see how loose it was, and it blew completly off the intake (engine was warm and running) Because i did not have the funds at 17 to take the engine apart and put a new intake on it, dad and i picked a thread-on connector out of a 84 monte carlo with a 305 in it, put lots of teflon tape around it, lined it up as best as possible, and threaded it in.
If you're talking about the quick connect, that's not odd at all, but very common for them to go bad. There's no reason to install a new intake.....unless you totally screw up the threads trying to remove the old fitting. I've had a standard brass hose barb on mine for years now.
