Coolant Question 5.7 LT1

I had a coolant leak in the thin metal line that runs from rear of motor up along the head and turns into a hose that goes to reservoir. It got a pin hole in it. It was near the rear of motor. I needed a quick fix so I had to cut the metal line out at the leak, and clamped a hose to remaining line. I lost alot of coolant, and I know it sucked in alot of air. I have been adding coolant, and using the bleeder in front. But it still is running about 5 to 10 degrees warmer than it usually did. Its not overheating or boiling in resevoir.

So is there more than one bleeder on motor ? And would replacing the metal line with hose be a reason ? If so, where does it go behind engine, and does it come off to replace ? I can't see or feel just where it goes.

If no other rusted areas I would leave it, if you can park the car nose up leave the rad cap off overnite, that should bleed of the remaining air.

Well, it is a sealed system. Theres no radiator cap, only a cap on the resevior. I've been bleeding it for two weeks now, and still running alittle too hot. It's still not boiling, but it was 119 degress here in Arizona, and car got up to 205-210. Its like its just low on coolant, but uts not drawing any more into motor.
