Coolant recovery pipe - hole formed,
2009 Cobalt 2.2L
Anyone know why this coolant recovery line includes a metal segment in the middle?
My pipe mysterious grew a hole, leaked coolant for hours (or even days) and the car started to overheat on the expressway. Found it and put in a temporary measure to close the leak. But now I need to refill the system and I'm trying to figure out why I shouldn't replace the entire line with a single rubber hose, which would cost less for a quality hose (<$5) than buying a replacement OEM part ($40).

If you're cheap, you could probably plug it up with some solder or brazing.
I don't see anything wrong with a rubber hose though. Its not like they use the metal section to wick away heat.

The metal was probably done due to a rubber hose wearing through on the other parts in the area. There should be plenty of those metal lines available used, I could look and see if I have one, i'm sure I do.
But a rubber hose would work just fine from a function point, just make sure it's not rubbing on anything.

Excellent work
Excellent investigation. Just finished fix. Used 2” high temp/high pressure tubing, and 2 hose clamps. Guided metal portion away from air intake cover. Reservoir tank now releasing pressure, sure missed hearing pressure relief when removing cap. Car not heating up to 215F+ when first starting, idling at 185F now.
Great writeup and excellent investigation! Would love to help if you ever hit another roadblock.
