Hey guys does anyone know the part number for the little skinny hose that is located at the end of the expansion coolant resevoir that leads to the radiator? Mine is all clogged and nasty looking. Time for a new one. Thanks

 

Any hi-temp oil res hose will work. Some have used a clear hose, so you can see the level a bit easier.

 

GM P/N 25826619 Sure is expensive though. You'll be much better off taking donbrew's advice.
