I am looking for #20. The number on the hose has no Google results. It is 1059-2955.

The rubber is so old I can literally rub it away. I think there's a hairline crack in it, preventing my coolant from filling the radiator when it cools down (no vacuum if there's an air leak). I replaced the cap already. Problem was significantly better, but came back a year later. The coolant just sits in the overflow tank and has to be pumped back into the radiator every few days. Thanks for the help!

I replaced it with a new 3/8 heater hose.

Part number 10188032. Unfortunately, it appears that the part has been discontinued by GM.

Just go buy 3/8" heater hose for $3.00......you DO NOT need the original hose.

You'll need a clamp where the hose connects to the reservoir. You'll need to cut off the factory pressed clamp before you can swap the hose.
