Radiator Hose Question

[piecesparts]

Just a thought. After you replace the radiator cap; keep an eye on the coolant level and see if it stays at the right level. If it keeps going down and when you open the radiator cap, you notice that the level seems to go have gone away misteriously---look at a possible head gasket problem. I had this once and it is a relatively common Chevy thing on their motors.
