My power steering cooling line is rusted & has a small drip. I went to the part on 1990 Buick Century

store to purchase a new ling & could not find one< they suggested a clamp on hose. Could I use a 3/8 copper line instead of the steel line? This line is located between the radiator & engine & clamped on the frame.

no, dont do this. go to the dealer parts and get the correct one. too much pressure for just a clamp.
