I am not too familiar with your SL, but if those steel lines go into your washer resevoir, those lines are for the windshield washer fluid heater. The steel lines have antifreeze from the engine, hence hot engine coolant warms and heats up the windshield washer resevoir fluid. Hope that answers your doubt. Cheers!
