I want to replace that little hose by the turbo, that everyone has a leaking problem with... . went to cumming and sell that hose , but no other hoses..... so, do i have to go to dealer to get it... and do you change the clamps with the new hose???? I know the new clamps you buy now are made in china... not like they used to be... thanks..... also want to change out the coolant lines to the left of head, that seem to go to the heater core... . are those often changed out?????? thanks for any info Andre
