I have a 2004 Pontiac Grand Prix 3.8l. The power steering is leaking and I want to change the lines. Is there a diagram that show how the lines to ran?
A diagram is not needed. Order the replacement hoses and replace one at a time. The other thing is are all the hoses leaking and are sure they are not just loose.
Are you sure it’s only the lines? Generally the first thing to leak is the rack. The lines are pretty robust, but the seals subject to mechanical wear and much less robust.
It is as simple as …ordering the lines, find the power steering pump and match up which line goes where.
