Others will chime in too, but in my opinion, no, you do not need to change the coolant tubes. Any additional cooling capacity for the S was engineered as the result of the larger displacement engine. Since you have not changed the displacement of your engine, the factory engineering should be sufficent for your engine. The third radiator is just added peace of mind for warmer climates or prolonged idleing (like stuck in traffic day after day.)

Now when you go to upgrade your engine, then maybe....
