I had mine in and out while doing the trans cooler. Recommend that you get the dow corning silicone grease for the o rings in the pipes. Things might be a little stiff on disassembly so you may have to work the fittings a bit to loosen the crud. On reassembly check that the appropriate hoses are properly clipped into the rad shroud. The main crank pulley was a week away from cutting thru a hose that was not clipped in by someone who changed the rad before we got our 04.
