I purchased a used engine to replace the 2.5L engine in my 2013 Forester. The engine I pulled from the car has a power steering pump, which requires 2 idler pulleys for the serpentine belt. The replacement engine does not have a power steering pump and only has one idler pulley for the serpentine belt. The stub for the second idler pulley is cast into the timing chain cover on the old engine. Can I swap the timing chain cover from the old engine to the new engine to get the configuration I need? As near as I can tell, the brackets and everything else looks the same between the two engines. Thanks in advance.
