The motor does not need to be lifted out; it does however need to be lifted up, and down to remove mounts, and then to line up the timing marks; it is a very difficult job, that rattles even the best mechanics; here the proceedure from Chrysler, although i wouldn't even attempt, unless you are sure you are up for it.
CAUTION: When aligning crankshaft and camshaft timing marks always rotate engine from crankshaft. Camshaft should not be rotated after timing belt is removed. Damage to valve components may occur. Always align timing marks before removing timing belt.
NOTE: The crankshaft sprocket TDC mark is located on the trailing edge of the sprocket tooth. Failure to align trailing edge of sprocket tooth to TDC mark on oil pump housing will cause the camshaft timing marks to be misaligned
CAUTION: If timing belt was damaged due to incorrect tracking (alignment), the belt tensioner assembly must be replaced. Refer to Timing Belt Tensioner Assembly Removal and Installation procedure in this section.
CAUTION: Ensure that the arrows on both camshaft sprockets are facing up.
NOTE: A new tensioner is held in the wound position by a pull pin.
