I know this is an old thread but thought i'd add some info from my recent engine swap so it might help others.
2009 MKX 3.5 L water pump failed at 130K killing engine.
I bought an engine at the local salvage yard for $400 with 150K miles. came from a Taurus with the W Vin code.
I've done 5+ engine swaps but my first going thru the bottom. I had in my head that it comes out with the sub frame but no. Remove sub frame then lower engine after disconnecting the engine mounts. Sub frame is pretty simple, remove bottom of struts bolts and pull the axle shafts out. Leave struts hanging but everything else comes down as a unit.
I disconnected the power steering line from the steering box pretty easy. Get new copper crush washers. disconnect the steering shaft but don't move steering wheel after this.
Disconnect the steering cooler at the right front wheel well. disconnect the reservoir line to the pump. I used suction to empty reservoir first.
I wish i removed the intake plenum before removing engine, it comes out easy, don't forget the support bolt under the throttle body. I broke a vacuum hose connector on the back when lowering the engine. The used engine i bought had the same broken vacuum port.
The engine with the intake plenum still on is 29" high from the bottom of the pan.
The replacement engine was a 2011 and the timing chain was different then the old 2009 engine. Shouldn't have ordered the parts before getting the new engine. Plus the timing chain kit for the 2011 engine didn't have the correct tensioner for the cam chains and one guide didn't match. Seems Ford mixed and matched various parts as they saw fit. In hind sight i should have just done the water pump and re used the timing chain. timing chain kit was $400.
All told with fluids and tow and such i have $1,300 into the swap. And lots of time. Most time was messing with engine, exhaust manifold bolts and waterpump while engine was on bench. 2 days pulling engine and 2 days installing.
