Notation on motor mount.just replaced mine on Monday. Oil filter assembly removal is not necessary, remove filter only, then unbolt drives side motor mount from chassis and lift engine up about an inch.
others that have removed the oil cooler assembly have had headaches getting it properly sealed to the block. Engine mount is the way to go.
Rear-most is bolt and nut, 14mm both sides.
Front is deceiving, from underneath you will see what looks like a nut, but it’s actually a captured welded to mount bolt, also it is 15mm.... so no need to fiddle there, just release the bolt from the top.
