How do you take Nissan 2.5 engine out?

Actually it's not a very hard task. Disconnect everything and mark everything....all of the electrical connectors at BOTH ends. When you remove fuel lines or vacuum lines, plug them and mark them as to where they go and what they are. There are three motor mounts, One on the right side of the engine compartment, one on the left side and one in the middle. Disconnect the exhaust system. Jack the vehicle up and remove the front wheels, disconnect the struts, wheel hubs ball joints and remove the drive axles. The vehicle can then be jacked up and the engine will come down through the bottom of the "frame". If you get yourself a Haynes Repair Manual at AutoZone for the vehicle,,,,the entire procedure is there.
