I'm new and am looking for a "how to" on pulling the 4 banger out of my father in-laws ranger.... I'm just doing a straight replacemnet with a junkyard motor.
It is smart to mark the electrical connections but the newer vehicles have unique plugs for each connection. A direct swap is pretty straight forward. Unplug everything you can find, you will need a fuel line disconnect tool, some basic hand tools and of course something to lift the engine out. A transmission jack is helpul but not required a floor jack will work too. Pull the starter so it doesn't get damaged. If it is an auto you will have to unbolt the torque converter from the flywheel; don't take the converter out. You might have to swap a few sensors and such to the junkyard engine. Make it look like the one that was in there and install in the reverse procedure. Really it isn't bad. On some jobs like pan gaskets and such I prefer to pull the engine. I change about 5-6 engines a year for people.
It's true about the electrical connectors. It's almost impossible to mis-wire a modern engine.
I like to label them with their approximate location, though "by throttle body", "left bank"... things like that. It just makes finding the mating half of the connector a lot faster.
And vacuum lines are another thing that will save you a TON of time if you label them well. You CAN figure it all out from scratch, but it'll take you ten times as long (if not more) to get it all back together correctly.
I use to get out the old Polaroid and take pictures of each side before I pulled out the engine. Digital works even better. Use baggies for small parts and fasteners with tag inside for ID.
