That’s how you take an engine out. It shouldn’t take you too long. Shouldn't take any more than 2 hours with one person and normal hand tools.
Also, there are a few more steps that you'll have to do before you can drop the new engine in.
1. Clean everything that you can’t get at when the engine is in the car and also paint anything that needs to be painted.
2. Unplug the wiring harness from the MAP sensor and purge control solenoid.
3. Remove the MAP sensor and purge control solenoid assembly from the firewall. You will not be needing these with the new engine, so you can just get rid of them.
4. Unbolt and unplug the resistor from the left rear of the engine bay(if equipped). You can also get rid of this because you won’t be using it on the new engine.
