When working on an engine assembly, you should be careful enough not to ruin or misplace any component. To safely remove and install an engine assembly, just follow this step-by-step guide and take note of some tips.
What you'll need:
- Sharpie or any marking material
- Jack and jack stands
Engine assembly: Steps for removal
Step 1: Make sure that the vehicle is level and parked properly. You should be able get the hoist in and out without too much trouble. There should also be adequate lighting in the area. To avoid any mistake or confusion, it will help if you will take pictures of what's under the hood. Also see to it that the fluids are drained.
Step 2: Be careful in removing the hood. The hinges should be marked properly using a sharpie or any similar material. Don't leave behind any ding, scratch, or scrape as you slide off the hood. This should be done with a helper to help you with the lifting, among other things.
Step 3: Drain the coolant and unplug the hoses. When disconnecting the hoses, make sure that you don't break any line or assembly. If they won't come off easily, rubber hoses can be cut off and replaced. Metal connectors, however, are a bit more difficult to handle.
Step 4: Disconnect the fan. After this, the tension pulley or alternator must be loosened. Remove the belts and the radiator. Also unplug the intake air supply followed by the fuel lines.
Step 5: Disengage the power steering pump. The air-conditioning compressor must be unplugged as well. Make sure you don't touch the hoses; they shouldn't be disconnected.
Step 6: Detach the electrical wire connections to the motor. The spark plug wires don't have to be disconnected yet. After this, you can work on cutting the connection of the exhaust manifold. Also unfasten connections to the transmission.
Step 7: Lift the vehicle using a jack and support it with the stands. You have to do this to be able to crawl underneath the vehicle and remove other connections.
Step 8: Release the exhaust pipe from its connections. Follow this up with starter removal. You also have to disconnect the torque converter from the flex plate. (Note: Check the vehicle manual for components that need to be disconnected.)
Step 9: Unscrew bolts from the transmission. Before you do this, the transmission must be supported using jack stands or any similar tool. Transmission connections should be unlocked and relaxed at the cross member.
Step 10: Disconnect transmission connections to the motor. You then have to remove the motor mount connection. After this, you can now crawl out underneath the car and lower the vehicle.
Step 11: Lift up the hoist and take note of the engine leveler. The chains must be connected to the bigger bolts. Be sure to hoist slowly and to make the necessary leveler adjustments for raising the front.
Step 12: Remove the engine assembly carefully to avoid any damage through bumps or hits.

Step 13: Install the engine assembly by simply reversing the steps.
Note: Check the manual for proper removal of the distributor, adjustment of the valve, and replacement of the clutch, among other things.
