How To Remove a Car Engine

You can save a lot on car repairs and maintenance if you can trouble shoot car engine problems. Here are the steps on how to remove a car engine:

1.    Park your car where there is enough space to hoist the car engine.

2.    Remove your car hood by unbolting the hinges.

3.    Disconnect the battery cables.

4.    Completely drain the radiator fluid from your engine's cooling system. Open the radiator cap then the petcock to let the coolant completely drain out in a bucket.

5.    Remove the radiator:

  • Use pliers or a screwdriver to loosen the hose clamps to slide out the hoses. If it is difficult to loosen the clamps, cut the hoses and just replace the used hoses.
  • Unscrew the radiator fan bolts and screws.
  • Separate the shroud from the radiator and take it out.
  • Remove the radiator’s mounting bolts, careful to support the radiator as the bolts are taken out.
  • Take out the radiator.

6.    Disconnect the power steering pump

  • Loosen the power steering pump connections.
  • Pull the power steering pump and the air condition compressor away from the engine with the hoses still connected.
  • Loosen the electric wires from the motor, leaving the spark plug wires attached.

7.    Set-up to work under the car.

  • Using a floor jack, raise the car high enough for you to fit under the car.
  • Position jack stands to keep the car stable and avoid it from falling on you.
  • Slide under the car.

8.    Disconnect the exhaust system from the engine.

  • Take off the starter and exhaust pipe connectors.
  • Spray cutting oil on the rusty bolts.
  • Disconnect the exhaust pipe-to-manifold bolts connecting the motor to the transmission.

9.    Remove the carburetor, if the engine has a carburetor.

  • Take out the winged nut, at the top center of the air cleaner housing
  • Lift out the air cleaner from the carburetor.
  • Disconnect hoses attached to the housing, and the accelerator linked to the carburetor.
  • For easier reassembly, mark the hoses attached to the carburetor, like the hose for a smog emission device.
  • Loosen the metallic fuel line from the carburetor.
  • Take out the carburetor mounting bolts from the base.
  • Separate the intake manifold from the carburetor.
  • Label the wires connected to the back of the alternator.
  • Disconnect all the alternator wires, the temperature sensor and oil pressure sender electrical wire.

10.    Connect an engine lift

  • Attach the lifting chains to the corners of the engine.
  • Attach the chains to the crane's hook.
  • Lift the engine slightly to remove slack from the chains.
  • Remove the engine mounts’ bolts.
  • Slowly lift the chains until the engine moves up.
  • Disconnect wires that are attached to the engine.

11.    There are two options to remove the engine.

  • Remove the engine with the transmission attached to it and separate them outside the car.
  • Or, separate the engine from the transmission first while inside the engine compartment.

12.    Remove the transmission mount bolts under the car.

13.    Disconnect the cable of the speedometer from the transmission.

14.    Use the engine hoist, to slowly take the engine and transmission assembly out of the compartment and lower the engine on the ground. Leave the crane attached for support.

15.    Place wooden blocks to support the oil pan and transmission pan.

16.     Remove the transmission dust cover and separate the transmission from the engine.
