How to remove engine on ford Taurus?

REMOVAL & INSTALLATION

In the process of removing the engine, you will come across a number of steps which call for the removal of a separate component or system, such as disconnect the exhaust system or remove the radiator. In most instances, a detailed removal procedure can be found elsewhere in this guide.

It is virtually impossible to list each individual wire and hose which must be disconnected, simply because so many different model and engine combinations have been manufactured. Careful observation and common sense are the best possible approaches to any repair procedure.

Removal and installation of the engine can be made easier if you follow these basic points:

If you have to drain any of the fluids, use a suitable container.

Always tag any wires or hoses and, if possible, the components they came from before disconnecting them.

Because there are so many bolts and fasteners involved, store and label the retainers from components separately in muffin pans, jars or coffee cans. This will prevent confusion during installation.

After unbolting the transaxle, always make sure it is properly supported.

If it is necessary to disconnect the air conditioning system, have this service performed by a qualified technician using a recovery/recycling station. If the system does not have to be disconnected, unbolt the compressor and set it aside.

When unbolting the engine mounts, always make sure the engine is properly supported. When removing the engine, make sure that any lifting devices are properly attached to the engine. It is recommended that if your engine is supplied with lifting hooks, your lifting apparatus be attached to them.

Lift the engine from its compartment slowly, checking that no hoses, wires or other components are still connected.

After the engine is clear of the compartment, place it on an engine stand or workbench.

After the engine has been removed, you can perform a partial or full teardown of the engine using the procedures outlined in this guide.

Except 3.4L DOHC Engines

If your vehicle is equipped with air conditioning, refer to General Information & Maintenance for information regarding the implications of servicing your A/C system yourself. Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

1. If your vehicle is equipped with A/C have the system evacuated by a qualified technician using a recovery/recycling station.
2. Disconnect the battery cables, negative cable first.

CAUTION

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

3. Drain the cooling system.
4. Mark the position of the hood on the hinges and remove the hood.
5. Disconnect the steering coupling at the pinch bolt joint inside the passenger compartment.
6. On 3.0L DOHC engines, remove the cowl extension and windshield wiper, then disconnect the main emission vacuum control connector at the two connectors located at the right hand side of the dash panel.
7. Disconnect the wiring from the Mass Air Flow (MAF) sensor, and the Intake Air Temperature (IAT) sensor.

Label all electrical connectors and vacuum hoses prior to removal so they can be reinstalled in their proper locations.

8. Remove the air cleaner outlet tube.
9. Remove the air cleaner retaining bolts at the air cleaner body.
10. Disconnect the engine intake air resonator by pushing in the top and bottom tube surfaces at the engine air cleaner and pulling the air cleaner outward. Lift the air cleaner up and out of the engine compartment.

CAUTION

Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.

11. Properly relieve the fuel system pressure.
12. Disconnect the fuel lines from the fuel injection supply manifold.

29. On 3.0L OHV engines, disconnect the retaining clips and the A/C compressor lines from the compressor. On 3.0L DOHC engines, disconnect the A/C compressor line from the heater core inlet tube. Cap all openings to prevent the entrance of dirt or moisture.
30. Raise and safely support the vehicle. Remove the front wheel and tire assemblies.
31. Remove both front stabilizer bar links from the front stabilizer bar.
32. Remove both halfshafts using the procedure in this information.
