How to Replace Engine on Ford, Mercury and Lincoln?

The procedure is similar for Ford Crown Victoria, Mercury Grand Marquis, Lincoln Town Car.          

Engine

REMOVAL & INSTALLATION is as follows.

Go through the procedure mentioned below:----

CAUTION

If the vehicle is equipped with air suspension, the electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the luggage compartment. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations. Failure to follow these instructions may result in personal injury.

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Disconnect battery negative cable from battery and properly isolate to prevent accidental reconnection.
3. Drain the engine cooling system.
4. Recover the refrigerant from the air conditioning system.
5. Relieve the fuel system pressure.
6. Drain the engine oil.
7. Remove or disconnect the following:
   
   
   Battery

   Hood

   Engine cooling fan, shroud and radiator

   Windshield wiper governor and support bracket

   Engine air cleaner outlet tube

   Engine/transmission harness connector from the retaining bracket

   Accelerator and cruise control cables at the throttle body

   Electrical connector and vacuum hose from the evaporative emission canister purge valve

   Positive battery cable from the power distribution box and harness

   Vacuum supply hose from the throttle body adapter vacuum port

   Both heater hoses

   Alternator harness from the front fender apron and the power distribution box

   Air conditioning hoses from the air conditioning compressor

   Power steering control valve harness connector

   Body ground strap from the dash panel

   Exhaust system from the exhaust manifolds and support with wire hung from the crossmember

   Retaining nut from the transmission line bracket

   3 bolts and 1 stud retaining the engine to the transmission knee braces

   Starter motor

   4 bolts retaining the power steering pump to the cylinder block and position aside
8. Transmission housing cover from the cylinder block to access the torque converter nuts.
9. Rotate the crankshaft until each of the 4 nuts is accessible and remove the nuts
10. Remove or disconnect the following:
    
    
    6 transmission-to-engine retaining bolts

    Engine support insulator (mount) through-bolts
11. Support the transmission with a floor jack and a block of wood.
    
    
    Bolt retaining the right-hand front engine support insulator to the front engine mount insulator support bracket
12. Install engine lifting bracket to the front of the left-hand cylinder head and to the rear of the right-hand cylinder head. Connect engine lifting equipment to the lifting brackets
13. Raise the engine slightly using a floor crane and carefully separate the engine from the transmission. Do not let the torque converter fall out of the transmission.
14. Carefully lift the engine out of the engine compartment and position on a workstand. Remove the engine lifting equipment.

    Fig. Top two bolts joining engine to transmission

To install:

1. Engine lifting brackets. Support the engine using a floor crane installed to the lifting equipment and remove the engine from the workstand
2. Lower the engine into the engine compartment. Start the converter pilot into the flywheel and align the paint marks on the flywheel and torque converter. Be sure the studs on the torque converter align with the holes in the flywheel.
3. Fully engage the engine to the transmission and lower onto front engine support insulators.
4. Install or connect the following:
   
   
   Engine lifting equipment and brackets

   Bolt retaining the right-hand front engine support insulator to the front engine mount insulator support bracket

   6 engine-to-transmission (bell housing) bolts and tighten to 35 ft. lbs. (48 Nm)

   Front engine support insulator through-bolts and tighten to 18 ft. lbs. (24 Nm)

   4 torque converter retaining nuts and tighten to 25 ft. lbs. (34 Nm)

   Transmission housing cover to the cylinder block

   Power steering pump on the cylinder block and the 4 retaining nuts. Tighten to 18 ft. lbs. (24 Nm).

   Starter motor

   Engine-to-transmission brace and the 3 bolts and 1 stud. Tighten the bolts and stud to 22 ft. lbs. (30 Nm).

   Transmission line bracket to the brace stud and 1 retaining nut. Tighten to 18 ft. lbs. (24Nm).

   Exhaust system to the exhaust manifolds. Tighten the 4 nuts to 18 ft. lbs. (25 Nm). Be sure the exhaust system clears the No. 3 crossmember. Adjust as necessary.

   Ground strap to the dash panel

   Air conditioning lines to the air conditioning compressor

   Alternator harness at the front fender apron and the power distribution box

   Both heater hoses

   Vacuum supply hose to the throttle body adapter vacuum port

   Positive battery cable to the power distribution box and harness

   Electrical connector and vacuum hose to the evaporative emission canister purge valve

   Accelerator and cruise control cables at the throttle body

   Engine/transmission harness connector to the retaining bracket on the power brake booster

   Windshield wiper governor and support bracket

   Fuel supply and return lines

   Radiator, cooling fan and shroud

   Engine air cleaner outlet tube

   Hood

   Battery
5. Fill the crankcase to the correct level.
6. Fill the cooling system.
7. Start the engine and allow it to reach normal operating temperature.
8. Check for leaks and proper fluid levels.
9. Evacuate and recharge the air conditioning system.
