REMOVAL & INSTALLATION
Tag all wires and vacuum hoses for identification to prevent confusion during installation.
- Scribe the hood hinge outline on the under-hood surface for reinstallation alignment. Have a helper support the front of the hood, remove the mounting bolts and the hood.
- Position the car under the engine lifting device. Drain the coolant into a suitable container.
- Disconnect the battery, negative cable first. Remove the battery to avoid accidental damage.
- Disconnect all hoses to the air cleaner. Remove the air cleaner assembly and mounting brackets.
- On 4-cylinder models, disconnect and remove the exhaust manifold shroud. On all engines, remove or disconnect any thermactor (air pump) parts that will interfere with the engine removal.
- Remove the upper and lower radiator hoses. Remove all drive belts.
- Unbolt and move the radiator shroud back over the water pump. If your car is equipped with an automatic transmission, disconnect the two cooler lines from the radiator tank.
- Remove the fan blades, fan spacer, pulley, radiator shroud and radiator.
- Disconnect the heater hoses from the water pump and cylinder head/block/manifold fitting. On 4-cylinder models, disconnect the heater hoses from the water pump and carburetor choke fitting.
- Disconnect the wiring to the alternator, oil pressure switch, ignition coil, temperature switch and starter motor.
The starter motor wiring might be easier to disconnect after the car has been raised up and supported on jackstands.
- Disconnect the accelerator linkage, vacuum modulator line (automatic transmission equipped models), transmission downshift rod (automatic transmission models), vacuum brake booster line, EGR valve, speed control cables and connectors (if equipped).
- Unbolt the power steering pump and air conditioner compressor with hoses connected, position out of the way and secure.
- Disconnect the flexible fuel line (from the gas tank) at the fuel pump and plug the line.
- Remove the flywheel/converter housing to engine upper mounting bolts.
On 4-cylinder engines, two 10mm X 3 / 8 in. studs are used to attach the upper housing to the engine. If the studs are removed, make sure they are reinstalled with the metric threads in the engine block.
- Raise the front of the car and safely support it with jackstands. Drain the engine oil. Drain from both oil, pan plugs, if equipped, on V8 engines.
- Disconnect the starter motor wiring, if not already disconnected. Remove the starter motor.
- Disconnect the exhaust pipe/converter from the exhaust manifold(s). Wire the pipe(s) out of the way.
- On cars equipped with manual transmissions, disconnect the clutch retracting spring. Disconnect the clutch equalizer shaft and arm bracket at the frame rail. Remove the clutch shaft and bracket.
- Remove the flywheel/converter housing lower inspection cover.
- On models equipped with automatic transmissions, disconnect the torque converter from the flywheel. It will be necessary to rotate the crankshaft to gain access to the four converter mounting nuts. Use a socket on a breaker bar or ratchet to turn the crankshaft via the crankshaft pulley center bolt. Always turn the crankshaft in a clockwise direction.
- Mark a converter mounting stud and the flywheel to insure balance alignment for reinstallation.
- Disconnect the right and left front motor mount insulators at the No. 2 crossmember. Remove the lower flywheel/converter housing-to-engine mounting bolts.
- On automatic transmission equipped models, pry the converter slightly away from the flywheel and secure the converter to the transmission with a piece of wire or small C-clamp on the housing.
- Lower the car from the jackstands. Support the front of the transmission on a piece of wood with a hydraulic jack.
- Attach a lifting sling to the engine removal brackets. Connect a chain hoist and raise the engine slightly to clear the front motor mounts.
- Carefully pull the engine forward to disengage the converter or front transmission shaft. Slowly raise the engine out of the engine compartment. Avoid bending the rear cover plate or damaging any components.
- Secure the transmission and move the car from under hoist. Lower the engine to a workbench, ground or install it on an engine stand.
- Installation is the reverse of the removal procedure. Keep the following in mind during installation. On cars equipped with automatic transmissions, start the converter pilot into the crankshaft while aligning the marks that were made previously. Make sure the studs engage the holes in the flywheel. On manual transmission equipped cars, start the transmission mainshaft into the clutch disc. While installing the engine an adjustment of the transmission position with relation to the engine may be required. Raise the transmission with the jack or lower the engine as necessary. If the converter mounting stud alignment is off, or the transmission mainshaft fails to enter the clutch disc, turn the engine in a clockwise direction (manual transmission in gear). Install the upper engine to transmission mounting bolts after the engine and transmission mate firmly together. Align the engine mounting insulators with the mount brackets, remove the jack from under the transmission and lower the engine into place.
