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:
The following procedure can be used on all vehicles. Slight variations may occur due to extra connections, etc., but the basic procedure covers all models.
- Relieve the fuel system pressure.
- If not already done, disconnect the negative battery cable.
- If equipped, remove the engine under cover.
- Matchmark the hood and hinges and remove the hood assembly. Remove the air cleaner assembly and all adjoining air intake duct work.
- Drain the engine coolant into a suitable container, then remove the radiator assembly, coolant reservoir and intercooler.
- If equipped with AWD, remove the transaxle and transfer case.
- Tag and detach the following components: accelerator cable, heater hoses, brake vacuum hose, connection for vacuum hoses, high pressure fuel line, fuel return line, oxygen sensor connection, coolant temperature gauge connection, coolant temperature sensor connector, connection for thermo switch sensor, if equipped with automatic transaxle, the connection for the idle speed control, motor position sensor connector, throttle position sensor connector, EGR temperature sensor connection (California vehicles), fuel injector connectors, power transistor connector, ignition coil connector, condenser and noise filter connector, distributor and control harness, connections for the alternator and oil pressure switch wires.
- If equipped, with A/C, remove the A/C drive belt and the compressor. Leave the A/C lines attached. Do NOT discharge the system. Wire the compressor aside.
- Remove the power steering pump and wire aside.
- Remove the exhaust manifold-to-head pipe nuts. Discard the gasket and replace with a new one during installation.
- Attach a hoist to the engine and take up the engine weight. Remove the engine mount bracket. Remove any torque control brackets (roll stoppers). Note that some engine mount pieces have arrows on them for proper assembly. Double check that all cables, hoses, harness connectors, etc., are disconnected from the engine. Lift the engine slowly from the engine compartment.
Install the engine and secure in position. The front lower mount through-bolt nut should not be tigthened until the full weight of the engine is on the mount.
- Tigthen the engine mount bolts as specified in the engine torque chart, located in this section.
- Install the exhaust pipe, power steering pump and A/C compressor.
- Checking the tags installed during removal, reconnect all electrical and vacuum connections.
- Install the transaxle to the vehicle and tighten the upper mounting bolts to 65 ft. lbs. (90 Nm). Install the starter assembly and tighten both mounting bolts to 54-65 ft. lbs. (75-90 Nm).
- Install the radiator assembly and intercooler.
- Install the air cleaner assembly. Install all control brackets, if not already done.
- Fill the engine with the proper amount of engine oil. Connect the negative battery cable.
- Refill the cooling system. Start the engine, allow it to reach normal operating temperature. Check for leaks.
- Check the ignition timing and adjust, if necessary.
- Install the hood making sure to align the matchmarks made during disassembly.
- Road test the vehicle and check all functions for proper operation.
