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 repair 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 transmission or 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 repair guide.
