Engine, Removing
Engine, Removing
• Be sure to obtain the radio anti-theft code, because it will be necessary to disconnect the battery ground cable later in the procedure.
• The engine is removed downward together with the transmission.
• All cable ties which are opened or cut off when removing the engine, must be replaced in the same position when installing the engine.
Note the following whenever working inside the engine compartment due to limited space:
• Route all lines and wires in their original locations.
• Ensure sufficient clearance to all moving or hot components.
