Engine—Service

This section covers various engine tests, adjustments, service procedures and cleaning and inspection procedures.

For engine removal, disassembly, assembly, installation, adjustment procedures and specifications, refer to Section 03-01A (2.3L) or Section 03-01B (5.0L).

These engines incorporate a closed-type positive crankcase ventilation (PCV) system and exhaust emission control system. All engine/emission control systems are covered in the Powertrain Control/Emissions Diagnosis Manual.

To maintain the required exhaust emission levels, the fuel system, ignition system and engine must be kept in good operating condition and meet recommended adjustment specifications.

When performing tests, adjustment or service to the engine fuel system or ignition system, it is essential to follow the procedures and specifications in the appropriate service group in this manual, and in the Powertrain Control/Emissions Diagnosis Manual.

Before replacing damaged or worn engine components such as the crankshaft, cylinder heads, valve guides, valves, camshafts or cylinder block, ensure that part(s) is not serviceable.

 WARNING: TO AVOID THE POSSIBILITY OF PERSONAL INJURY OR DAMAGE TO THE VEHICLE, DO NOT OPERATE THE ENGINE WITH THE HOOD OPEN UNTIL THE FAN HAS FIRST BEEN EXAMINED FOR POSSIBLE CRACKS AND SEPARATION.
