ENGINE 3.3/3.8L
DESCRIPTION
The 3.3 Liter (201 cu. in.) and 3.8 Liter (231 cu.
in.) engines are 60É V-6 engines with cast iron cylin-
der blocks and aluminum cylinder heads (Fig. 1). The
engine uses a single, block mounted camshaft with
pushrods to actuate the valves. These engines do not
have provisions for a free wheeling valve train.
The firing order is 1±2±3±4±5±6. The cylinders are
numbered from the front of the engine to the rear.
The front cylinder bank is numbered 2, 4, and 6. The
rear cylinder bank is numbered 1, 3, and 5.
The engine identification number is located on the
rear of the cylinder block just below the cylinder
head (Fig. 2).
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - ENGINE
DIAGNOSIS - INTRODUCTION
Engine diagnosis is helpful in determining the
causes of malfunctions not detected and remedied by
routine maintenance.These malfunctions may be classified as either
mechanical (e.g., a strange noise), or performance
(e.g., engine idles rough and stalls).
Refer to the Engine Mechanical and the Engine
Performance diagnostic charts, for possible causes
and corrections of malfunctions (Refer to 9 - ENGINE
- DIAGNOSIS AND TESTING - MECHANICAL)
(Refer to 9 - ENGINE - DIAGNOSIS AND TESTING
- PERFORMANCE).
For fuel system diagnosis, (Refer to 14 - FUEL
SYSTEM/FUEL DELIVERY - DIAGNOSIS AND
TESTING).
Additional tests and diagnostic procedures may be
necessary for specific engine malfunctions that can-
not be isolated with the Service Diagnosis charts.
Information concerning additional tests and diagno-
sis is provided within the following:
²Cylinder Compression Pressure Test
²Cylinder Combustion Pressure Leakage Test
²Engine Cylinder Head Gasket Failure Diagnosis
²Intake Manifold Leakage Diagnosis
²Hydraulic Lash Adjuster Noise Diagnosis
²Engine Oil Leak Inspection
