ENGINE 2.4L DOHC

DESCRIPTION
The 2.4 Liter (148 cu. in.) in-line four cylinder
engine is a double over head camshaft with hydraulic
lash adjusters and four valve per cylinder design.
The engine is free-wheeling; meaning it has provi-
sions for piston-to-valve clearance. However valve-to-
valve interference can occur, if camshafts are rotated
independently.
The cylinders are numbered from front of the
engine to the rear. The firing order is 1–3–4–2.
The engine identification number is located on the
rear of the cylinder block (Fig. 1).

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:
• Cylinder Compression Pressure Test
• Cylinder Combustion Pressure Leakage Test
• Engine Cylinder Head Gasket Failure Diagnosis
• Intake Manifold Leakage Diagnosis
• Hydraulic Lash Adjuster Noise Diagnosis
• Engine Oil Leak Inspection
