Section 2 (2.4L Engine (Service Information)): Description
The 2.4 Liter (146 cu. in.) Tigershark in-line four cylinder engine is a single over head camshaft with mechanical lash adjusters and four valves per cylinder design. This engine is NOT free-wheeling; meaning that the pistons will contact the valves in the event of a timing chain failure.
The cylinders are numbered from front of the engine to the rear. The firing order is 1-3-4-2.
The cylinder head is designed with a variable valve actuator assembly (VVAA) that takes the place of a conventional intake camshaft assembly. The cylinder block and cylinder head are cast aluminum. The engine is mounted in the vehicle transversely.
The engine serial number is located on the rear of the cylinder block behind the oil pan. The serial number is visible with the oil pan in place. The serial number contains engine build date information.
