Description
The 2.4L in-line four cylinder engine has the following features:
•Single overhead camshaft
• Four valves per chamber cylinder head design
• Aluminum cylinder head
• Cast iron cylinder block
Operation
The 2.4L engine utilizes 4 valves-per-cylinder and a single-overhead-camshaft design. The engine uses an individual
coil ignition system and multi-point sequential injection. The cylinder block is made of cast iron and the bearing caps
are integrated into the lower cylinder block assembly. A cast iron oil pan is located at the bottom of the lower cylinder
block. The camshaft is mounted in the cylinder head and acts against the valve tappets to open and close the valves.
The camshaft is driven off the front of the cylinder head by the timing belt. The belt is driven by a sprocket that is
located on the crankshaft. The piston assembly is an aluminum piston with a cast iron connecting rod.
The aluminum cylinder head contains a single overhead camshaft with 4 valves-per-cylinder construction. The valves
are arranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cyl-
inder head is sealed to the block using a multi-layer steel head gasket and retaining bolts.

Hydraulic Adjusters
CAUTION:
The hydraulic adjusters are a precision part. There should not be any dust or foreign matter on its
surface. Do not disassemble the hydraulic adjusters. It is required to use clean diesel oil to clean
the hydraulic adjusters.
•Soak the hydraulic adjusters in clean diesel oil.
• Using special tool MD-998442 (1) and MD-998441 (2), press the steel ball on the inside of the hydraulic
adjuster and remove all air by moving the plunger
up and down 4-5 times.
NOTE :
Use the special tool and check whether the plunger can
be pressed. If it is hard to press the plunger, the
hydraulic adjuster is normal. If it is easy to press the
plunger, repeat the previous procedure and then check
the hydraulic adjuster again. If the plunger is still loose,
the hydraulic adjuster should be replaced.
CAUTION:
After the hydraulic adjuster has been prepared, it should be kept erect to avoid the loss of diesel
oil.
