Assembly
NOTE :
The rod bolts should not be reused.
1. Before installing the NEW rod bolts, the threads and under the bolt head should be oiled with clean engine oil.
2. Install each bolt finger tight, then alternately tighten each bolt to assemble the cap properly.
3. Tighten the connecting rod bolts using the two step torque-turn method:• 1st Step: Tighten bolts to 25 N·m
• 2nd Step: Tighten the connecting rod bolts an
additional 90°
4. Using a feeler gauge check connecting rod side clearance. •Check axial clearance of connecting rod.

•The crankshaft main journals should be checked for
excessive wear, roundness and scoring. Limits of
roundness on any crankshaft main journals should
be held to 0.008 mm. Limits of roundness on any
crankshaft rod journals should be held to 0.005
mm. DO NOT nick crank pin or bearing fillets. Lim-
its of out of round on any crankshaft journals
should be held to 0.005 mm.
• Check the axial clearance after installation. Stan-
dard of axial clearance should be 0.07 mm. Limits
of axial clearance should be held to 0.265 mm.
• Oil Clearance of crankshaft main journal
Clean the journal and bearing.
Install the crankshaft.
Cut the plastic-gauge to the same width as
the bearing, and then put it onto the crank-
shaft journal to make it parallel with the cen-
tral line of the crankshaft.
Install the main bearing cap carefully, and tighten the bolts to the specified torque.
Remove the main bearing cap.
Measure the oil clearance with the plastic- gauge.
Standard oil clearance of crankshaft main journal
should be 0.022 mm. Limits of oil clearance of crank-
shaft main journal should be 0.058 mm.

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.
