TORQUE SPECIFICATIONS
The 2.0L and 2.3L engines are 4 valve-per-cylinder, dual overhead camshaft engines. The engines use a coil-on-plug ignition system. The cylinder blocks are made of aluminum and the bearing caps are integrated into the ladder assemblies. An aluminum oil pan bolts to the bottom of the lower cylinder block and to the transmission to provide greater strength. The camshafts are mounted in the cylinder heads and act against valve tappets to open and close the valves. The camshafts are driven off the front of the cylinder head by one timing chain. The chain is driven by a sprocket that is located on the crankshaft. The piston assembly is an aluminum piston with a powdered metal cast iron connecting rod. The oil pump is driven by the crankshaft via a dedicated chain that is driven by the same sprocket that drives the timing chain.
