Engine

A modular engine is built around four modules:

• the intake module
• the cylinder head module (RH)
• the cylinder head module (LH)
• the lower engine module

While not all repairs can take advantage of the modular concept, most out-of-vehicle repairs benefit due to the reduction of necessary time and labor.

The basic engine components consist of the following:

• single overhead camshafts
• two valves per cylinder
• sequential multiport fuel injection (SFI)
• aluminum cylinder heads (6049)
• cast iron, 90-degree V-shaped cylinder block
• individual ignition coils for each spark plug
• composite-material intake manifold
• large-bore throttle body
