A modular engine is built around four modules:
zthe intake module
z the cylinder head module (RH)
z the cylinder head module (LH)
z 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:
zsingle overhead camshafts
z two valves per cylinder
z sequential multiport fuel injection (SFI)
z aluminum cylinder heads (6049)
z cast iron, 90- degree V-shaped cylinder block
z individual ignition coils for each spark plug
