Note. Early build engines have 11 fastener valve covers, late built engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.

Note. On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.

The 3.5L (4V) is a V-6 engine with the following features

  1. Dual overhead camshafts
  2. Four valves per cylinder
  3. Sequential Multi-Port Fuel Injection (SFI)
  4. An aluminum lower intake manifold and a composite upper intake manifold
  5. Aluminum cylinder heads
  6. An aluminum, 60-degree V-cylinder block
  7. Timing chain driven coolant pump
  8. Variable Camshaft Timing (VCT) system
  9. The electronic ignition system with 6 ignition coils
