Scheme 72: Engine Identification
Scheme 72: Engine Identification

The vehicle identification number (VIN) is located on the left side rear of the engine block (1) and is typically a nine digit number stamped or laser-etched onto the engine at the vehicle assembly plant.

  1. The first digit identifies the division.
  2. The second digit identifies the model year.
  3. The third digit identifies the assembly plant.
  4. The fourth through ninth digits are the last six digits of the VIN.

Torque Values and/or Fastener Tightening Strategies

  1. All fasteners and threaded holes on the 4.8/5.3/6.0 liter engines utilize metric threads.
  2. Cylinder head, connecting rod, crankshaft balancer, and main bearing cap bolts now apply a torque angle strategy.
  3. Certain fasteners should not be reused. Bolts, studs, or other fasteners that must be replaced will be called out in the specific service procedure.
  4. Refer to «Fastener Tightening Specifications»(ref-180687-S32234360842005101000000) and «Thread Repair Specifications»(ref-180687-S30773923622005072800000)
