11.0 VALIDATION REQUIREMENTS
11.1 GENERAL
The validation of GM Powertrain units may follow a wide variety of validation procedures.
GMPT will participate with the customer in establishing the validation procedure needed to validate
the application of the V6 Gasoline Engine into the customer vehicle.
11.2 METHODS
When required, The GM Application and the Customer Release Engineer will determine a method of
design validation from the four acceptable methods listed below.
A: Validation by Analysis: 1) Simulation of the product (or its functions) or manufacturing
process and the specified conditions using mathematical
representation (math models, algorithms, equations, etc.), in
accordance with a procedure, and documenting the results
to ensure that a particular requirement has been met.
2) The generation of conclusions through the examination of
known data to ensure that a particular requirement has been
met.
I: Validation by Inspection: Examination of the product or manufacturing process, in
accordance with a procedure, and documenting specified
physical characteristics to ensure that a particular requirement
has been met.
D: Validation by Demonstration: Exercising the product or manufacturing process under specified
conditions, in accordance with a procedure, and documenting
the results to ensure that a particular requirement has been met.
T: Validation by Test: Exercising the product or manufacturing process under specified
conditions, in accordance with a procedure, collecting
quantitative data via instrumentation and documenting the
results to ensure that a particular requirement has been met.
11.3 VALIDATION DETAILS
Inspection and testing will be required to demonstrate that each V6 Gasoline Engine application is
adequate for the duty cycle and life demanded by the end user. This will take place as part of the initial
release process, and for significant changes to either the engine, transmission or vehicle systems.
Validation Methods of each application of the V6 4.3L Gasoline Engine will be applied at minimum to
the following issues:
11.3.1 Installation Review
The installation of the engine shall be validated and verified by comparison with the engineering
drawings created by vehicle manufacturer.
11.3.2 Emissions Test
To be negotiated between GM and Customer
11.3.3 Cooling System Performance Test
Cooling Subsystem Performance Test must be approved by the GM application engineer.
11.3.4 Water Snow Inhalation Performance Test
Test shall be performed to verify water and or snow can not be ingested by the engine.
11.3.5 Design Review/ Mockup
During the design installation process of the V6 Gasoline Engine into a vehicle, the GM
Application Engineer will indicate those areas that need design validation prior to construction.
