Procedure Numbering
The workshop manual procedures are numbered using the parts list numbers as a key. The first two digits oi a
workshop manual procedure number are also the parts list number (e.g. 1.5.01 Sump Removal relates to PL 1.5 Oil
Pump and Sump). Thus when carrying out a procedure, you can quickly locate the relevant parts illustration and
spare parts list.
To avoid excessive repetition, each procedure will be fully detailed once in its appropriate place in the manual. In
any other location where this procedure is required, it will be referenced only by its title and its procedure number.
Special Tools
Where special service tools are required to perform an operation, the tool number is recorded at the point of use
within the procedure. An index and illustrated list is provided in this section for the purpose of identifying special
tools.
References
References to the left, right, front or rear of the vehicle or of a component are always made as if sitting in the drivers
seat facing forward. Any such references to assemblies removed from the vehicle are to the normal orientation of
the assembly when fitted in the vehicle.
Repairs and Replacements
Where replacement parts are required, it is essential that only genuine Aston Martin parts are used. Your attention
is drawn to the following points concerning repairs and the fitting of genuine Aston Martin parts and accessories:
• Safety features embodied in the vehicle may be impaired if other than genuine Aston Martin parts are fitted.
In certain territories, legislation prohibits the fitting of parts which are not produced to the manufacturers
specification.
• Adhere to torque wrench settings given in this manual.
• Locking devices, where specified, must be fitted. If the efficiency of a locking device is impaired during
removal, it must be renewed.
• The vehicle warranty may be invalidated by the fitting of other than genuine Aston Martin parts.
