This publication provides general information on components and procedures which may be useful when installing or servicing an
LTG Crate Engine.
Please read this entire publication before starting work
This LTG crate engine is assembled using brand new, premium quality components. Due to the wide range of engine applications,
if you are retrofitting a previous application, you may encounter installation differences between the LTG crate engine assembly
and the previous engine. These differences may require modifications or additional components not included with the LTG engine,
including cooling, fuel, induction, electrical, and exhaust systems. Some fabrication work may be required. It is not the intent of
these specifications to replace the comprehensive and detailed service practices explained in the GM service manuals. Reference
a service manual for a 2013Cadillac ATS (LTG) or newer, for any additional information not included in this specification. For
information about warranty coverage, please contact your local GM Performance Parts dealer.
Observe all safety precautions and warnings in the service manuals when installing this LTG crate engine in any vehicle. Wear
eye protection and appropriate protective clothing. When working under or around the vehicle support it securely with jackstands.
Use only the proper tools. Exercise extreme caution when working with flammable, corrosive, and hazardous liquids and materials.
Some procedures require special equipment and skills. If you do not have the appropriate training, expertise, and tools to perform
any part of this conversion safely, this work should be done by a professional.
Legal and Emissions Information
This publication is intended to provide information about the LTG crate engine and related components. This
manual also describes procedures and modifications that may be useful during the installation of an LTG crate
engine. It is not intended to replace the comprehensive service manuals and parts catalogs which cover General
Motors engines and components. Rather, it is designed to provide supplemental information in areas of interest to
"do-it-yourself" enthusiasts and mechanics.
This publication pertains to engines and vehicles which are used off the public highways except where specifically
noted otherwise. Federal law restricts the removal of any part of a federally required emission control system on
motor vehicles. Further, many states have enacted laws which prohibit tampering with or modifying any required
emission or noise control system. Vehicles which are not operated on public highways are generally exempt from
most regulations, as are some special interest and pre-emission vehicles. The reader is strongly urged to check all
applicable local and state laws.
Many of the parts described or listed in this manual are merchandised for off-highway application only, and are
tagged with the "Special Parts Notice" reproduced here:
Special Parts Notice
This part has been specifically designed for Off-Highway application only. Since the installation of this part may
either impair your vehicle's emission control performance or be uncertified under current Motor Vehicle Safety
Standards, it should not be installed in a vehicle used on any street or highway. Additionally, any such application
could adversely affect the warranty coverage of such an on-street or highway vehicle.
The information contained in this publication is presented without any warranty. All the risk for its use is entirely assumed by the
user. Specific component design, mechanical procedures, and the qualifications of individual readers are beyond the control of the
publisher, and therefore the publisher disclaims all liability incurred in connection with the use of the information provided in this
publication.
