This PI is being revised to provide additional 2010 information, part information and warranty
information. Please discard PI0865.
The Ecotec 2.4L service engine will not have the intake manifold, high pressure fuel system or the ignition coils
installed. These components must be transferred from the original engine. A new high pressure fuel feed pipe from
the pump to the fuel rail must also be used. Do not reuse the original pipe as a fuel leak may develop.
For the 2010 model year engine, new part number 12657110, already has the correct intake camshaft and actuator
in the engine. There is no need to transfer these parts when using this part number.
Important: The new 2.4L Ecotec Service engines DO NOT come shipped with oil.
Important: For 2010-2011 models built before March 2011, check GWM to determine if the high pressure fuel pump
was ever replaced. If it was not, replace with a new high pressure fuel pump.
Parts that need to be transferred from original engine to the new service engine:
• Intake Manifold
• Fuel Injectors
• High Pressure Fuel Pump
• Fuel Feed Pipe
• Ignition Coils
