Rework Procedure
Group Number 1
1. Remove the existing ether nozzles or plugs from the left and right intake manifolds.
2. Install the components identified in Image 1.1.1. Apply thread sealant (Loctite 536) to the threads of the 423-4336 Ether Nozzles before tightening (9 +/- 2 Nm) them into the intake manifolds.
3. Check to ensure that the ether control parameter is programmed to "Enabled" by using Cat ET.

Group Number 2
1. Remove the existing ether nozzles or plugs from the left and right intake manifolds.
2. Install the components identified in Image 2.1.1 on the front right side of the engine. Apply thread sealant (Loctite 536) to the threads of the 423-4336 Ether Nozzles before tightening (9 +/- 2 Nm) it into the intake manifold.
