NOTE: This step may also require removal of the EGR
connection tube, as well as disconnection of the EGR
pressure differential sensor and EGR temperature sensor.
Refer to Procedure Procedure 011-025 for the EGR
connection tube. Refer to Procedure Procedure 100-002
(Engine Views) for sensor locations.
Remove the cold starting aid on engines equipped with
