EGR Tune-Up, 2010 Cascadia

[martinef1963]

Hey, good day to all.

First wanted to thank Rawze for this forum and sharing the EGR knowledge. Today I started on some of the EGR Tune-Up steps he teaches.

I was real hesitant, but man was it easy - at least these few basic steps. Removed and cleaned out the mixer pipe, venturi and exhaust gas crossover tube / lifting eye - they had plenty of soot. Used a long cylinder brush that I purchased at Lowe's and plenty of carb / choke cleaner.

Also removed and replaced the IMAP / CAC Sensor. I removed the Delta P Sensor and cleaned it off. I purchased a new one, but it is a modified / updated version that Freightliner sold me and I would have to cut three wires, crimp them and then "calibrate" the sensor.

I didn't feel that brave today and think i might just go and pay for the dealer to do this task. Cutting an electrical harness on these over engineered, sensor ridden platforms just keeps me in check.

Unless, someone, can pass on experience on this upgrade. I also replaced the o-ring from the mixer pipe, new hose that connects the mixer pipe with the venturi, gasket that connects the venturi to the exhaust gas crossover tube, etc...

I wanted to take off some other stuff, but reminded myself I am on the road, away from home and have to work tomorrow, baby steps. More to come - thanks Rawze for the knowledge.:big_smile2::big_smile2::big_smile2:
