It has had a new cam installed not long ago, not to many warranty claims on this truck. The software and datafiles have never been upgraded. The 2004 CH-CX were the worst year. In 2005 the CXN-CHN came out with the wider frame to allow bigger radiator and after cooler. The EGR cooler problems never really went away but if you keep the screen in the lower radiator "Y" pipe clean it will really help alot.
