I have a 2004 2500 with the 5.7 Hemi. I just got the truck and the coolant overflow bottle has two holes in it. One for the cap and the other for a overflow tube im guessing?? I called the NAPA and the dodge dealer and no one can find the part number or even what is. The onlhy reason i found it was a overflow tube was because i found a 2004 on ebay and it had a pic of the engine. Does anyone have the part number for the replacement or know here i can get one??

 

The pic above is what i found on ebay. I need that house and plastic piece that goes into the bottle. To the right of the filler cap.
