Need to find part number for coolant reservoir

[TheBobster]

I have a 2003 Yellowstone with a CAT diesel and I want to replace the coolant reservoir. I went to a nearby CAT dealer and was informed that they would need the exact part number so they could a replacement part. I've checked the Freightliner operator's and maintenance manual but it doesn't show part numbers.

Can anyone tell me where I could go to find the part number?

Thanks

I had mine replaced at a Freightliner shop west of Albuquerque, N. Mex. Mine had a pin hole and was replaced under warranty. If you call Freightliner in Gaftney, SC and give them your VIN number they can tell you exactly what the part number is.
