1999 Freightliner chassis and Cat 330hp 7.2 ??

Actually the Caterpillar 3126 was offered in both shallow and deep pan. To my knowledge, the vast majority (and all Freightliners) have the shallow pan.

Shallow pan is easy to distinguish-- it is smooth stamped steel. The deep pan is ribbed aluminum. Most shallow pan 3126's have 19 quart capacity, deep pans 29 quarts.

If any question, call Caterpillar RV Hotline with the engine serial number:

877 777-3126.
