Caterpillar 3176 Parts

Find the Caterpillar 3176 parts you need to keep a truck earning — cylinder heads, fuel injectors, turbochargers, head gaskets and complete rebuild kits, ready to ship same-day from Colorado. The 3176 was one of Cat's first electronically controlled on-highway inline-six diesels, and the parts it shares with later C-series engines mean part-number confusion is common. Send us the OEM, competitor, or superseded number you're holding and we'll confirm fitment before you buy.

Choosing the Right Caterpillar 3176 Parts

Heavy-duty diesel components must be matched to the exact engine and application. Before ordering from this collection, verify the part number, engine model, engine serial number, and any casting or calibration number shown on the original component.

Fitment information to have ready

  • OEM, dealer, casting, or interchange part number
  • Engine manufacturer, model, and engine serial number (ESN)
  • Truck year and model when the component is chassis-specific
  • Core details for remanufactured or exchange components
