Showing parts for every engine. Select an engine to see only what fits.

This page lists 78 engine parts for the 2017 Freightliner Cascadia, across 27 part types, covering all 6 engine options (11.9L, 11.9L DIESEL, 12.8L L6 DIESEL Turbocharged, 14.8L L6 DIESEL Turbocharged and more). Every part shows its brand, manufacturer part number and fitment notes.

Typical signs include low oil pressure after a service, or a filter that will not spin off because the old gasket stayed on the block.

This table covers the seals on each valve stem that control oil into the guides. Typical signs include a wet housing, a drip after sitting, or fluid flung off a rotating shaft. Fix the surface the seal rides on. A new seal on a grooved shaft will leak again.

Buying Engine Parts for a 2017 Freightliner Cascadia

On this vehicle, the engine covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components.

  • Match the engine first. Every engine part here is engine-specific; each row shows which engine(s) it fits.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions

How many engine parts fit the 2017 Freightliner Cascadia?

Our catalog currently lists 78 engine parts for the 2017 Freightliner Cascadia across 27 subcategories and 15 brands, covering all 6 engine options (11.9L, 11.9L DIESEL, 12.8L L6 DIESEL Turbocharged, 14.8L L6 DIESEL Turbocharged and more). Each part is matched to the engine(s) it fits.

Do engine parts differ between 2017 Freightliner Cascadia engines?

Yes. Every engine part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of engine problems on a 2017 Freightliner Cascadia?

Common symptoms include oil spots under the vehicle, blue or white exhaust smoke, ticking from the valvetrain, or coolant mysteriously disappearing. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What oil viscosity is listed for the 2017 Freightliner Cascadia?

Oil rows on this page include SAE 10W-30 and SAE 15W-40. Confirm the engine and the weight on the filler cap before you buy — high-mileage and standard fills can differ.

What should I replace at the same time?

Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2017 Freightliner Cascadia was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2017 Freightliner Cascadia?

First match the engine — each row shows which engine(s) the part fits. Then engine hard parts are unforgiving of guesswork — confirm the casting or engine code before ordering, because one model year can hide two different blocks. The notes column carries position and trim qualifiers where they apply.
