Buying Engine Parts for a 2008 International Prostar
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. Some engine parts fit every engine; others are 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 2008 International Prostar?
Our catalog currently lists 21 engine parts for the 2008 International Prostar across 5 subcategories and 7 brands, covering both the 12.4L L6 DIESEL Turbocharged and the 12.5L DIESEL. Each part is matched to the engine(s) it fits.
Do engine parts differ between 2008 International Prostar engines?
Some do. 1 part fits every engine; the other 20 are engine-specific. Each row (and the filter at the top) shows which. 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 2008 International Prostar?
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 2008 International Prostar?
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 2008 International Prostar 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 2008 International Prostar?
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.
