Do wiper & washer parts differ between 2021 Freightliner M2 engines?
Yes. Every wiper & washer 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 wiper & washer problems on a 2021 Freightliner M2?
Common symptoms include chattering or streaking blades, wipers that park mid-screen, or a washer pump that hums without spraying. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
Are the driver-side and passenger-side wiper blades the same length on the 2021 Freightliner M2?
On most vehicles they differ. Check both lengths in the notes — Front Left and Front Right — rather than assuming a matching pair.
What should I replace at the same time?
Where labor overlaps, refill the washer fluid and inspect the spray nozzles with any pump replacement — blocked nozzles mimic dead pumps.
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 2021 Freightliner M2 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 2021 Freightliner M2?
First match the engine — each row shows which engine(s) the part fits. Then blade fitment differs between driver and passenger side on most vehicles — check both lengths rather than assuming a pair. The notes column carries position and trim qualifiers where they apply.
