Confused by engine codes? Wrong numbers cost you time, money, and parts mismatches.
Every HOWO engine has a serial number that tells its identity—knowing how to read it means ordering the right parts, avoiding delays, and protecting ROI.
Why do HOWO engine serial numbers matter in procurement?
Misreading engine codes leads to wrong orders.
Wrong parts equal wasted shipments and angry customers.
Direct Answer
Engine serial numbers are the ID of your HOWO engine—they confirm family, model, and configuration for accurate parts sourcing.
Dive Deeper
Across WD615, D12, WP10, and WP12 engines, buyers often confuse part numbers. A single wrong digit means a radiator inlet on the wrong side or a water pump flange mismatch. Serial numbers prevent this. That’s why every reliable fleet manager teaches mechanics to photograph and record the engine plate before requesting quotes.
Where can you find the engine serial number on a HOWO engine?
Searching for the number wastes time if you don’t know the spots.
Missed plates = wrong identification.
Direct Answer
HOWO engine serial numbers are stamped on the engine block, metal ID plate, and often recorded on vehicle documents.
Dive Deeper
- Engine Block Stamp: Left or right side of the block near the cylinder head.
- Metal ID Plate: Riveted plate showing engine family (WD615/D12/WP12).
- Documents: VIN card, customs records, inspection reports.
I advise all buyers to send me both a plate photo and block stamp to cross-check before quoting. It saves weeks of delay.
How do you read a HOWO engine serial number?
Letters and digits look random—but they aren’t.
Each character tells you something vital.
Direct Answer
A HOWO engine serial number encodes engine family, displacement, emission level, and sequence number.

Sample Breakdown
Example: WD615.47-123456
- WD615 → Engine family (6-cylinder, 15L displacement).
- .47 → Power rating code (e.g., 371HP).
- 123456 → Unique sequence number.
Another: WP12.420E50-987654
- WP12 → Weichai Power 12L family.
- .420 → Horsepower rating.
- E50 → Euro V emission compliance.
- 987654 → Production sequence.
Once you understand this, you’ll never confuse a WD615 radiator with a WP12 one again.
What are the most common HOWO engine families and their identifiers?
Too many buyers guess the engine by truck model.
That mistake leads to misfits and returns.
Direct Answer
The most common HOWO engines are WD615, D12, WP10, and WP12, each with unique serial number patterns.

Engine Family Table
| Engine Family | Typical Serial Example | Common Use Case |
|---|---|---|
| WD615 | WD615.47-XXXXXX | HOWO 371 dump trucks |
| D12 | D12.420-XXXXXX | HOWO T7H heavy-duty |
| WP10 | WP10.336-XXXXXX | Regional cargo & mixers |
| WP12 | WP12.420E50-XXXXXX | Long-haul tractors, Euro V spec |
This is why I always recommend serial confirmation before quoting. Two trucks may look the same outside but run completely different engine families inside.
How can serial numbers prevent wrong parts purchases?
Guessing leads to wrong shipments.
Serial numbers guarantee fitment accuracy.
Direct Answer
By confirming the serial, buyers avoid ordering radiators, pumps, or thermostats that don’t fit their engine family.

A Kenyan fleet once ordered WP12 radiators for WD615 trucks. Result: $18,000 wasted on useless parts and 2 weeks downtime. After that, they never sent a parts list without engine serials attached. Correct identification upfront saves money, time, and trust.
What documents should include the engine serial number?
Lost track? Don’t worry.
Your paperwork holds the answer.
Direct Answer
Serial numbers are recorded on VIN cards, customs clearance papers, insurance documents, and maintenance logs.
Dive Deeper
When you prepare an RFQ, always attach:
- VIN card copy (shows engine number).
- Customs clearance scan (lists engine ID).
- Inspection report (SGS, BV include it).
This prevents mistakes at every stage—quotation, export, and delivery.
FAQ: What do buyers ask about HOWO engine serial numbers?
I get the same questions every week.
Here are the answers.
Direct Answer
FAQs cover location, decoding, matching with truck model, and export documentation.
Dive Deeper
- Where is my HOWO engine number located?
→ On the block, on the ID plate, and in documents. - Can I order parts without it?
→ Risky—always confirm first. - Do two trucks with same model share engine type?
→ Not always—serial confirms. - Is the serial number on export paperwork?
→ Yes, CO and CIQ often record it. - Can you guide me via WhatsApp with photos?
→ Yes, send me clear engine plate and I’ll decode it.
Conclusion
HOWO engine serial numbers are your key to accuracy—decode them, confirm them, and you’ll never waste money on wrong parts again.
