The MTU 396 is one of MTU's longest-serving high-speed families, with decades of variants in marine, rail, genset and submarine duty. This page decodes the designation (TB / TC / TE / SE), lists representative 8V / 12V / 16V models with their ratings, and shows which spare parts differ by configuration — the detail you need before ordering the right gasket set or overhaul kit.
Request 396 variant parts: Send full designation (e.g. 16V396TE94), serial number, part numbers, quantity and destination.
1. Designation decoder
A full 396 designation reads [cylinders]V396[duty][rating]. The duty letter tells you the application family and — critically — which cylinder-head and cooling parts you need:
| Suffix | Meaning | Typical use |
|---|---|---|
| TB | Base / early marine | Yachts, naval ships, gensets (pre-TE cooling) |
| TC | Charger / industrial & rail | Locomotives, industrial stationary duty |
| TE | Enhanced (split-circuit charge-air cooling, introduced 1989) | Fast vessels, yachts, ferries, FPBs — highest-volume duty |
| SE | Submarine (low magnetic / low-noise) | Low-noise, low-magnetic propulsion |
The trailing number (34 / 44 / 54 / 64 / 74 / 84 / 94) is the rating step; "L" = uprated, "D" = a specific sub-variant. TE introduced split-circuit charge-air cooling in 1989 — its heads and gaskets are not interchangeable with TB/TC.
2. Representative variant table (8V / 12V / 16V)
Selected models across the family with published ratings. All share the 165 × 185 mm bore and stroke; outputs differ by duty, rating step and rpm:
| Model | Duty | Power (kW) | Speed (rpm) | Primary application |
|---|---|---|---|---|
| 8V 396 TB34 | TB | 835 | 1500 | Genset / marine base |
| 8V 396 TC34 | TC | 770 | 1500 | Industrial / rail |
| 8V 396 TE64 | TE | 680 | 1600 | Fast vessel (low load) |
| 8V 396 TE94 | TE | 1120 | 2000 | Yachts / patrol craft |
| 8V 396 SE84 | SE | 600 | 1800 | Submarine |
| 12V 396 TB94 | TB | 1920 | 2100 | Naval ships |
| 12V 396 TC14 | TC | 1180 | 1800 | Locomotive |
| 12V 396 TE64 | TE | 1020 | 1600 | Ferries |
| 12V 396 TE74L | TE | 1500 | 1900 | Fast vessels (high load) |
| 12V 396 TE94 | TE | 1680 | 2000 | Yachts / authority vessels |
| 12V 396 SE84 | SE | 1000 | 1800 | Submarine |
| 16V 396 TB84 | TB | 2040 | 1940 | Naval ships |
| 16V 396 TB94 | TB | 2560 | 2100 | Naval ships (high power) |
| 16V 396 TE84 | TE | 2000 | 1900 | Fast vessels |
| 16V 396 TE94 | TE | 2240 | 2000 | Fast patrol / yachts |
| 16V 396 SE84 | SE | 1350 | 1800 | Submarine |
This is a representative sample, not the full list — the 396 family spans 6V through 16V and many rating steps. Confirm your exact model against the identification plate before ordering.
3. Which parts differ by variant
"396 parts" is not one parts list. What is shared vs specific:
| Item | Shared or specific? | Note |
|---|---|---|
| Bore × stroke | All 396 share 165 × 185 mm — wet liners are family-common in principle | Exact liner sealing rings still vary by build year / serial |
| Cylinder-head gasket set | NOT universal | TB / TC heads differ from TE (split-circuit cooling); SE heads are low-noise specific. Confirm by full designation + serial. |
| Exhaust thermocouples | Sensing layout is family-common | RFQ-verified 0005350260 / 0005353960 confirmed on a 396 in continuous duty; cross-ref to non-MTU sensor must be photo-checked. |
| Turbocharger service kit | Varies by duty | TE engines use sequential turbocharging; ZR140 / ZR170 / ZR210 service kits selected by model. |
| Injectors / nozzles | Varies by build | Fuel-system parts changed across decades of production — match by engine serial, not just "396". |
4. Part-number cross-reference (verified)
Tags: RFQ = confirmed from an inbound 396 enquiry; catalog = public 396 cross-reference seed.
| Part number | Description | 396 fitment | Source |
|---|---|---|---|
0005350260 | Exhaust gas thermocouple | 396 exhaust temp sensing | RFQ RFQ · Israel buyer |
0005353960 | Exhaust gas thermocouple | 396 exhaust temp sensing | RFQ RFQ · Israel buyer |
5600160180 | Gasket | 396 general | RFQ RFQ · Oman buyer |
5582040406 | Impeller (cooling pump) | 396 seawater pump | catalog catalog seed |
5501800016 | Oil filter element | 396 lubrication | catalog catalog seed |
5. Identify your exact 396 variant
- Full designation (e.g.
12V396TE94, not "396") - Engine serial number from the identification plate
- Existing part number marked on the old component
- Build year / rating — helps separate TB/TC vs TE heads

MTU 396 Variants FAQ
What does the suffix on an MTU 396 mean (e.g. 16V396TE94)?
The cylinder count (8V / 12V / 16V) comes first. The letter group is the duty: TB = base/early marine, TC = industrial & rail, TE = enhanced fast-vessel (split-circuit charge-air cooling), SE = submarine low-noise. The trailing number (34 / 64 / 74 / 84 / 94) is the rating step, and an "L" marks an uprated version. So 16V396TE94 = 16-cylinder, enhanced fast-vessel duty, top rating step.
Can one gasket set cover every 396 variant?
No. The TB/TC heads differ from the TE heads (the TE uses split-circuit cooling introduced in 1989), and SE heads are low-noise specific. Always confirm the full designation and serial before ordering head gaskets or overhaul sets.
Which 396 parts are safe to quote from the model alone?
Family-common items like the 165 × 185 mm bore philosophy and basic sensing layout give a starting point, but we still confirm by serial. RFQ-verified numbers on this page (0005350260, 0005353960, 5600160180) are quoted same-business-day from confirmed channels.
Can you supply for the less common 396 duty variants?
Yes, provided the number can be identified. The cylinder head, cooling, and charge-air arrangement differs by variant, so the engine designation and serial number are what decide which version of a part fits. Send the designation, the serial number, and the component you need, and we confirm availability and the documentation that comes with the part before quoting.
