Volvo Penta Serial & Model Number Guide
Every Volvo Penta engine carries a model/serial label. Here is where to find it, what each part of the number means, and how to use it for parts, service and age.
What the number means
Worked example — TAD722GE:
| Part | Meaning | Detail |
|---|---|---|
T | Turbocharger | Present = turbocharged. |
A | Charge air cooling | A = air-to-air charge air cooler (CAC); W = water-to-air CAC instead (e.g. TWD engines). |
D | Fuel | D = diesel engine. |
722 | Engine size / series | Series/size index — roughly tracks displacement class within a family (e.g. the 520/620/720 series spans ~5.2-7.4 L); not a literal displacement figure. |
G | Application | G = generating-set engine; marine engines instead carry V (stationary and mobile industrial use). |
E | Emissions certification | E = emissions-certified variant of the base engine. |
Using the serial number
The type designation (e.g. TAD722GE) identifies the engine family and application; the engine plate's serial number identifies the individual unit for parts and service records. Volvo Penta does not publish a serial-to-build-date formula in its own engine identification material — quote the model/specification number and serial together when ordering parts or requesting service history.
Common Volvo Penta maintenance parts
The service parts Volvo Penta's own documents list across more than one engine model. Confirm the number for your unit on its model page or data plate before ordering.
