As with any specific part for a complex vehicle like a heavy-duty truck, compatibility can depend on several factors:
- Specific Engine Model and Configuration: Even within the same engine models (like the D11 and D13), there can be variations based on the year of manufacture and specific configuration of the truck.
- Verification with Engine Serial Number (ESN): The most accurate way to ensure compatibility is by using the engine serial number, which provides specific details about the engine’s build and the parts used.
- Reference to Volvo’s Documentation: Volvo’s service manuals or parts catalogs can provide detailed information about which parts are appropriate for a specific engine or truck model.
- Consultation with Authorized Dealers: A Volvo authorized dealer or service center can use the ESN or other vehicle details to confirm if part number 21401712 is the right choice for a particular Volvo D11 or D13 engine.
It is crucial to make sure that the wiring harness you select is the correct one for your specific engine to avoid potential issues. Using the correct parts ensures that the engine operates as intended, maintains its efficiency, and complies with emission standards.
