If I replace an engine, do I need to tell the DVLA?

The engine in my Fiat Doblo van has broken down and the local garage that I trust has told me it needs replacing. I will do this with a reconditioned unit. Obviously the replacement unit will have a different number to the old one. Do I need to inform the DVLA of the change and, if I have to send the V5 in, can I still use my van until the replacement V5 comes back? Many thanks.

Yes, you will need to inform the DVLA of the change of engine number so it is recorded. You will then be issued with a new V5C logbook. You will need to provide the DVLA with a copy of the receipt for the replacement engine.

But be very careful when buying a new or reconditioned engine. We get lots of complaints about dishonest sellers who flog worn out or substandard engines with little or no history. A trustworthy engine seller will provide a comprehensive history file for the engine and the car it originated from. The documents should show the mileage, service history and vehicle data. You should also be given a written warranty for the replacement engine, which should last from 6 to 12 months.
