When you replace an engine, the goal is a unit that matches your vehicle’s original engine, not just its size. Your VIN is the starting point, because it identifies the exact vehicle the engine has to fit.

What the VIN tells a supplier

The manufacturer, model and model year
The body style, and often the trim level and drivetrain
On many North American vehicles, the engine fitted at the factory, usually through the eighth character
The plant and serial number, which can matter when a part changed partway through a model year

What the VIN does not confirm on its own

A VIN describes the vehicle as it was built. If the engine was replaced before, the engine in the vehicle may be different. The VIN also cannot tell a supplier the condition of a used engine or which accessories came with it. That is why the engine code from your current engine and photos of its labels are still useful.

Why the same engine size is not enough

One displacement can be built in several versions within the same model line, with different fuel injection, timing systems, sensors, mounts and wiring. Swapping in the wrong version can mean extra parts, extra labour or an engine computer that does not match. Matching by VIN and engine code avoids most of these problems.

What to send

Your full 17-character VIN
The engine code from the label or block, or a photo
The engine size and fuel type
Any part numbers from the old engine or its computer
Your postal code or country, so freight can be quoted

We check this information against the unit before fulfilment and tell you if anything needs confirming. Choosing your vehicle on a website does not by itself guarantee fitment.
