A used engine is often the most practical way to get a vehicle back on the road, especially when the original engine has failed and the vehicle is otherwise sound. It is also an expensive part to get wrong. This guide covers what to check before you buy one in Canada.

1. Identify your exact engine

Start with the engine code, not just the size. Two vehicles of the same model and year can have different engines, and the same engine can have different sensors, wiring or mounts depending on trim and build date. Your VIN is the best starting point; see how to find your engine code.

2. Know what you are buying

Complete engine: usually includes the intake, exhaust manifolds and some accessories. Ask exactly what is attached.
Long block: the block, crankshaft, pistons, heads and valvetrain, without most accessories.
Short block: the block and rotating assembly only.
Engine core: sold as-is for rebuilding, not as a running engine. See what is an engine core.

3. Ask about the donor vehicle

Ask for the donor vehicle details and its mileage when the supplier has them. Lower mileage does not guarantee condition, but it is useful information, and the donor VIN can confirm the engine matches yours.

4. Get the warranty terms in writing

Warranty coverage for used engines varies by supplier. Ask how long it lasts, whether it covers parts only or also labour, and what installation requirements apply. See our warranty information.

5. Plan the installation

Have a qualified mechanic install the engine. Most installs involve transferring parts from your old engine and replacing items such as the water pump, timing components, gaskets, fluids and filters. Budget for this alongside the engine itself.

6. Arrange shipping

Engines usually ship on a pallet by freight. Delivery to a business address such as your repair shop is often simpler than a home delivery. Inspect the engine and packaging when it arrives and note any damage on the delivery receipt. See how to ship an engine across Canada.

7. Used, rebuilt or remanufactured?

A used engine is the lowest-cost option, but rebuilt and remanufactured engines are worth comparing. See used vs rebuilt vs remanufactured engines.
