About the Subaru Outback FB25

The FB25 is Subaru's 2.5L horizontally opposed four-cylinder with a timing chain, paired with the Lineartronic CVT and full-time all-wheel drive.

Fitment notes

Outback 3.6R models use the six-cylinder EZ36. The listing covers the 2015-2019 model years, but options such as drivetrain, emissions package and trim can change the correct part within a single year. That is why we confirm every order with your VIN and the engine code before you pay.

  • Share your 17-character VIN with your quote request.
  • If possible, send a photo of the engine code on the block or the emissions label.

What is included

Used engines are typically sold as a long block or as a complete assembly with the intake and some accessories. Your quote states exactly what is attached, such as the intake manifold, exhaust manifolds, sensors, alternator or starter, so you know what to transfer from your old engine.

Before you install

Before installation, replace the oil and filter, coolant, spark plugs and thermostat, and inspect the radiator and cooling fans. Prime the oil system before first start and check for leaks during the first run.

Warranty, shipping and payment

Your written quote lists the warranty for this part, the delivery method and both payment stages. The first stage covers verification and freight coordination. The second stage covers the part and is due only after it passes warehouse inspection. Read more about our warranty, shipping and payment process.
