Ford F-150 Used Engine Guide: Codes, Years, Problems

The F-150 has been sold with more than ten different engines since 2011, and several of them look nearly identical once they're on a pallet. That's the main risk when you buy a used F-150 engine: not a bad engine, but the wrong one. A 2017 5.0L and a 2018 5.0L are both Coyote V8s, yet they aren't a drop-in swap. Two 3.5L V6s from the same year can be a non-turbo engine and an EcoBoost.

Most F-150 buying guides online are written for people shopping for a whole used truck. This one is for owners whose engine has already failed and who need the correct replacement. It covers how to identify your engine, which years and codes go together, the known problems to ask about on a donor engine, what parts don't swap across years, and what used F-150 engines cost right now.

Step 1: Find the two VIN digits that matter

Your 17-character VIN is on the driver-side dashboard (visible through the windshield), on the driver-door label and on your title and registration. For engine matching, two positions matter:

1. The 8th digit is Ford's engine code.
2. The 10th digit is the model year (B = 2011, C = 2012, D = 2013, E = 2014, F = 2015, G = 2016, H = 2017, J = 2018, K = 2019, L = 2020, M = 2021, N = 2022, P = 2023, R = 2024).

You need both. Ford reuses engine-code letters across generations, so the 8th digit on its own can point you to the wrong engine. Our general guide on how to match a used engine to your car by VIN code explains the rest of the VIN. The F-150 has a few traps of its own, covered below.

While you're at the driver door, note the build month and year printed on the label. You'll need it for the build-date splits described in Step 3.

Step 2: Match your engine code to your generation

This table uses the 8th-digit codes shown on F-150 engine listings in our inventory as of October 2026. If your truck doesn't fit neatly into a row, call with your VIN before you order.

Three patterns in that table catch people out:

• Code 8 means a non-turbo 3.5L V6 on a 2015-2017 truck, but a 3.5L EcoBoost on our 2021-2023 listings, such as this 2023 F-150 3.5L turbo engine, VIN 8. Read the 10th digit too.
• Code B was the 3.3L V6 from 2018 through 2023. On our 2024 listing, B is the 3.5L hybrid.
• Code F stayed on the 5.0L through 2017. From 2018 the V8 shows code 5. The 2018 engine gained port fuel injection alongside direct injection, so it isn't interchangeable with a 2015-2017 engine.

The 3.5L EcoBoost from 2017 to 2020 needs extra care. Ford redesigned it for 2017. It also put the high-output Raptor version in the 2019 and 2020 Limited, and in some years both versions share a VIN code. If you have a Raptor or Limited, tell your supplier the trim as well as the VIN.

Step 3: Check the build date, not just the year

Ford sometimes changes parts partway through a model year. When that happens, two trucks with the same year and code can need different engines. Our F-150 listings are split by build date wherever we've seen this happen. For example:

• 2013 5.0L: built through 01/03/13, or from 01/04/13 onward. Here's a 2013 F-150 5.0L, VIN F, built through 01/03/13.
• 2014 3.5L EcoBoost: split at 12/15/13.
• 2018 3.3L V6: built through 02/25/18, or from 02/26/18. Here's a 2018 F-150 3.3L, VIN B, built through 02/25/18.
• 2019 2.7L EcoBoost: separate listings for trucks built from 11/28/18, such as this 2019 F-150 2.7L EcoBoost built from 11/28/18.

The build month and year are printed on the driver-door label. If your truck's date is close to one of these cutoffs, say so when you order.

Step 4: Know what doesn't swap

Even when the engine family matches, some parts don't carry across years. Ford's own service documents flag several of them:

• 2.7L oil pans. Ford's TSB 19-2205 warns that 2015-2017 2.7L engines are not compatible with the later press-in-place-gasket oil pan. That pan doesn't have the PCV check valve the early engine needs, and Ford says using it will cause engine damage. If you put a 2018 or newer 2.7L oil pan on a 2015-2017 engine, or the reverse, you could ruin a good engine.
• 5.0L 2017 vs 2018. The 2018 V8 moved to port plus direct injection, so the injectors, fuel system and calibration differ.
• 3.5L non-turbo vs EcoBoost. Same displacement, but they're different engines with different intake, fueling and wiring. A non-turbo engine won't go into an EcoBoost truck or the other way around.
• Diesel and hybrid. The 3.0L Power Stroke and the 3.5L PowerBoost each need a donor of the same type. The hybrid also has its own high-voltage system.
• Transmissions. The 2.7L, 3.5L EcoBoost and 5.0L moved to Ford's 10-speed automatic by 2018, while the 3.3L kept a 6-speed. If you also need a transmission, match it separately using our used F-150 transmissions inventory.

Putting a different engine type in your truck, such as a 5.0L in a 2.7L truck, is a full engine swap, not a replacement. You'll need wiring, mounts, a calibrated PCM and sometimes a different transmission, and in California it means an inspection by a state referee. Our guide to California engine swap rules explains that process.

Step 5: Ask about each engine's known problems

Every F-150 engine has a documented weak spot. You don't need to avoid a particular engine, but you should know which records to ask for and what to listen for once it's installed.

3.5L EcoBoost, 2011-2016: timing chain and cam phasers

Ford's TSB 17-0026 covers 2011-2014 F-150 3.5L EcoBoost trucks built on or before October 10, 2014, that set code P0016 because of primary timing chain wear. A later bulletin, TSB 18-2305, covers 2011-2015 engines with a rattle lasting 2-5 seconds on a cold start after the truck has sat for 6 hours or more. The repair replaces all four camshaft phasers (VCT units) and the primary timing chain, and Ford lists it at about 9 hours of labor.

When buying a donor, ask whether that work has been done. Once the engine is installed, a cold-start rattle after an overnight soak is the warning sign.

3.5L EcoBoost, 2017-2020: cam phaser rattle

The second-generation engine had its own cold-start rattle, caused by worn VCT units. TSB 23-2143, which followed TSB 20-2315, covers 2017-2020 F-150s built on or before November 30, 2019. The fix replaces all four VCT units, at about 9.6 hours of labor. Ford also ran Customer Satisfaction Program 21B10, a PCM update for affected trucks. If you buy one of these engines, have your installer confirm your truck's PCM software is current.

5.0L V8, 2018-2020: oil consumption

TSB 19-2365 covers 2018-2020 F-150 5.0L engines that burn more than 1 quart of oil per 3,000 miles with no leaks. Ford traced it to intake vacuum during deceleration fuel shutoff. The fix is a PCM reflash, a new dipstick on trucks built on or before October 4, 2019, and an oil change. Ford also notes that oil use is normally higher in the first 10,000 miles. After installing a replacement 5.0L, make sure the truck has the updated calibration and check the oil level regularly for the first few thousand miles.

2.7L EcoBoost, 2015-2017: oil pan leaks

The early 2.7L oil pan is sealed with RTV, and TSB 19-2205 addresses leaks from that seal. As covered in Step 4, the safe fix is a pan made for the 2015-2017 engine, not a later one. When the replacement arrives, look for a wet pan rail before it goes in.

3.3L V6, 3.7L V6 and 6.2L V8

These are the simplest gas engines in the range: no turbochargers, and on the 3.3L a straightforward 6-speed pairing. They're often the cheapest way to get a base-model truck back on the road. Check the usual things: mileage, grade, and whether the engine was pulled from a running truck.

3.0L Power Stroke diesel

It was only offered for a few years, so there are fewer donors to choose from. It's a separate engine family with its own diesel emissions hardware, so pick an installer with diesel experience and expect to pay more than for a gas engine.

Step 6: What a used F-150 engine costs

Our F-150 inventory runs from about $1,600 up. These are sample prices from Grade A listings on our site in October 2026. Each range reflects condition and grade, and you'll see the exact price at checkout.

A few things stand out. The older V8s and the base V6s are the best value. Price depends on supply as much as on the engine: a 2015 2.7L costs more than a 2020 2.7L right now. Hybrid and diesel engines sit at the top of the range.

The engine is only part of the bill. Labor, fluids, a new water pump or thermostat, and gaskets add to the total. Our used engine replacement cost guide breaks those costs down, and is it worth replacing the engine in an old car? can help if your truck is older.

Step 7: Check the engine before and after it arrives

Our checklist for buying a used engine covers the general inspection. For an F-150, also:

1. Compare the engine in the listing with your 8th digit, 10th digit, build date and, for 2019-2020 3.5L EcoBoost trucks, your trim.
2. Ask for the donor mileage and grade. Our guide on how many miles is good for a used engine can help you weigh them.
3. On EcoBoost engines, check the turbo inlets and charge pipes for oil and damage, and confirm whether the turbos are included.
4. Move any parts that don't cross over (oil pan, sensors, intake parts) from your old engine only if they match the new engine's year.
5. After installation, follow our used engine break-in checklist: fresh oil and filter, coolant bleed, scan for codes, and a short drive cycle before towing.

Warranty, shipping and returns

Every engine we sell comes with a 2-year limited parts warranty on the block and internal parts, as long as a qualified technician installs it within 10 business days. Delivery to a commercial address in the lower 48 is free, and there's no core charge (shipping policy). If the engine is the wrong one or arrives damaged, see our return policy and contact us before sending anything back. For what voids coverage, read used engine warranty: what it covers and what voids it.

To see every year and size in stock, browse our used Ford F-150 engines and filter by size. For an older truck, the 2011 F-150 5.0L, VIN F and the 2015 F-150 3.5L non-turbo, VIN 8 are good examples of how each listing shows the code, mileage and grade. If anything doesn't line up with your truck, call with your VIN before you order.
