Ford Bronco II VIN Decoder: History, Engines and VIN Lookup Guide
Every Ford Bronco II carries a 17-character Vehicle Identification Number, and decoding it is the quickest way to confirm what a given SUV really is before you trust a listing. The VIN reveals the model year, the plant it came from, the engine fitted at the factory, the drivetrain and the safety equipment. On the Bronco II this matters most for confirming the engine and whether the vehicle is rear-wheel drive or four-wheel drive, and verifying the model year a seller claims. Run any Bronco II VIN through the decoder above to read it in seconds. The guide below explains how the number is built, walks through the model’s run, and points out what to check.

How a Ford Bronco II VIN is put together
The 17 characters follow a global standard, so each position carries fixed meaning. The Bronco II was built in the United States, and its VIN begins with 1FM, marking a Ford sport utility built in the United States. Characters four through eight describe the body, the restraint system, the drivetrain and the engine. The ninth character is a check digit, the tenth is the model year, the eleventh is the plant, and the final six are the unique build sequence.
| VIN clue | What it means |
|---|---|
| WMI 1FM | Ford Bronco II built as a Ford SUV in the United States |
| Position 9 | Check digit that validates the whole VIN |
| Position 10 | Model year code (for example E is 1984, L is 1990) |
| Positions 4 to 8 | Body, drivetrain, restraint system and engine |
| Positions 12 to 17 | Unique sequential build number |
You will find the VIN at the base of the windshield on the driver’s side, on the door jamb label, and in the registration paperwork.
Ford Bronco II VIN position by position
The Bronco II uses the seventeen character VIN from the start, so every one reads the same way. Go through it in order and you can settle the year, the plant and the engine before you rely on the seller’s word.
| Position | Name | What it tells you on a Bronco II |
|---|---|---|
| 1 to 3 | World Manufacturer Identifier | 1FM marks a Ford built in the United States as an SUV or multipurpose vehicle |
| 4 to 7 | Vehicle descriptor | Body and drive layout, where two wheel drive is separated from four wheel drive |
| 8 | Engine | The engine code, read with the year, since the range ran from the V6 to a turbodiesel |
| 9 | Check digit | A calculated character that validates the rest of the VIN |
| 10 | Model year | A single character, listed in the chart below |
| 11 | Assembly plant | The Ford factory that built the vehicle |
| 12 to 17 | Serial number | The build sequence unique to that Bronco II |

Where to find the VIN on a Ford Bronco II
Read the VIN through the base of the windshield on the driver side and check it against the label in the driver door jamb. On a small four wheel drive that has often been used off road, make sure the number is intact and matches the paperwork before you buy, since hard use and rust take their toll on these.
Reading a Bronco II VIN in practice
Take a VIN that starts with 1FM and shows H in position ten. That marks it as a United States built Ford SUV from the 1987 model year. The descriptor characters then tell you whether it is two or four wheel drive, position eight identifies the engine, and the final digits are the vehicle’s own serial number.
About the Ford Bronco II
The Bronco II was a compact SUV sold from 1984 to 1990, based on the Ranger pickup and slotting below the full-size Bronco. It offered rear-wheel drive or four-wheel drive and a compact, capable package that made it popular before the Explorer replaced it. It used the German-designed Cologne V6 family throughout its life.
| Phase | Years | Body | Key engines | VIN type |
|---|---|---|---|---|
| Ford Bronco II early | 1984 to 1986 | Compact SUV | 2.8 Cologne V6 | 1FM, 17-character |
| Ford Bronco II late | 1986 to 1990 | Compact SUV | 2.9 Cologne V6 | 1FM, 17-character |
Ford Bronco II engines and specifications
Because the engine code sits in the middle of the VIN, a check confirms the engine the SUV was built with, which matters for parts on an older vehicle.
| Configuration | Years | Power | Layout |
|---|---|---|---|
| Ford Bronco II 2.8 V6 | 1984 to 1986 | about 115 hp | Cologne V6 |
| Ford Bronco II 2.9 V6 | 1986 to 1990 | about 140 hp | Cologne V6 |
Ford Bronco II by model year

| Model year | VIN year code | Engine |
|---|---|---|
| Ford Bronco II 1984 | E | 2.8 V6 |
| Ford Bronco II 1986 | G | 2.8 then 2.9 V6 |
| Ford Bronco II 1988 | J | 2.9 V6 |
| Ford Bronco II 1989 | K | 2.9 V6 |
| Ford Bronco II 1990 | L | Final model year |
Reliability and the things worth checking
As an older compact SUV, the Bronco II’s condition matters most. Confirm a specific vehicle against records by its VIN where possible.
| Area | What to check |
|---|---|
| Ford Bronco II body and frame | Rust is the main enemy: inspect the body, floors and frame thoroughly |
| Ford Bronco II 2.9 V6 | Confirm cooling system and general maintenance, and check for overheating history |
| Ford Bronco II four-wheel drive | On 4WD models, confirm the transfer case and front axle work correctly |
| Ford Bronco II suspension | Check suspension and steering components, which wear on an off-road-capable vehicle |
A VIN check together with a careful inspection for rust and a working drivetrain is essential on a vehicle of this age.
Ford Bronco II recalls
Below are the safety recalls recorded for the Ford Bronco II by the American road safety regulator, the NHTSA. This is a reference list, not a check of your individual vehicle, and a recall applies only to certain build dates and VIN ranges. Note that the Bronco II’s well known rollover reputation was the subject of NHTSA investigations but did not lead to a rollover recall.
| Model years | NHTSA number | Area | Problem and risk |
|---|---|---|---|
| 1989 | 89V109 | Front wheel bearing | The front wheel bearing adjusting nut retaining keys may be missing, so the nut can loosen and the wheel and hub can detach from the axle, causing loss of control. Retaining keys installed where missing. |
Recall data is published by the NHTSA and changes over time, so treat this as background rather than a substitute for the official record for your VIN.
Check a specific VIN for open recalls: use the official NHTSA recalls lookup or the Ford recall page. Both are free and show whether the work has already been done.
Buying a used Ford Bronco II
Decode the VIN first and confirm the model year, engine and drivetrain match the advertisement. On these compact SUVs, a rust-free body and frame and a healthy drivetrain matter far more than cosmetics, and four-wheel-drive examples should be checked carefully for proper operation. When you are ready, enter your Ford Bronco II VIN in the decoder above to confirm the year, engine and configuration before you buy.
