Where is the bank 1 on a Subaru engine?
The bank 1 on a Subaru engine refers to the side of the engine that contains the first set of cylinders. This is an important piece of information for understanding engine diagnostics and maintenance on Subaru vehicles.
Understanding Engine Banks
In a V-style engine, such as those found in many Subaru models, the cylinders are arranged in two separate banks, known as bank 1 and bank 2. Bank 1 is the side of the engine that contains the first set of cylinders, while bank 2 contains the second set of cylinders.
The bank numbering is typically determined by the engine's firing order, with bank 1 containing the first set of cylinders that fire in the sequence.
Locating Bank 1 on a Subaru Engine
On a Subaru engine, the bank 1 is typically located on the side of the engine that is closest to the driver's side of the vehicle. This is because Subaru engines are often configured with the first set of cylinders on the driver's side of the vehicle.
To identify the bank 1 on a Subaru engine, you can follow these steps:
- Locate the engine's cylinder numbering, which is usually stamped on the engine block or visible on a diagram.
- The first set of cylinders, typically numbered 1-4, will be on the bank 1 side of the engine.
- The second set of cylinders, typically numbered 5-8, will be on the bank 2 side of the engine.
Knowing the location of bank 1 on a Subaru engine is important for various maintenance and diagnostic tasks, such as replacing spark plugs, diagnosing engine issues, and interpreting diagnostic trouble codes.
What is Bank 2 on Subaru?
Re: Which side is "Bank 2" (knock sensor)?
. In the USA, for the six cylinder H6 engine, Bank 1 is on the passenger side, Bank 2 is the driver's side (left side as you sit in the car) If you are in front of your car, looking towards the windshield, then bank 2 is on your right. .
Which side is Bank 1 on an engine?
Bank 1 is the side of the engine that contains cylinder number one, which is always the forward-most cylinder. On most vehicles, this corresponds to the passenger side (or right side) for longitudinal engines, and the firewall side for transverse engines. However, this can vary by manufacturer, so checking the vehicle's service manual or identifying the cylinder with the forward-most spark plug is the most accurate way to be sure.

How to find bank 1
- For V-type engines (V6, V8, etc.):
- Locate the front of the engine: This is the end with the accessory drive (alternator, power steering pump, etc.).
- Find the cylinder closest to the front: The cylinder closest to the front of the engine is cylinder number one.
- Identify the bank: The side of the engine with cylinder number one is bank 1.
- For inline engines (like a 4-cylinder):
- There is only one bank, which is bank 1, located on the passenger side.
- To be certain:
- Check your vehicle's service manual, which will specify the location of cylinder one.
- Disconnect an oxygen sensor and use a diagnostic scanner to see which bank a fault code refers to.

Which side is Bank 1 on Subaru?
For most Subaru models, Bank 1 is on the driver's side of the engine when viewed from the front, and is the side with cylinder #1. In Subaru's flat-four (boxer) engine, there is only one bank, so Bank 1 refers to the side with cylinder 1.
- For V6 engines: Bank 1 is on the passenger (right) side and Bank 2 is on the driver's (left) side, according to this YouTube video.
- For Subaru's boxer engine (inline-four): There is only one bank, so Bank 1 refers to that single bank.
- To confirm: Always check the vehicle's factory service manual, as this can vary between models and engine types. The most accurate method is to find which side contains cylinder #1.
Where is the Bank 1 camshaft position sensor on a Subaru?
In this case it's on the driver's side here's your battery. Your oil dipstick. And then straight down right here this is where your cam shaft position sensor lives.
