On a Chevrolet Tahoe 2003 where is Bank 1 and 2 located?

On a 2003 Chevrolet Tahoe, Bank 1 and Bank 2 refer to the cylinder banks of the engine. Since the 2003 Tahoe uses a V8 engine, it has two banks of cylinders:

* Bank 1: This is the bank of cylinders closest to the passenger side of the vehicle.

* Bank 2: This is the bank of cylinders closest to the driver's side of the vehicle.

This designation is important when diagnosing engine problems, as codes often specify which bank the issue is located in. Remember this is from the perspective of sitting in the driver's seat.
