SUZUKI XL7 ENGINE PROBLEM

2008 Suzuki XL7 • 80,000 miles

2008 Suzuki XL7 Limited 3.6L (transverse mounted 6 cyl) AWD. Having trouble determining which manifold belongs to bank 1 and which manifold belongs to bank 2 (dual exhaust). Problem is bank 2 downstream O2 sensor. Is bank 2 located nearest to the radiator, or nearest to the fire wall?

Look at engine from crank pulley side. Left is Bank 2.

No sir. The left bank contained the forward cylinder (cylinder 1) making that bank one. The right bank closest to the radiator is bank 2.

For most vehicles, left bank is numbered 1, 3 and 5 making it bank one but for this engine, our database indicates otherwise.
