Q: Bank location

asked by on

Which side is bank 1 and which side is bank 2?

My car has 158888 miles.
My car has an automatic transmission.

Hello. Bank 1 is the side containing cylinder No. 1 on your engine, as you face the front of the engine, that is looking dead on at the crankshaft pulley/harmonic balancer. Cylinder No. 1 is on the left side of the engine. Bank 2 of course is the other side, that is the right side. If you have been sent "there", to Bank 1, as part of a diagnostic, or as a result of a trouble code, let us know if YourMechanic can assist you with the issue.
