O2 Sensor Location
Standing at the front of your vehicle - the cylinders number:
LHS - 1,2,3 (front to rear)
RHS - 4,5,6
(These are the same on both SOHC and Pushrod engines)
1,2,3 should be bank 1.
O2 Sensors are mounted on the front engine pipes, not far off the gearbox. There are 2 on each pipe - both up and downstream. They appear as a bolt attached to the pipe with wires leaving.
Hope this assists.
