hello all, is there a sketch of the motor to know how to install oxygen senser for a 1996 ,3.0,caravan. my mechanic told me its a bank one, im not sure which one is it,is there a different name for bank one or its location .if there is a sketch around that should be helpful.thanks

O2 Sensors on these vans are normally refered to as the upstream and downstream sensor. I believe Bank 1 is refering to the upstream sensor but I would verify with your mechanic. If the 3.0 is like the 3.3 and 3.8 engines, the upstream sensor sits on top of the exhaust manifold behind the engine.

The Free Online manuals also has a picture and instructions for changing upstream and downstream sensors.
