The easy one is in the front exhaust manifold sticking out toward the radiator and is a five minute job. It looks kinda like a spark plug with two wires coming out of it. The other one is in the rear exhaust manifold and is a bear to get to. You can NOT do it laying on your back under the engine unless you have 4 foot long arms that are skinny as a four year olds. I had to pay a mech. $75.00 to put mine up on a lift to get to the rear one. Two more important notes. Your van probably has a California emmision engine. Look for and read the label stuck to hood. The California O2 sensor is about $100.00 more than the non California one. OUCH!! The electric plugs are different on the two types of sensors and are not interchangeable. Good Luck
