Just unscrew it and replace the wiring.
The upper oxygen sensor is on the exhaust manifold, close to the headpipe.
The replacement sensors are often plug compatible, but others must be spliced in to the old wiring. If you end up with that, refer to the instruction to figure out where the wires go.
The coolant temp sensor is located directly under the EGR valve, just in back of the upper radiator hose connection on the engine. The sensor has 2 wires and uses a 14mm socket to replace
it is the upper stream o2 sensor before the convertor
It"s located on the rear manifold, between the firewall and the engine for the upper oxygen sensor(b1s1), and between the catalyst converter and the resonator for the second oxygen sensor (b1s2), between the pipe and the floor.
the camshaft position sensor is on the left side of the engine , at back on the upper side . you have to demont the conector , than unscrew and replace it
The sensor is located under the upper rad hose Directly below the hose is a sensor with 1 wire to it That is for the gauge Just behind and down from that is a sensor with 2 wires This is the fan sensor
All oxygen sensors on all vehicles are on either the exhaust manifold or the upper end of the head-pipe.
Easy place, just hard to describe. It is located on the side of the engine, not front or back. It is located on the drivers side. A little below and back of the the upper radiator hose. (I RECOMMEND WHEN REPLACING THE SENSOR, TO ALSO REPLACE THE WIRING FOR IT TOO, GM SELLS THE NEW HARNESS FOR IT).
On the back of the engine......meaning the right side if looking at the vehicle (by the battery), The upper rad hose goes into the cyl. head. Below that in the middle of the head is a sensor with two wires going to it Unplug it and remove the sensor with a 13 mm deep socket...Install the new sensor and plug back in
the o2 sensor is located at the left side of the engine towards radiator and is the upper o2.
1 and the coolant temp sensor is located in the head under the upper rad hose
Bank 1 is the upper oxygen sensor(s) before the catalyst (catalytic converter) bank 2 is the oxygen sensor after the catalyst (catalytic converter)
The oxygen sensor is located on the upper portion of the exhaust manifold near the back bank of cylinders on your van. A special socket is required to remove it without damage. Go to the Related Link for more information.
