The cam sensor is located behind the power steering reservior. You will need a 10MM deepwell socket to take the bolts off to get to the sensor. You will need an 8MM socket to take the retaining bolt off for the sensor. Just simply pull the sensor out, then use some of the residual oil that is on the old sensor and lubricate the o-ring on the new sensor.
As for the crank sensor, it is behind the compressor for the A/C. You have to loosen, but do not remove the 3 10MM bolts that hold the A/C compressor in place. Allow the compressor to drop down (of course you will have to remove the serpentine belt too) and you can get to the crank sensor. It too takes an 8MM socket and lube the o-ring on the new sensor as you did for the cam sensor.
Hope that helps.........fresh in my memory since I just did it on a friends car a few days ago..... :Beer
