the oil filter is not a regular looking filter, its a cartriage type that goes into a housing, if you open the hood and look on the driverside of motor near the oil fill cap you will see a cover cap with a nut shape head on top, use a 24mm socket on a rachet and unscrew the cover,then pullfilter out, install new filter and replace oring provide with filter on the cap. hope this helps.

Testimonial: "This was great. I found it immediatly."
SOURCE: My 2006 Cadillac STS won
most of the time it occurs after replacing a battery but if this occurred out of the blue then something like the transponder has failed
you'll need a professional scan tool and about an hour to diagnose the concern
then when fixed, you'll need another 30 minutes to reprogram the computers and keys

To remove the headlight assembly you need to remove the front bumper cover. There are two bolts and one stud with a nut that hold the headlight in. Two of the fasteners are behind the bumper cover.If you remove these the headlight must come out.
