It looks worse than it is,
behind the nearside front wheel is a rubber sheet that is held in place with plastic push clips,remove the clips and allow the sheet to fold down and just in front of you is the oil filter.Use a chain wrench on the bottom of the filter to spin it off and jiggle it around to allow you to remove it from the vehicle.
Fitting is the reverse of this.
Oh remember to wear surgical type gloves as the oil is pretty manky
hope this helps
Regards
