Can it be removed by itself or do you have to tear into things to get at it?

 

Must remove: Upper radiator hoses, fan shroud, water outlet, accessory belts, #2 (big) timing belt cover, power steering support
Should remove (as long as you're in there & depending on when they were last replaced): # 1 & 2 timing belt idler pulley, water pump, timing belt, fan clutch bracket.
