its pretty straight forward, but on the passenger side of the car, you'll have to move the compressor out of the way, if you have the tools and a reclaim machine you can remove the freon and remove the compressor completely, other wise you have to kinda wire it to the shock tower to hold it out of the way while you work.ive done it in 3 hours at my shop but if your doing it at home, it may be an all day job.make sure you check the cam lobes carefully, sometime the cam and rockers may be going bad. and when you adjust them theyll fail much faster.if they look like they are wearing or damaged, youll need to replace the cam and lifters.
