Why are you replacing the knock sensor that is a very uncommon part to fail?The knock sensor is under the intake manifold area screwed into the engine block sticking straight up.I don't remember what size socket it takes like i said haven't changed many bad ones.The egr valve is over by the throttle body sticking straight up the is two 10mm bolts holding it on.Again why are you changing it what codes do you have?As far as the a/c lines on the compressor if the a/c charge has been recovered by a a/c machine there 13mm bolts holding the lines on.Its real common on those cars for the low side line to pop when you charge them up because the low side runs real close to the exhaust manifold and bakes them.
