all you have to do is make sure the system is blead. There should be two bleeder valves near the fan. Then disconnect the two hoses that connect to the ac compressor (the one that is connected to the block ). Next, unclip the hoses from the fan shroud. If you can rear the bolts to take the fan off, do it. If not, worry about it later. Then (I think it's a 12 and a 14mm) disconnect the lines that run along the front, and rear up to the fire wall. You can unbolt the "pop can" at this time. Get all the hoses out. There should be some clips for the fan power. Unclip those, and fill them with greese. Then remove the condensor. Now you have room to rear down and unbolt the compressor from the engine. Been a while since I've done it on a 4th gen. But the sols got the old memory going! Hope I helped Blake!
