Unbolt airbox and remove, remove power steering belt, remove p.s. jug, remove power steering pulley, then remove power steering line, remove power steering pump, unbolt a.c. compressor and slid it out of the way as far as needed with lines still attached, remove the bolts from oil filter adapter, unplug sensor from adapter and slid it out the front. Many people said the power steering pump did not need removed but I can tell you it is 100% necessary. If your cts is like mine you will need a right angle air grinder to clean the gasket off. If you are not good with cars do not attempt this job, just pay the $330.
