POWER STEERING PUMP (2.0L/2.4L ENGINE)
NOTE: This vehicle is equipped with more than one type of power steering pump. The type of power steering pump used depends on what type of power steering system the vehicle is equipped with. The standard steering system uses a constant flow rate power steering pump. The variable-assist power steering system uses a variable flow rate power steering pump. The external difference between the two power steering pumps is the type of fitting used on the power steering fluid pressure hose connection to the power steering pump. The constant flow rate power steering pump uses a standard tube nut fitting at the power steering pump. The variable flow rate power steering pump uses a banjo type fitting at the power steering pump. The removal and installation procedures for both power steering pumps though is the same.
WARNING: POWER STEERING FLUID, ENGINE COMPONENTS AND EXHAUST SYSTEM MAY BE EXTREMELY HOT IF ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES, OR ALLOW HOSES TO TOUCH HOT EXHAUST MANIFOLD OR CATALYST.
