Before taking out the power steering pump you have to turn off the car's engine starting by loosening the nut on the negative terminal of the battery. For 2.0L Zetec-E models, take off the auxiliary drivebelt and, by the power steering pump, place a container underneath, in order to catch the spilt fluid. Pull out the fluid cooler hose by using a special tool that unlock the locking tangs and by doing so, let the fluid to get out. On Ouratec models locate the pump fluid lines and the mounting bolts by turning back the front of the right fenderwell liner and then removing a single lower-headlight mounting bolt. Release the clamp and disconnect the fluid supply hose from the pump intake and put the cap on it in order to avoid accumulation of dust. Now, remove the bolt which is used to support the high pressure fluid line connected to the pump, then turn counter clockwise the union nut to disconnect the high pressure fluid line with a little dropping of fluid. If available use a basic tool to disengage a quick disconnect connection. Pull the connector away from the pressure switch by lifting its locking clip, then unbolt the pump and separate it from its housing by removing four bolts with the help of a socket-the lower bolts of the power steering pump can be accessed from beneath. Special thanks to 2.0L SPI models, the accessory drivebelt has to be removed and to do so the power steering pump pulley requires the use of a special tool or strap-wrench to hold while been removed. With the pulley still in place, you then remove the center pulley bolt followed by the pulley and then loose the power steering reservoir hose and the pressure hose so that you can drain the old fluid on to a pail. Locate the pressure hose with two wrenches, the first fitting is on the pump side and the second is on the line side and unscrew. In fact, most of the power steering pump mounting bolts are hidden under the pulley when they are in place, and so you need to pull out the pump after removing the bolts. The four pump mounting bolts can be easily accessed on 2005 and later models as long as the pulley does not have to be removed. Where the pulley is concerned, a special tool is also used to remove it and is used when installing it too. Re-installation is the process of doing the opposite of the removal, making sure that the bolts and unions are tightened to the correct torque, there is a replacement of the high-pressure outlet O-ring where necessary, the hydraulic system power steering is bled, in the case of replacement of the pump there is transfer of the power steering pressure switch and the high-pressure pipes to the new pump.
