For the models from 1987 or later, start the procedure with lifting the car and placing it on jackstands, and then, remove the engine under-cover. Subsequently, ease the clamps and then disconnect the air control valve hoses from the pump provided that your kind has this feature. It is necessary to remove the union nut and take off the fluid return hose from the reservoir tank then, the power steering fluid should be drained into clean container. Next unscrew the pressure line from the pump. Get to a higher degree of tension on the power steering pump drivebelt and thereafter loosen the pulley nut. Slightly unscrew the drivebelt adjuster bolt and pull the drivebelt off the engine. Subsequently, undo the mounting bolts to get the power steering pump unit out of the assembly. It is a process, where the removal steps are done opposite, making certain that all the bolts and screws are tightened just as how tight they were before and the tension of the drive belt. Last but not least, fill up the pipe to the required optimum level of the fluid and pressurize the reservoir to release the trapped gases.
