Here is how to change the power steering pump on a GMC Safari or Chevrolet Astro Van. Changing the power steering pump on your van is easy, but it is also messy. To replace the power steering pump in your GMC Safari or Astro Van, buy a replacement pump and borrow or rent a pulley puller from the auto parts store. From there, disconnect the hoses and let the power steering fluid drain, then remove the pulley from the front of the power steering pump so you can get to the bolts, remove the pump from the van, and replace any rubber hoses that need replacement. The fluid return hoses are rubber, and the highpressure hose is metal. Reattach the power steering hoses. Then use the pulley puller to put the pulley back on the power steering pump and reattach the drive belt. That's how to change the power steering pump on a GMC Safari or Astro Van with a 4.3 liter V6 engine.
