Power steering lines need to be replaved. How? 90 GMC Sierra 1500
\015 How do I replace the power steering lines on this truck? One looks easily accessible but the other seems to go inside the PS fill tank.\015
I'm not sure what engine you have in your truck but the chevy's are pretty staight forward in design. Out of the two hoses that you have one is a pressure line and the other is the return. Mostly on the Chevs the pressure is the one that will give you a problem. The one that you can see and is easily accessible is most likely the return line and is a hose on a barbed fitting with a hose clamp. The other is the pressure and as the name suggests the hose clamp will not hold this one so yes it has a fitting that screws into the back of the power steering resevoir. Sometimes you can get to the resevoir from underneath but most likely you will have to remove the power steering pump to get at the hose to reattach the new one. usually not as easy as it sounds as you will have to remove the pulley (press fit) with a power steering pulley remover/installer to access one of the mounting bolts behind it. Hope this helps.
