What type of fluid do I use in my 1998 z71 power steering pump

SOURCE: Truck won't stay running

if it is a electric fuel pump take the fuel line off carburator and get a three foot gas line hook it up to the gas line on the car run gas line into an empty gallon container and turn key on and see if you are getting a good flow of gas

check the intake gaskets. in the middle front and middle rear. If they are oily, it more than likely sucked part of the gasket in. When it warms up the leak gets bigger. The easy way to check is to get some carb cleaner and spray all around the intake while idling and warm. DO NOT SPRAY ANY EXHAUST PARTS , carb cleaner is combustible. The truck should stumble or even shut off when spraying with the carb cleaner if there is a leak.

I would suggest using Valvoline Power steering fluid.  It is certified to be used in GM vehicles.  Hope this helps.  Let me know if I can help any further.  Thanks for an honest rating and for using FixYa!

You can change the seal.But check the shaft for a tram line type grove.If this is excesive then change the pump
