I have a 2005 GMC pkup,4.8 liter, and need to add some pwr.steering fluid to the pump.
Gm says to use their fluid (part # 89021184). Is their a equivalent off the shelf at any auto store?
Thanks

 

With older vehichles you could always use automatic transmission fluid in the power steering unit. I don't know if you can still do that with the newer vehichles. I would think that any power steering fluid [available at all auto parts stores] would be fine. You might want to double check with one of the parts men at the counter.

 

I tried to get a generic fluid at two auto parts stores,and they couldn't cross reference the #
i gave them. I'm finding out that you just can't put anything in the pwr.steering units anymore. That seems to hold true for tranny fluid to.
'I bit the bullet' and picked up a quart at a GM dealer.
Thanks for your reply

 

this is just me, but on a 2005 vehicle, i would question why i would need to add
the fluid in the first place. maybe time to check for leaks while the truck is still under warranty. unless you have been driving the thing like they do on the commercials, on a truck of this age,as long as you have been keeping up with your maintenance logs, justs wants me to say hmmmm.

The truck is in perfect shape. I'm one of those that likes tom get stuff like that on hand "just in case". Actually,all this came about when i needed to get some pwr.steeing fluid for my daughter's car so i did a inventory of vehicle fluids i already had and found i didn't have anything for the truck.

We have GM,Ford,Honda, and Toyota in the family.
Quite a education on what vehicle takes what.
