GM Power Steering fluid

[MaverickZ71]

I need to add some power steering fluid in my '09 Silverado CC Z71 4x4 (5.3L, 6-speed, 3.42 gears) and have always been meticulous in following the owner's manual on service intervals/GM parts.

 

Owner's manual says to use GM power steering fluid, GM Part #89021184.

 

Local GM dealer can't find that part number in their computer. They have some quarts of GM PS fluid that have been on their shelf for years (bottles all dusty) with a different GM part number and they that fluid is fluid.

 

Now, I know in the old days ATF was often substituted for PS fluid. But GM trucks have changed from recirculating ball to rack-and-pinion steering since then, so I'm thinking that's why they have different bottles/part numbers.

 

Can anyone tell me what the current correct GM part number for the proper power steering fluid is? Or an aftermarket fluid that is an acceptable substitute?

89021184 has been changed to a new part number......89021185 is the newest part number.

I don't have an idea why they didn't know that,or couldn't check on it for you.

You can also use AMSOIL's power steering fluid. It is a good choice if you want to go with 100% synthetic fluid.

Does the Amsoil PSF meet or exceed the Cold Climate fluid that GM sells?

Yes, it has a -51°F pour point.

Agree dealer probably just wanted to sell the old bottle they had to get rid of it. The system automatically updates part numbers and shows old ones as well.

I think by the follow up post to your question. That you have found out what type of service you may expect from your local GM Dealer.

2 years later and this pops up. HA

 

Yes, I totally agree.

 

The GM Mega-store dealer (Chevy/Buick/GMC) a block from where I live in the 'big city' is absolutely clueless and has a history of cheating their customers. They are part of a dealer network in 3 states, and they do tv commercials every 10 minutes, but they are rude, don't want to look anything up, and don't want to spend more than 10 seconds on anything unless they think they're gonna make a lot of money off of you. In their view, they don't want to mess with selling you GM PS fluid or wiper blades and such, as you are supposed to have your maintenance done there and pay them a few hundred $ (or more) a year that way. And when you have service done there, they have the brass to tell you to give them 100% ratings on the satisfaction surveys for the substandard work they did (didn't fix the problem and broke something else!), or not to bother to turn the survey back in to GM!

 

That's why, whenever possible, I drive over 100 miles one way to the 'small-town' Chevy dealer where my parents live. They greet us by name and genuinely seem to care about their customers and will try to look stuff up and special order it for you (since they are small they don't carry a huge stock of parts, put can pretty much get anything in a day or two). Since Rich gave me the correct GM part number, I bought some from the small dealer, who had it in stock. The 'big city' dealer wouldn't even bother to track it down in their computer.

 

My truck has had it's share of problems, so I'm grateful for this forum and my 'small-town' dealer for their assistance in keeping it going.

I know this is an old thread, but the question still keeps showing up in internet searches without a current answer for those of us that want to maintain the original spec parts, etc (at 160k miles-I see no reason to change).  The original owner's manual recommended GM part number 89021184 for power steering fluid on my 2011 Silverado VortecMax.  It was apparently replaced by GM part number 89021185.  Both have now been replaced by GM part number 19329450, which also crosses over to AC Delco part number 105074.  Both are 16 oz bottles, are mineral oil-based with a special additive, and are currently available anywhere that sells AC Delco parts.
