2011 WK2 Power Steering

I noticed during my 42,000 mile oil change that the power steering fluid was only just above min. Should I add some? The engine was at 200-F prior to the oil change when I noticed it. Not sure how hot the PS fluid was, but it was 75-F outside.

So if I were to add fluid, can I use +4 or do I need the Mopar fluid? I assume I have the mechanical pump since it looks like the reservoir connects to a pump under the AC compressor. What does the electronic pump look like? I believe my WK2 was an October 2010 manufacture.

From WK2Jeeps.com:
Quote:
Belt pump (mechanical)
Mopar® MOPAR® Power Steering Fluid +4
p/n 05166226AA

3.6L (early build 2011 models*)
All 5.7L and 6.4L


Electric pump

Mopar® MOPAR® Hydraulic Power Steering Fluid meeting MS-11655
p/n 68065924AA

3.6L (2011.5-up model years*)

*CAUTION: There is an Electric Power Steering (EPS) pump available on later build 2011 3.6L vehicles which require a different fluid (early build 2011 3.6L vehicles have a mechanical pump). Do not mix power steering fluid types. Damage may result to the power steering pump and system if any other fluid is used. The mechanical power steering pump systems on this vehicle require the use of Power Steering Fluid +4, which meets material specification MS-9602 or equivalent. The EPS pump system uses fluid which meets material specification MS-11655 or equivalent. Do not overfill.
The next question is, why would the system lose fluid?

Since yours is an early built WK2, have a look at this TSB:

Thanks for the info, but I don't believe it applies as that TSB was for vehicles between May 20 - August 19, 2010. The MDH of mine is September 30, 2010. Lucky me.

Any info? Should I get the Chrysler fluid or get something far less expensive?

Under $8 at the dealer for Mopar PS fluid, not expensive. Make sure you get the 2011 fluid, the 2012 fluid is different (for the electric pump).

I've had the same issue with the whining noise from day one and mine is an early WK2. Thanks a lot.
