Check out the TSB - there are different power steering fluids in play for different years of WJs. The OP needs the MS 5931 spec'd fluid which isn't necessarily "plain power steering fluid". The picture of the MOPAR power steering is the correct version for his 20000 WJ.

Changed it today, found it hard to diconnect Return hose and put on a cap.

Used a pump to pull out of the tank, refilled it with fresh power steering fluid, started her up turned steering wheel left right 3-4 times,

Then i pulled out fluid and refilled, repeated this 3 times.

I got out and refilled 1QT.

He doesnt have the hydraulic fan and doesnt need the MS5931, which is actually the mopar version of plain power steering fluid. If you read the bottle alot of the newer generic fluids meet the 5931 spec anyways. So in all alot of hype about nothing. Half the dealerships will purposely put in ATF4 anyways.

This is what the factory service manual for the '02 WJ for the 4.7L says.

"CAUTION: Use MOPAR Power Steering Fluid or equivalent. Do not use automatic transmission fluid and do not overfill."

The "or equivalent" to me says that the MOPAR fluid is not a special blend or unique. I expect that any modern power steering fluid would be adequate.

I recently replaced the hydraulic fan, and I did not use MOPAR fluid. I have seen no issue relative to the new non-MOPAR fluid. In fact, the fan died when it had only seen MOPAR fluids. Lot of good that fluid did for me.

I am not a big fan of the hydraulic fan. Too complex and expensive for the purpose if you ask me. I like the KISS principle, keep it simple stupid.

It really isn't that easy to find a brake fluid that is MS5931 compatible - most brands don't list compliance with the MS5931 standard. I suspect there is a reason why MOPAR specified a standard and it doesn't really have anything to do with the hydraulic cooling system since MS5931 was specified for WJs 3years before the hydraulic cooling system was even introduced.

What is your source that says MS 5931 = "plain power steering fluid"?

He was probably getting his data from the following location.

WJ Jeeps - Power Steering Fluid - Other

It says "no exceptions" which is bogus if you ask me. The factory service manual does not say that, and that is written by Chrysler.

Thus, you need to take WJ Jeeps with a grain of salt. It is good information, but it may lead you astray once in a while.

Ditto, I see nothing wrong with resurrecting an old thread if there's new data to add

A lot of power steering fluids have a red tint to them these days so being red isn't a huge red flag. I've actually started using the royal purple steering fluid in my wj and its worked much much better than the mopar stuff....
