I see, but when reading this post I see that I clearly have a the same problems as explained here.

My fan is working, but only on idle, full speed is never achieved. A week ago I finally refilled my A/C and checked today that the fan spins a bit faster when turning on the A/C on LO. So im gonna change chage PS fluid and replace the 9 year old belt tensioner. Hopefully this will end the overheating issue and give me better steering assistanse.

Do you have the hydraulic fan system?

I have owned my WJ since new and once a year siphon and refill the PS Reservoir.

Have used the Valvoline PS Fluid which meets the chrysler spec, it is clear color.
Amsoil developed a 100% syn PS fluid which meets the chrysler spec so I have used that last few years.

The important thing is to freshen itup.

If you have never done it, get the turkey baster and siphon out the fluid and keep it in a clear jar for a few days. Take a close look at it, you will see why it is a good move to keep it fresh.

PS and brake fluid are the most neglected along with coolant changes then the drive line.

I fully understand, and I don't disagree, but I don't belive the guy that owned the jeep prior to me used ps fluid that meet the chrysler specs. So now that I know how important this really is im gonna change the fluids to clear color so I can see when it's fully flushed
