2001 LS V8 Hydraulic Fan Reservoir issues

[DrCheeto]

Hey guys, my 01 LS has a new (surprise!) issue.

The hydraulic fan seems to be working fine, but fluid seems to be overflowing from the reservoir with the cap on tight.

Any suggestions?

Is the fluid foaming?
If so, you probably have a small leak on the suction side allowing air to be sucked into the pump. Otherwise, make sure the fluid isn't contaminated.

Make sure the reservoir is not over filled. Check on contamination. Pump old fluid out of reservoir and refill with new fluid.
