Is there a kit for repairing the OEM hydraulic fan clutch?

No, I’m not interested in an aftermarket substitute.

What is it doing that it needs repaired? Leaking, sticking, not engaging?

It is stuck engaged.

Stuck engaged is a common issue.

If you disconnect the hydraulic line going to the fan clutch and blow in compressed air, and use a long piece of wood and a hammer to tap on the clutch it can help it free up. You need over 90psi in order to disengage the clutch. Once it's unstuck it should work normally if everything else is good.

You should also verify that it isn't an electrical issue. Putting a pressure gauge on the line going to the clutch should show in excess of 90psi with engine running and not at high temps (which shouldn't happen anyway with a stuck clutch)
