Jeep Wrangler Fan Clutch Failure Symptoms

When the fan clutch starts to fail, your Wrangler will display one or more of the following symptoms:

  • The cooling fan wobbles or is excessively noisy.
  • The vehicle overheats, or the temperature gauge shows higher than normal temperatures.
  • Poor fuel economy or engine performance.

Fan Clutch Problem Diagnosis And Repair

To help with fan clutch problems, we put together this in-depth article on fan clutch troubleshooting. But in general, here’s what to look for:

  • Cooling fans either run constantly or cycle on and off once the engine reaches a specific operating temperature. The first thing to confirm is which type of fan you have on your Wrangler. Then check to see if it is operating correctly.
  • While the engine is off and cool, check to see if you can spin the fan by hand. It should move with minimal resistance and be free of wobbling or vibration.
  • Also, check the fan clutch for leaks. If you see fluid leaking from the clutch, it’s a sign it’s going bad.

Removing the fan clutch requires disconnecting the fan from the water pump, which can be done in one of two ways:

  • Older fans are connected to the water pump by four large bolts, which can be removed with a basic set of wrenches.
  • If your Wrangler has a newer-style fan, it’s probably connected to the water pump by one large center nut. You’ll either need a pulley locking tool or a way to hold the fan in place to remove the nut.
  • You may also need to remove the fan shroud and the radiator to gain access to the fan clutch. Then it’s just a matter of removing the fan and clutch assembly.
