How can I tell if my fan clutch is on the outs?
Detecting Problems While Driving Pay attention to changes in air temperature. One of the most common symptoms of a fan clutch on the outs is an inability to properly cool the air circulating through the vehicle. Listen for excessive noise when driving at high speeds.
What’s the best temperature to test a fan clutch?
Make sure your new fan clutch is the same type as the original. It’s possible to upgrade from a non-thermal clutch to a more efficient thermal model, but not the other way around. Keep your engine temperature below 210 °F (99 °C) while you’re running your tests to prevent it from overheating.
Do you need DRB to test fan Cluch?
If the connector has not come apart or damaged or if the above statement has not been exceeded then a more in depth search will be required and you will need a decent DRB to test it. Oh yeah I can stop the fan! I better order one any good suppliers out there?
What causes radial streaks in a fan clutch?
Radial streaks are another potential clue—this happens when oil escapes from the clutch and is then blown outward in all directions by the fan. Inside the fan clutch, there is a small reservoir filled with a viscous silicone-based oil. The oil flows to and from the main chamber as engine heat fluctuates, engaging and disengaging the clutch.
How do you test a fluid coupling fan clutch?
Step 1 With the engine off, inspect the fan blades carefully. Look carefully around the fan clutch for signs of oil leakage. Grab the fan assembly with your hands and move it back and forth. Try to spin the fan with your hands. Turn on the engine and let it idle. Test the fluid-coupling fan clutch visually with the engine running.

Why is my fan clutch hard to rotate?
A healthy fluid-coupling clutch should offer some resistance to fan rotation, because the silicone oil is thick and viscous. If the fan spins without resistance or is hard to rotate, replace the clutch. Turn on the engine and let it idle.
