  Q: How to check and replace a fan and fan clutch on Toyota T100,1995 through 2004 Toyota Tacoma and 1996 through 2002 Toyota 4Runner?

  A: Inspect the Cooling Fan Assembly for cracks, particularly at the base of each blade. Replace if cracked. Check the fan clutch for leaks and wobbling blades, replacing if necessary. Spin the Cooling Fan Assembly; if it spins freely or not at all, replace the clutch. Remove the fan shroud bolts, then the lower shroud before the main one. Remove the Radiator bolts, fan clutch-to-Water Pump nuts, and lift the Cooling Fan Assembly and shroud out. To separate the fan from the clutch hub, remove the nuts. Reinstall in reverse order.

  Q: How to check and replace a fan clutch and Cooling Fan Assembly on 2003 through 2009 Toyota 4Runner?

  A: Symptoms of fan clutch failure are continuous noisy operation, looseness, vibration or silicone fluid leaking from the clutch. To check for these symptoms, rock the fan back and forth by hand to check for excessive bearing play. With the engine cold, turn the blades by hand. The fan should turn freely. Visually inspect for substantial fluid leakage from the fan clutch assembly, a deformed bi-metal spring or grease leakage from the cooling fan bearing. If any of these conditions exist, replace the fan clutch. Start the engine and allow it to warm up to its normal operating temperature. When the engine is fully warmed up, turn off the ignition switch. Turn the fan by hand. Some resistance should be felt. If the fan turns easily, replace the fan clutch. To remove the fan clutch, remove the radiator support shield and the Coolant Reservoir, then remove the fan shroud upper mounting bolts. The lower portion of the fan shroud is attached to the radiator using locating notches on each side. The fan shroud must be lifted straight up to clear the notches. Separate any hoses and harness wires from the lower section of the fan shroud. Remove the fan clutch-to-water pump pulley mounting nuts and separate the fan from the pulley. Lift the fan and shroud from the engine compartment. To separate the fan blades from the viscous clutch hub, remove the mounting bolts. Installation is the reverse of removal.
