Q: How to check for fan clutch and cooling fan failure and how do you remove and install a fan clutch and cooling fan on 2005 through 2009 Toyota Tacoma?
A: To check for fan clutch failure, look for symptoms such as continuous noisy operation, looseness, vibration, or silicone fluid or grease leaking from the clutch. For cold engine checks, rock the fan back and forth by hand to check for excessive bearing play, turn the blades by hand to ensure the fan turns freely, and visually inspect for substantial fluid or grease leakage. For hot engine checks, start the engine and allow it to warm up to its normal operating temperature, then turn off the ignition switch and turn the fan by hand to feel for resistance. To remove the fan clutch, remove the radiator support shield and fan shroud upper mounting bolts, separate any hoses and harness wires from the lower section of the fan shroud, remove the fan clutch mounting nuts, and lift the Cooling Fan Assembly and shroud from the engine compartment. To install, simply reverse the removal steps.
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.
