Fan Clutch

Commence Fan Clutch replacement by unfastening the cooling fan along with shroud next remove the push-pin before liberating the electrical connector of the Fan Clutch from the shroud. First remove the Fan Clutch from its position in the fan shroud before using a socket to remove the 4 bolts from between the Fan Blade and the Fan Clutch. This step enables you to separate Fan Blade from Fan Clutch. Before installation users must apply the fastener notice from service precautions then join the Fan Blade to the Fan Clutch and fasten the 4 bolts until they reach a torque of 27 nm (20 ft. Lbs.). First, fit the Fan Clutch onto the fan shroud and then restore the push-pin connection to the Fan Clutch electrical connector and lastly replace the cooling fan and its shroud.

A replacement of the Fan Clutch begins with cooling fan shroud removal. You must first detach the push-pin before disconnecting the Fan Clutch electrical connector from the fan shroud. Disassemble the fan shroud by taking out the Fan Clutch and unfastening all Fan Blade bolts from the clutch before breaking the Fan Blade loose from the clutch. To perform the installation work start by attaching the Fan Blade to the Fan Clutch following the instructions provided in the fastener notice in service precautions. Fasten the four bolts onto the Fan Blade before torquing them up to 27 nm (20 ft. Lbs.). The first step to install the system is to reattach the Fan Clutch to the fan shroud and then connect the push-pin to the electrical connector of the Fan Clutch before reinstalling the cooling fan and shroud.

The replacement process starts by removing the cooling fan together with its shroud before detaching the Fan Clutch from the fan shroud. Remove the bolts which maintain the Fan Blade to the Fan Clutch before you can remove the Fan Blade from the Fan Clutch. The installation process starts with fan-to-fan-clutch connection while using the exact fastener that matches the required application part number at its specified placement. Repair or thread locking compound application is clearly documented as part of the service instructions for specified fasteners. Fasteners with their joint surfaces should never receive paints, lubricants or corrosion inhibitors because this will harm the fastener by altering the torque clamp force. Accurate sequence and specifications for tightening will help protect both parts and systems from damage. Fit the 4 bolts to the Fan Blade before tightening them to 27 nm (20 lb ft). Finish by joining the Fan Clutch to the fan shroud followed by putting back the cooling fan and shroud unit.

Begin by removing the cooling fan together with the shroud before detaching the Fan Clutch from the fan shroud. Separate the Fan Blade from the Fan Clutch by removing its bolts which hold the blade to the clutch. When installing the Fan Blade onto the Fan Clutch users must use the proper fastener at its correct location because replacement fasteners should match the application-specific part number. The service procedure provides requirements regarding the use of thread lock compounds and sealants for fasteners that must be replaced or use thread locking compounds during installation. Fasteners should never come into contact with paints or lubricants or any corrosion inhibitors because such additives will affect torque levels along with clamping-force capabilities which could damage the fasteners. The correct sequence along with manufacturing specifications for tightening will help avoid damage to the components. First install four Fan Blade bolts that must be torque tightened to 27 nm (20 lb ft) before fitting the Fan Clutch to the fan shroud and then reattaching the cooling fan together with its shroud.

The initial process to replace a Fan Clutch involves removing the cooling fan together with its shroud. You should start by pulling out the push-pin while disconnecting the electrical connector of the Fan Clutch from the fan shroud. The procedure demands Fan Clutch removal from the fan shroud before you can deceive the Fan Blade bolts which will divide the Fan Blade from the Fan Clutch. It is time to install the Fan Blade onto the Fan Clutch while following the fastener notice and then tighten the 4 bolts on the Fan Blade to 27 n.m (20 lb ft). After reattaching the push-pin to the Fan Clutch electrical connector users must install the Fan Clutch to the fan shroud followed by reinstallation of the cooling fan and shroud.

Take out the fan clutch from the fan shroud.
