  Q: How to remove and install the cooling system Fan Blade on Dodge Ram 1500 Van?

  A:

  Leave the negative wire on the battery connected for now. First, pull out the air cleaner plastic intake tube, then unfasten the shroud from the bottom half and the top half. Enable the water pump hub to rotate by turning the mounting nut counterclockwise while using the Snap-On 36 MM Fan Wrench, number SP346 from Snap-On Cummins Diesel Tool Set 2017DSP and Special Tool 6958 Spanner Wrench and Adapter Pins 8346; the thermal viscous fan drive/fan blade assembly is also threaded onto the water pump hub shaft. Make sure at this point not to remove the fan blade assembly from the viscous fan drive. When the thermal viscous fan drive is removed, place it in a position so silicone fluid does not reach the bearing assembly. After that, remove the four bolts holding the fan blade assembly to the viscous fan drive. Clean the fan blades using a mix of mild soap and water; don't use any harsh scrubbing brushes. Check the assembly carefully for damaged rivets, any misshapes, bends, cracking or cracks that might be caused by broken welds and change the fan if damage is found. If you exchange the fan blade assembly because it is damaged, be sure to inspect the water pump and viscous fan drive for possible harm from too much vibration. Bolts should be tightened on the fan blade to 23 Nm torque (17 ft. lbs.) while it is connected to the viscous fan drive, followed by placing the fan blade/viscous fan drive assembly over the water pump shaft and sliding on the fan shroud and intake tube. Reconnect the negative battery cable to complete installation.

  Q: How to service and repair the radiator Fan Blade on Dodge Ram 1500 Van?

  A:

  Service and repairs can be done on the radiator fan after removing the negative battery cable. At first, take out the plastic air cleaner tube and both parts of the fan shroud. Replace the fan gear assembly by turning the mounting nut clockwise with Snap-On 36 MM Fan Wrench (SP346) and Tool 6958 spanner while preventing the pulley from rotating using Adapter Pins 8346. It is important not to try to unbolt the fan blade assembly from the viscous fan drive at this time. Be sure to stand the thermal viscous fan drive upright after removing it, so that silicone from the fan housing doesn't contaminate the roller bearing lubricant below. After that, remove the four bolts holding the fan blade assembly to the viscous fan drive. Rinse the blades with mild soap and clean water, but don't use anything that is rough on them. Look at the fan unit for cracks, bends, loose rivets or damaged welding and if you see any, change out the fan. Should the fan blade assembly need to be replaced due to damage, check the water pump and viscous fan drive for harm caused by too much vibration. Install the fan blade assembly on the viscous fan drive and tighten its bolts to 23 Nm (17 ft. lbs.); then, attach the fan blade/viscous fan drive assembly to the shaft of the water pump, fit the fan shroud and the air cleaner intake tube. Re-attach the black battery cable last.
