Hello! I am in the middle of replacing the 16363-21060 motor for the radiator fan for a 2014 C one, it's a bit tricky because the A/C radiator shares the same plastic base at the bottom that also supports the radiator for the engine. If you pull up the engine radiator, the A/C radiator also comes along. Also the A/C radiator metal tubing interferes with pulling up the assembly composed of the fan & engine radiator if you simply move the A/C radiator forward. I think two people are needed to ensure that you do not mangle any fins. I winded up taking the bumper so I could have room to maneuver. The videos I saw just do not show having to do any of this =) When you work with the A/C radiator, avoid stressing the metal tubing for the refrigerant. If something breaks or leaks it will not be easy to service that system. Just finding the ND 11 POE oil for that system will be a challenge. Anyway, my question is: By any chance does anybody know the torque for the 10mm nut that holds the fan to the motor? It looks just like the nut used to connect the copper bus bars to the NiMH batteries. It looks like 5N·m may be good?
