To do so, carefully disconnect the blade from the pole and unscrew the motor from the frame. A problem experienced by some owners of the GL1800 Goldwing is overheating at slow speeds. However, you can still "reverse" the fan by simply installing it backwards. Would low freon stop the reversing... How can be the direction of rotation of an induction motor reversed apart from reversing the connections of condensor(capacitor in table fan) ? You should have a hole on the side of the radiator guard (nose piece) or the fan guard will have a section the is large enough the flip the blade. \$\begingroup\$ If, by cooling fan, you mean a typical computer case fan, those are not simple DC motors, they typically contain other electronics as well, which would not be very happy with reversed supply polarity. There's really nothing wrong with the engine running hotter than normal. Here is a point I'd like to make...just reversing the fans isn't gonna solve all the airflow issues.. Is there a way to reverse the direction WITHOUT the remote? I tested it myself just to be certain and sure enough when the leads were switched the fan spun in the opposite direction. The motor is not physically reversed. Reversing the fans requires two steps: (1) reversing the fan blade assembly on the motor, and (2) reversing the wiring in the connector so the fan motor turns the opposite way. Three washers were too tall. I found a leak in the condenser coil, in the "U" shape joint. I bougth an electric raditor fan for my Toyota FJ-40. The fan housing needs shimmed away from the radiator. Notice that the fan is located on the opposite side of the radiator hoses. A mod some people do is reverse the fans so the fan-generated airflow is always out through the sides of the fairings to match the incoming air (the two airflows work in tandem instead of fighting each other). It couldn't hurt anything. The Derale electric fan, # D18914, is a pusher or puller fan. I think a secondary thermostat switch has been pondered by a person or two. I have a real temperature guage so I can see this happening. Find the fan for your application from our search engine. By reversing the Fan Wires on the new capacitor, the fan spun clockwise and the air was blowing out of the unit. Here is the left side fan/radiator assembly off the bike. To get the full benefits of reversing the fans you have to have some way of making the fans run during this range, too. I have reversed the positve and negative wires and the fan continues in the same direction. People on the the GL1800riders forum like to argue the merits of reversing the fans. Thousands of radiator fans reviews, same day shipping. Flex-A-Lite ® Flex Fans move considerable air at idle and the blades flatten out at higher engine RPM to reduce engine drag for better performance and improved fuel economy.. Flex-A-Lite ® was founded in 1962 with the original Flex Fan concept. Update 2011: Following a rear end collision I had to rebuild the bike, so I made the cooling system even more robust by adding larger radiators from a newer bike. I bought two puller fans from spal and found that I don't have room for both so I wanted to run one as a pusher from the front of the radiator. There are two bolts holding it on and one tab it sets in. I know I don't like it...whether it's actually okay or not. Press the "Reverse" button again to revert to the previous direction of airflow. The last thing to modify is the plug. It's getting to the fans that takes time. Just because the radiator fan is not on does not mean that it is not working. Update: After having this mod for four years I can say it's a very worthwhile mod (for me). If a blade is angled down and the fan turns in the same direction as the blade angle, it will blow forward. If you can get in there, you can probably reverse the direction by flipping two of the three sensors and two of the three windings. I reinstalled the radiators, filled the bike with coolant, and let it idle until the fans kicked on. That won't be easy to do since these are all nicely integrated onto a small board. I know this isn't recommended by spal, but I figured they have to say that for liability reasons. Here is a point I'd like to make...just reversing the fans isn't gonna solve all the airflow issues.. It's getting to the fans that takes time. When the fan blade assembly is flipped it is now higher than the housing. Motor leads are not properly connected. I know I don't like it...whether it's actually okay or not. However, at speeds in the range of 15-25 mph the incoming airflow is still insufficient for good cooling. My Hampton Bay Sautern fan came without a remote. Two of the fans rotate in "heating" mode (pushing air up to the ceiling) and one rotates in "cooling" mode (pushing air to the floor). I have a real temperature guage so I can see this happening. When in a situation where the temperature starts to rise I can flip on the fans on and the temp will hold still (under extreme situations) or cause the temperature to drop. Reversed or not, your fans will still only work when the bike is going going 0-15 mph. Overheating...coolant puking...is bad. The principle is same, air is pushed through heatsink and rest is flown over VRMs as passive cooling. I bougth an electric raditor fan for my Toyota FJ-40.
