Flex-A-Lite ® was founded in 1962 with the original Flex Fan concept. Reverse fan on that and you can see how much effect might be. Reverse Rotation. Reversing polarity on spal radiator fan? I think a secondary thermostat switch has been pondered by a person or two. That said, I think there is an unsettling feeling about seeing the temperature guage going up and up towards the red. No directions came with it. If reassembled now it would hit the radiator. A shaded pole motor can be reversed by flipping the frame 180 degrees. Reverse airflow, cleaning radiator Zero airflow, neutral position Adjustabel airflow, cooling engine Reversible Cooling Fans for Radiator Cleaning Many modern industrial and agricultural machines including excavators, wheelloaders, bulldozers and tractors use multiple radiators and have a huge need for cooling air. I had my bike taken apart for other reasons so I decided to do the mod. A problem experienced by some owners of the GL1800 Goldwing is overheating at slow speeds. The direction a fan blows air is always determined by (A) the shape of the blades (sometimes called propellers) and (B) the direction they turn. We field a lot of cooling questions in our workday. Here is a point I'd like to make...just reversing the fans isn't gonna solve all the airflow issues.. Looking to install Flexxaire on your machine or integrate a Flexxaire cooling fan into a new design? The motor is not physically reversed. "What should I do to reverse the direction of the fan? Press the "Reverse" button again to revert to the previous direction of airflow. No directions came with it. I have reversed the positve and negative wires and the fan continues in the same direction. Overheating...coolant puking...is bad. I tested the setup to make sure it worked and that someone hadn't already reversed it. I know this isn't recommended by spal, but I figured they have to say that for liability reasons. I have a real temperature guage so I can see this happening. I want it to "Push" rather than pull as I can only mount the fan in front of the radiator. More than a reversing fan, the Flexxaire Fan System is the world’s leading smart airflow system, specifically designed for the heavy machinery equipment. Overheating...coolant puking...is bad. Switch the motor leads on terminals #7 & #8. If I reverse the fans in winter I will have a nice cab heater. ". Supplying negative power won't work, just fry the electronics. The fan housing needs shimmed away from the radiator. A fan in the engine bay behind the radiator should pull the air through the radiator/cooler. The Derale electric fan, # D18914, is a pusher or puller fan. If you look under the hood on most late-model light trucks and automobiles, you will find a belt path diagram that guides you in the installation of the fan belt on your engine. It was advertised as either "Push" or "Pull". There are two bolts holding it on and one tab it sets in. 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. 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). For some, however, electric cooling fans are not only keeping the engine cooler in traffic, but they keep the engine cool at stop lights, too. The fans blew the heat several feet to the sides of the bike, and I had no leaks. However, wiring it the same way on the new capacitor reversed the rotation of the fan, thereby causing the unit to Suck In Air. Insert a small jeweler's screwdriver in the tab to release the wires and reinsert them reversed. I reinstalled the radiators, filled the bike with coolant, and let it idle until the fans kicked on. You will also be able to identify the Exhaust side as you will see power wires entering the fan motor. By reversing the Fan Wires on the new capacitor, the fan spun clockwise and the air was blowing out of the unit. To reverse the rotation, you would switch the wire leads. People on the the GL1800riders forum like to argue the merits of reversing the fans. There was also an ECM update on the older GL1800s to richen the fuel mixture. I installed a manual switch to control the fans. I found a leak in the condenser coil, in the "U" shape joint. I used two 1/4" washers on each mounting tab to regain the needed clearance. There's really nothing wrong with the engine running hotter than normal. However, you can still "reverse" the fan by simply installing it backwards. Press the "Reverse" button on the remote control of the ceiling fan to change the direction of the airflow. This presumably is for rider comfort.

Prolonged use at this speed (slow traffic, parades, creeping along) can cause the bike to run hotter or overheat (coolant puking). Is there a way to reverse the direction WITHOUT the remote? The stock setup has ~1/8" to 1/16" clearance between the fan blade assembly and housing bottom. If your 300 is running hot, and the fan is not running we’ve laid out the most common causes of this issue below. 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). You could do some testing with top-flow CPU coolers. 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 wanted to see how the bike is assembled and where everything goes. Easy onl If your fan does not have a remote control, proceed to step 2. It's getting to the fans that takes time. I installed a manual switch to control the fans. It couldn't hurt anything. These fans suck the air through the radiators and out the front of the bike.
