There's really nothing wrong with the engine running hotter than normal. That won't be easy to do since these are all nicely integrated onto a small board. If the radiator fan is not working, it’s a serious problem. If possible, mount your radiator and fans as exhaust fans. I installed a manual switch to control the fans. In It's getting to the fans that takes time. Going uphill, pulling a trailer, hauling a passenger, etc., makes the situation worse. The Derale electric fan, # D18914, is a pusher or puller fan. Insert a small jeweler's screwdriver in the tab to release the wires and reinsert them reversed. It was advertised as either "Push" or "Pull". Overheating...coolant puking...is bad. I have a real temperature guage so I can see this happening. If your 300 is running hot, and the fan is not running we’ve laid out the most common causes of this issue below. Find the fan for your application from our search engine. Three washers were too tall. That said, I think there is an unsettling feeling about seeing the temperature guage going up and up towards the red. The stock bolts are too short to be used with the new shims. I want it to "Push" rather than pull as I can only mount the fan in front of the radiator. It's getting to the fans that takes time. 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) ? ", the customer's own vehicle holds the clearest answer. My Hampton Bay Sautern fan came without a remote. The principle is same, air is pushed through heatsink and rest is flown over VRMs as passive cooling. I think a secondary thermostat switch has been pondered by a person or two. You likely won't find a product marketed as an electric pusher fan kit, it's usually just a normal electric fan designed to be reversable. Update: After having this mod for four years I can say it's a very worthwhile mod (for me). I found a leak in the condenser coil, in the "U" shape joint. 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). Insert a small jeweler's screwdriver in the tab to release the wires and reinsert them reversed. I can also keep the fans on longer than the ECU normally would and allow the bike to cool even more. I know I don't like it...whether it's actually okay or not. You still have the poor airflow in the 15-25mph range that can cause rising temperatures. This raised section will have a … It was advertised as either "Push" or "Pull". Easy onl However, you can still "reverse" the fan by simply installing it backwards. I reinstalled the radiators, filled the bike with coolant, and let it idle until the fans kicked on. But for the sake of completeness: water cooled components have a minimal effect on the internal airflow of a case. I have reversed the positve and negative wires and the fan continues in the same direction. Is there a way to reverse the direction WITHOUT the remote? There was also an ECM update on the older GL1800s to richen the fuel mixture. A fan mounted on the front of the vehicle on the bumper side should push air through the radiator. All engines will do that when put under a large load. It couldn't hurt anything. 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. The last thing to modify is the plug. Repeat for the other radiator/fan assembly. The motor is not physically reversed. \$\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. Supplying negative power won't work, just fry the electronics. Fan runs backwards. It couldn't hurt anything.
