direction from that shown here will result in an increase in the fan’s power consumption, fan noise and also the air volume it moves. What would be wrong with swapping the direction of the fan to blow through the radiator towards the front instead of blowing that heat towards me? Step 2: Now switch the fan to go the other direction. Fig. The computer turns the cooling fan on and off when it receives a temperature indication from the coolant temperature sensor. I've been having overheating issues. While not all vent fans can reverse their blade direction, certain fans that use alternating current (AC) motors can, such as a 110-volt AC motor and certain shaded pole motors. Solution: This can be as simple as a blown fuse, it could be a wiring issue, or the blower fan could need replacement. One would have to monitor for a time to make sure that the temperature still stayed within the safe zone of course. ... wish i knew that before. Thanks Mar 7, 2020 #2. Lol.

So Ive purchased a H115iv2 cooler, and will be placing this at the very front of my case, but Im confused about fan direction and air direction. Try to keep the air flow in your case going in one general direction, with more fans blowing in that blowing out. The Intake-exhaust direction should go front-to-back and bottom-to-top. Make sure your fans are blowing in the correct direction.. Is it as simple as flipping the fan around or do I need to buy a hole new fan with an opposite pitch direction? Fig. The ECU signals the radiator fan to work at the precise time. I have a SVC golden gate and placed a 80 mm enermax via metal wires. If the fan is not OEM, the air volume may be off and the electrical characteristics could be different. Fig. In others as you said, as soon as comp switch is pressed fan/fans might switch ON immediately. a well meaning but obviously not so mini knowledgeable mechanic told me to put it on the wrong way around when i was putting the engine back together before dropping the whole lot back into the car.

The radiator needs to be put in a way it is not impeded by any device in the system to ensure you get the most performance out of the cooling system. Joined Jan 13, 2008 Messages 74. When the fan is mounted on the engine side of the radiator, it is a puller fan. The radiator in a closed loop system should be mounted so that the hoses of the radiator are not only either at the bottom of the radiator in a vertical mount or simply horizontally mounted, but also mounted so that the radiator i/o hoses are above the pump. The wisest course is to remove the fan and install a GM supplied part. If a vent fan is rotating the wrong way, it may be fixable. It would be easy to find the blue barrel insulated butt splice and replace them connected in the proper polarity. I was dealing with a Subaru that had an overheating problem when sitting in traffic. in some cases you will have to remove the upper radiator hose to allow the fan to come out the top. While unscrewing and de-constructing the old cooler apart I was looking at the radiator and realized there was alot of dust there, for almost no reason. It is still blowing air through the radiator from the engine bay, but at a reduced flow because the fan blade angles are incorrect. The fan assembly is attached using either small bolts or clips.

It pulls air through the radiator, blowing back towards the engine. Started by kiwi1275GT , Mar 10 2009 05:11 AM. Abstract: A focus on the present numerical study is on the fan air flow-used in the oil natural air-forced cooling system of a 25-MVA power transformer. just simply remove the top bolts and the hose and the fan should slide right out. Your cooling fan operates through a series of circuits. 99 eclipse GS NT auto trans. I replaced the ccrm and the fan connector. If you can, switch the two wires around at the motor (where it says "HERE" on the diagram). … When the temperature exceeds a specific value -- usually 215 degrees Fahrenheit -- the computer will turn the fan … direction of fan for radiator on car? ... More fans are blowing air out of the case than drawing air in, causing a slight vacuum effect. Visually check the fan if you don’t hear its noise. The fan, whether electric or engine belt powered, sucks in cool air through the radiator grill to cool the liquid coolant. The two wires to the fan would have to be connected backwards (not sure this is possible). That is your Reverse direction. Air exhausting from a fan is swirling, like a miniature tornado. Fans mounted on the outside of the radiator are pusher fans. Favorite Answer. I have been having problems with my A/C all summer (Sometimes blowing out warm air, Sometimes running continuously without being able to satisfy cooling conditions and having insanely high electric bills) and I'm wondering if the fan running the wrong direction for the last two months could have … I am too embarassed to post pics since it looks ugly but I was able to mount the 80 mm fan.
