The fan, whether electric or engine belt powered, sucks in cool air through the radiator grill to cool the liquid coolant. Not sure how to fix it. If the fan is not OEM, the air volume may be off and the electrical characteristics could be different. Fig. 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 repair personnel were probably NOT electricians but body technicians. I had an HVAC tech out that said that my fan had been running in the wrong direction. Step 2: Now switch the fan to go the other direction. That fan is on the wrong way round. The two wires to the fan would have to be connected backwards (not sure this is possible). Favorite Answer. checked the wring of the extractor fan against one which does work properly, and they are the same..

You want both fans on the radiator going the same direction. 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 … Is it as simple as flipping the fan around or do I need to buy a hole new fan with an opposite pitch direction? I have a SVC golden gate and placed a 80 mm enermax via metal wires. Eg., if you have a fan on the back of your case exhausting air, and you are mounting the radiator in the front, you want them blowing in into the case (pull configuration). 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. Which direction does radiator fan and cooling fan supposed to blow. The Intake-exhaust direction should go front-to-back and bottom-to-top. Fans mounted on the outside of the radiator are pusher fans. 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. If you can, switch the two wires around at the motor (where it says "HERE" on the diagram). A radiator fan is not very expensive and can cost around $200 – $400. High and low speed work just spin the wrong way … 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? 1: Example of a bi-directional fan.

Air exhausting from a fan is swirling, like a miniature tornado. The "fan" is usually a cylinder with curved ridges designed to push air laterally towards the ducting and not actual fan blades like in a ceiling fan that would push the air vertically.

Your cooling fan operates through a series of circuits. The computer turns the cooling fan on and off when it receives a temperature indication from the coolant temperature sensor. 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. It's a 3 wire connect. I am too embarassed to post pics since it looks ugly but I was able to mount the 80 mm fan. That is your Reverse direction.
