I have seen cars equipped both ways. On mine, I just swapped the wires until it was blowing from grill, to radiator, to engine.
Well the fan that I have doesn't have any wireing, just 4 blades on one side, the connection. I may need to check the color cordination at a junk yard to get a visual on order. Thanks ron
Well the fan didn't fit, that's ok though. I like the way it's turning out anyway.Working on the cooler lines next weekend.
Of course you did. Because we all know you have junkyards confused with auto parts stores. Yeah....electric motors tend to do that. Wonder why? It'll work.
It didn't. This thread is very old. When I wired it up to push, it sounded like an airplane, it was louder than the engine. It was nearly silent when wired to pull. It lasted about 3 days like that, the burned up. I bought another fan that was thinner and kept it wired to pull. It has worked fine since. The shape of the blades were such that it was really designed to pull, and when it went backwards, it lost it's efficiency and made awful noise. If it had standard blades, it would have worked well either way. It burned up, but I don't think it was due to the reversing of the direction. I think it was just worn out.
reversing the direction will change the loading on the motor, less drag is just as bad as more drag on electric motors.
Not true at all. The majority of electric motors are single speed and designed to run at a specific rpm. Loading down an electric motor will cause the motor to draw more current to maintain that rpm. More current also produces more heat. Heat is what destroys electric motors. An electric motor that has no load will run almost forever.
