I guess the first thing is to true confirm it is pushing. Fan running and holding a piece of paper on the front of the radiator would tell you that.
Do both fans run the wrong way?? Next is to jumper the fan directly to a 12V source and reverse the wires to see if the fan changes direction. Then measure the + and - feeding the fan from the harness and see which way it is wired. This car never overheated in the past?

I've never seen a pusher in any car, come to think of it. I can only assume that it's been like this for some time, since I've been familiar with that car for the last 160,000 miles (my buddy bought it atr 27k and then later sold it to my dad), but never had cause to check fan flow direction. I guess I could trace the wires a bit, but unless someone hacked the harness in the past before the car had 27k on it, I can only assume that the fan was mis-made. I'll look into it further and report back. On 4/26/10 6:11 AM, "Larry Alster" <[email protected]> wrote: I think you need to figure that out. I've never heard of the Miata pushing the air out the front of the car with the fan, makes no sense.

I just put the motor back in my Dad's Miata and while run testing it, I discovered that the main cooling fan is running backwards - it's pushing airforward through the radiator instead of pulling. To my knowledge, nothing has been done to the wiring on that car. Have you guys seen this before, and if so, should I make it flow "right" or just leave it. Car is a 97STO. I swear, these 97s are the biggest pieces of crap to ever bear the badge "Miata." I've seen more bizarre issues with 97s than any other year of Miata.
