Just to keep the list up to date: I spoke with the vendor that sent me the fan, and they assured me that this fan motor was pulled from a Miata, and it must’ve just been a factory screw-up. When I pull the radiator out in the next couple weeks when my dad has the money to buy its replacement. I plan to rewire the existing fan to make it turn the right direction, and while I’m at it, I’m going to try to determine if the fan was just mis-wired when it was made, or whether it was really designed to turn the opposite direction. If it was designed that way, its likely that the fan also came with a matching set of blades with the reciprocal pitch so that the airflow was the right direction even though it was the opposite rotation. What this all boils down to is this: if it’s designed that way, always make sure you either get the blades that go with the new fan motor, or make sure the motor you’re getting is designed to turn the same direction as the motor you’re replacing. I’ll report back here when I know more. On 4/27/10 5:28 PM, "Chad Douglas" <[email protected]> wrote: The plot thickens. The fault is in the fan. The harness provides 12v properly and the wires aren't crossed on the connector. The yellow wire on the harness connects to the blue wire on the fan. I connected a spare main cooling fan and it runs in the right direction and flows the right direction. Here's the strange part. A while back, my dad's main cooling fan failed And we replaced the motor. We got the fan from a respected Miata salvage parts vendor, too. I guess they got a fan from some other car that had blades that turned the opposite direction, since all we did was to transplant the fan blades from the failed motor to the new one. I had forgotten about this tidbit when I posted about this originally. I plan to contact the vendor privately to let them know that they may want to be more careful. For now, I will just install my spare fan in his car..... After we get the new radiator, that is. --------------------------- Chad Douglas Sent from my iPhone On Apr 26, 2010, at 2:30 PM, "[email protected]" <[email protected]> wrote: Do both fans run backwards? Was the car ever in an accident? Body shop are notorious for doing this type of miss wire. Trace the harness and see if there are any butt connectors. Does the car have a/c? It is amazing that the car never over heated if it does. Raj In a message dated 4/26/2010 12:12:45 P.M. Eastern Daylight Time, [email protected] writes: Wrong flow verified. Car has never overheated. I plan to get the car back soon to track this down. I just wanted to ask the list I'd they'd seen this before or I'd Mazda dud something "brilliant" in 97. --------------------------- Chad Douglas Sent from my iPhone _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower -----Inline Attachment Follows----- _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
