    So like title says, I have a 97 lude base model. Temp gauge goes up to about 3/4 and then the radiator fans kick on. I hooked a scanner up and found that the fans are turning on at about 214 degrees F. From what else I found the fans are supposed to kick on at 199 degrees F. I know that its not way overheating, but still runs hotter than factory spec. Maybe this is normal or maybe I am missing something, idk. I'm not real familiar with preludes.

    Just for reference: only CEL is an EGR insufficient flow code, not really related, but thought I would mention it. Also I replaced the rad fan temp switch (on the t-stat housing) and no difference.

    Hope you guys can help!

    Have you tried changing out the thermostat?

    Are you sure it's the fan? Sounds to me like you may have a higher temp thermostat. You can go to your local parts store (o'reily's, autozone, etc.) and they can give you one for the stock recommended temperature.

    lol I know where to get a t-stat. I didn't think that the t-stat would be the issue, simply because I thought that if the temp sender sensor was right, the fans would kick on regardless of when the t-stat opened. But I guess since the sensor is on the hose side of the t-stat and not the block side, then it wouldn't get a reading until the t-stat opened?
