Tech / General EngineIs your car making a strange sound or won't start? Thinking of adding power with a new combination? Need other technical information or engine specific advice? Don't see another board for your problem? Post it here!
The fan runs constantly when the engine is running. I assumed the previous owner wired it that way intentionally, but would the melted/disconnected connector cause the fan to run constantly?
The cooling fans are something I've been meaning to dig into, but frankly the car runs nice and cool as it is, and I've had enough other things to do with the car that have taken precedence.
The primary fan should come on around 220*. The secondary comes on when the A/C is on, or when commanded by the ECM. If it both come on with the key in run before hitting 220* and the A/C is off, the relays have probably been hotwired. It's a sloppy trick, but popular and easy. The fans don't need to run most of the time. The airdam pushes all the air necessary through the radiator as long as the car is moving. Having the fans run all the time is just wasted.
