And most of the time, if the fan is running constantly, it is because the sensor has slipped out of the rubber grommet that holds it in the bracket and it is laying against the engine.

I should test the sensor - heat gun to see if it switches the fan on - is it tough to get to?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Installed wing fan and connected wire plug- is their a switch or automatically on??

POST 2Original post

Automatically turns on when the engine bay reaches a certain temperature. Can't remember what temperature but go for a drive on a hot day when you come back it will be on if it works. If you're not sure connect a 12v battery to it. It's polarity neutral (can't mess up positive and negative) if you do the fan will just spin the other way. There was a TSB about that

POST 3Original post

Correct. You can test the fan function by just hooking up a jumper to it. The engine bay temperature sensor that turns on the fan resides on the right side of the engine nestled between the intake runners. Most report that the engine bay fan very rarely runs. I know mine has on very hot days in traffic, but other than that most of the time it does not. And most of the time, if the fan is running constantly, it is because the sensor has slipped out of the rubber grommet that holds it in the bracket and it is laying against the engine. Soap it up and push it back onto the bracket.

Here's a description of the engine bay fan operation from the "Porsche 996 Essential Companion".

No, you can see it sitting above the intake runner on the passenger side looking at the top of the motor. It will have a modular lead coming from it.
