Can someone tell me if this is the fan clutch? I have been searching for an answer but I'm just not sure if I have the same thing going on... So it's usually only in first and second gear sometimes in third that I hear a loud fan noise (bus,jet,semi,etc. I have seen described as) the noise follows the rpms and seems to stop in third to fourth gear and the thing is it isn't everytime I hear it. About 90% of the time I do but sometimes there isn't the loud fan noise when I take off in first and second?? Also I keep an eye on the temp gauge and it seems to stay right in the middle no over heating or over cooling. I spun the fan when engine is off and hot and it spins but stops as soon as you remove your hand no free spinning and it's exactly the same this morning with the engine off and cold. Is it supposed to keep spinning by it's self atleast a little bit? It's not so tight that it feels locked up or anything so im not sure if it needs to be replaced. Also the guy gave me a new radiator with an electric fan attached to it that he never installed. Does this replace the fan/fan clutch once the new radiator is installed? Or would both fans be there. For all I know this might just be a normal loud fan on the car but I'm just not sure, this is my first Z and I'm not to experienced with them.*

 

It's doing exactly what it's supposed to do, it's loud and fallows the RPM's because it's attached to the water pump. Also the temp gauge in these cars are pretty worthless, you can be pushing 210* coolant and it will still sit at the half mark. Take a pic of the radiator/fan setup, about 99% of all aftermarket fans that fit these cars are worthless, but then again the stock radiator is VERY small for the application.

 

Ok here is a pic of the radiator/fan I don't see any brand name or anything on it so it's probly just a crap one.


Also there is a high performance thermostat that he gave me. Is there any reason I should put that in? The engine is pretty stock.

 

I wouldn't worry about either unless you start seriously modding/tracking the car or live in a very hot climate.

 

Ok. Thanks for the advice.
