Is there a radiator fan on the 2003 g35 sedan?
So it seems like my engine overheats where sitting idol with the AC blasting. If there is some air blowing the the engine temps are fine, but sitting in traffic with the AC on is stressing the car out.
This car was apparently "Clean" according to carfax (yea, thanks car fax. good job), but my mechanic and few other people agree that it was hit form in the front. I told him about the overheating problem and we both concluded that maybe the radiator fan motor might need to be replaced only to realize that there was not radiator fan (hope I'm saying this correctly, I'm not car savvy)
Is there fans on to of the radiator or would it be a different problem? If someone has pics of their front without a bumper that would really help. The cable for the radiator fan seem to be there but no fans.
I think this is how the fans look: http://cgi.ebay.com/ebaymotors/Infin...item19c5d84700
Thanks

I have an 03, it has a mechanical fan and a smaller fan as well. While sitting idle mine heats up after a few min's as well, seems to do it only in 90+ weather. I usually pick up my little cousin from school and I typically cannot wait long with the a/c running because the needle starts to rise. I'm thinking of changing the water pump and thermostat.

I am changing out my radiator but have to remove the cooling fan and clutch. Does anyone know if I can just unscrew the fasteners from the clutch without loosening the pulleys first. The pulley seems to be connected to the pulley bracket but I don't know if that fastener goes all the way from the clutch to the pulley bracket. Just don't want to do more work than I have to. Thanks for any help.

^Good job asking before causing yourself more work!
You absolutely need to remove the belt before the fan.
The actual pulley is "sandwiched" between the flange on the fan clutch and the flange on the bearing.
I didn't realize this when I did my radiator, and thought I'd save some time by simply unscrewing the fan and putting it back on. It wasn't obvious that the pulley was it's own piece, but when I put the fan back on and tightened all the bolts back, the pulley had made itself slightly off-center because of the belt tension. This lead to a weird vibration that very quickly destroyed the bearing.
Fortunately, the G isn't like a lot of old-school cars (I'm looking at you GM) where the fan pulley is also the water pump, even though the aluminum bracket that houses that bearing actually looks like a water pump.
Now, that being said... When I destroyed that bearing (for which you have to replace the entire bracket) it gave me enough reason to go ahead and do an electric fan mod, which allowed me to remove that bracket entirely, take 1 pulley (fan) completely out of the system, and re-route using a smaller belt, which really helped make extra room on the front of the engine for a large e-fan. So, something to think about... if you ever want to go to an electric fan, now is a really good time.
