This is my first infinity ever, 03 G35 just a little over 160k miles. I've been through so many cars that I kept trying to keep alive with my own hands until the repairs just went past the car value and I had to get rid of them.. but this baby has never let me down and I bought it at a very reasonable price too! I was wondering though, I get the feeling the car runs too hot? And I only say that because I hear nothing but radiator fan when its +80 degrees outside. Especially with AC on. I get it that adds more load but it seems excessive.

 

Welcome, it's a pretty car!

 

Congrats on the new ride! The paint looks absolutely mint!!!
Some 2003 cars have a mechanical puller cooling fan + one electric pusher fan. 2004 they switched to dual electric pullers. Some have noticed that the mechanical fans are noisy. My electric fans = on 204*/off 190*
I'd check to make sure your thermostat isn't sticking closed, as well as all the radiator and hoses are all in good shape. Also, these cars are susceptible to air pockets in the cooling system
One thing I learned (by dumb luck) is that the 6mt cars came with a 170* thermostat, whilst 5at cars have a 180* from factory. I have the 170* in my car (04 Sedan 5at), and my fans rarely come on - unless I'm sitting in stop-go traffic or its 95*+ out. If you change it out, go OEM or Nismo. Aftermarkets seem to fail, even when new!

 

If the AC is on both fans should turn on an run at all times.
