G35 overheating on hwy at 80mph
Hi guys
Brand new here and I need so help. Recently my 05 coupe overheated due to the thermostat sticking. It was replaced, ran fine. A few days later I noticed the temp climbing while on the hwy, brought it back and the proceeded to bleed the line again. Ran fine. Now it's hit and miss, when I'm on the hwy doing 80mph at 3000rpm the temp starts rising. When the rpm's drop the temp will drop. Stop and go traffic and city driving it runs fine. Runs fine on the hwy until i hit about the 20 mile mark at around 80mph. A/C and heater work as they should. Also fans are working. The lower splash gaurd is not on but it never has been, and the car is stock. Help!

Have you followed the troubleshooting steps in the FSM?

Did you perform a pressure test?
Replace the radiator cap
Perhaps you have a clogged radiator or a defective water pump?
