2011 G37 overheating issue
Hey guys I’m fairly new to the G world, I have been driving a 2011 g37 sedan auto for several months . Last night I took my first road trip in it ( 300 miles ) and it drove amazing however today driving around the city it’s over heating at stops ONLY, once I start moving it drops fast , the fans are working and coolant is at max, anyone have a idea what it can be ? Thermostat ? Any help is appreciated as I must drive back tomorrow and need to fix it today . Thanks guys/galls

Start with a coolant flush and a thermostat. I had several overheating issues I live in AZ with my car especially in the summer stop and go traffic. Most of the time it was due to air in the system. I just started overheating like two weeks ago again went ahead and did a full coolant flush and bought a mishimoto racing thermostat and also added water wetter and helped a lot. He mishimoto thermostat will open up lower temp than the oem one. I got a shop to do it because these cars are hard to bleed so make sure all the air is out the system

I had mine creep up in the higher temp range on the dash gauge, this was in stopped traffic in Vegas a couple summers ago when it was over 115 degrees outside. I did a complete coolant flush and it's been fine since. I only use the Lisle no spill funnel kit and followed the DIY link on site, pretty easy w/ that kit and the DIY info.
