I've got a coolant leak on my '07 350z I was hoping I could have some help diagnosing. I took a video showing the leak - this is with the car off and no pressure on the coolant system. I just opened the radiator cap and filled it up with some water.


I only know to check the radiator hoses and those looked OK. Appreciate any help you all can provide

 

Difficult to tell from the video. Check your coolant hoses leading from the throttle body. There are multiple hoses, and one that crosses over to the other throttle body, near the firewall.
