working on the g35 today and noticed a spray/spark coming from the left side of the engine bay by the main radiator hose. Looked around and could not figure out what it was or where it was coming from. Any advice would be great. Car has roughly 130k and runs great so this is new to me. Please give me any problem shooting you may know about. Could also be rubbing of the belts below but could say for sure.

Thank you everyone!

 

Looks like coolant spraying from a hole in the coolant line, Follow the spray to the source.

 

After looking at it again that is what I am figuring as well. Probably need to replace the hose. Thanks for replying.
