    Hi A total car idiot here. Have a 2014 civic (automatic ) with 50k miles . Noticed after a 2 hour drive the other day, on very hot day, with air con on, a hissing sound after the car was turned off. If I look under the bonnet, it seems to come from the left side of the engine. Maybe mid depth...
