I have a small coolant leak where the coolant line from the hot water heater connects to the engine. At the engine connection there is a shut off ball valve. The leak is between the ball valve and the engine. I have not worked on this before and am wondering what the process is for fixing the fitting leak. Do i need to drain the coolant? Or can i shut off the ball valve, disconnect it, and reseal the fitting without draining the coolant? Thanks for your help!
