I have a 1994 Chevy 3/4 ton 350 van with a coolant leak. The leak is coming from a valve on the passenger side immediately behind the radiator and below the upper hose connection. The valve is touching the AC tube that is located there. I think the valve may be a heater hot water valve.
Should I simply change the valve and go on or try to repair the leak?
