Hello everyone:

I noticed a radiator leak dripping from the rubber grommet on the passenger bottom side of the radiator. I checked to see if the leak was coming from the drain plug but it wasn't. The leak appears to be dripping out the bottom of that rubber grommet. Any idea what caused this and how to fix it?

I don't want to put any stop leak in my radiator. I prefer to stop the leak the right way :)

You should pressure test the cooling system and/or remove the radiator and take it to a shop for a pressure test.

If the rad is leaking it's likely you'd be best off replacing it (unless a shop says it can be reliably repaired).
