I have a little leak from the driver's side of the radiator. I've checked the (new) hoses and the thermofan switch (new) as well as the drain plug (new), so I'm coming to the conclusion it's the radiator itself. The drip always comes from the tab for the undertray bolt shown in the photo.
I can pump up the pressure in the coolant system to about 10psi (don't want to go higher) using a Mityvac pressure tester ... it very slowly drops, and as it does so I can hear a fizzing sound from the radiator, driver's side. But I can't locate the source of the fizz.
Leaky radiator? Should I replace it or live with it?
