Need help coolant leak.

So I have now replaced every hose and the radiator and I still have a leak. I went back and redid it all and made sure everything was nice and tight but still has a drip.

It's coming from the passenger side of the car maybe it's the tank?

It could be a hose. It could be your expansion tank. It could be your radiator. It could be many things you will have to take it apart and look to find out for sure. Or have somebody hook up a pressure tester and see if you can find the leak
