Radiator Leaking
I have Toyota corolla 98when i use the fan i get some wired noise like something getting scratch or something. When i open the hood and look it looks like some thing is leaking probably the radiator i'm not sure if radiator is leaking or something else any possiblity for anything?also if radiator is leaking then do i need to replace the radiator or any fix like stop leak or similar product will be sufficient?
