I am losing coolant as fast as I pour it in. It seems to be coming from the back passenger side of the radiator. What can be the cause?

One possible cause of a radiator leak is a faulty radiator cap. The cap is what keeps the coolant in the radiator, so if it's not working properly, the coolant can leak out. Another possibility is a hole or crack in the radiator itself. This can be caused by corrosion or physical damage. If you're losing coolant as fast as you're pouring it in, it's important to have the problem diagnosed and repaired as soon as possible, or you could risk damaging your engine.
