How to Identify a Leak at the Radiator Tank

This Honda Civic has a bad radiator, it is leaking where the radiator tanks meet the metal of the radiator body. This video shows how to locate a similar leak on your car. This is a typical failure of most cars with radiators with this type of metal and plastic radiator. This radiator problem is not unique to Honda.

This leak at the radiator tank seal is probably the most common radiator failure, I’ve had this type of radiator leak on several of my own vehicles.
