Stop leak is designed to "fix" leaks by blocking the leak. Problem is, it doesn't know what is leaking so it can block the tubes in the radiator and in the engine.

What is leaking? You can get a replacement radiator for under $200 new. I would not recommend using stop leak in any car or truck you plan on keeping.

Thanks, NO stop leak.I will just top up the loss, it is only about 200cc's in 500Km. No leak when stopped and cold.

More than likely the plastic expansion tank is the issue. Mine was leaking at one of the crimps where the tank gets attached to the aluminum radiator. I could only find mine when I pressurized the radiator with 8-10 psi.
