I notice a Radiator fluid leakout frm d body of my radiator what do i do 2 stop leak,pls Helep me!

simple, get a replacement

If you are buoyant enuf buy tokunbo but if not. Take it to wedgers (agbede in yoruba). They will stop the leakage.

I had my previous car radiator fixed by them, every since no single drop of water escaped from my car.

All the best

Sounds like there is a hole in the tiny pipe work.
I had similar problem in the past.

If your radiator still looks O.K, take it to a panel beater who will use water to locate the point of leakage and weld it it close.

Before then, you need to regularly check your water level...
