I have a 1999 cadillac. It has a year old radiator and water pump. There are no leaks any were. The thermastat is not the problem. After it hits normal temp it starts to flood the overflow and overheats. I checked the oil and there is no signs of water and there is no white smoke coming from the exhost. I also changed the cap to the over flow tank. I am now thinking it might be a clogged radiator. I have also changed the ETC SENSER. The cooling fans work fine to.I NEED HELP

Before you spend much time, or money, have it checked for the presence of combustion gases in the cooling system. It is common for internal leaks, and you won't necessarily have intermix, or excssive exhaust to indicate.
