It doesn't fully boil the coolant, but the heat signal comes on and goes away. If I use the A/C it also overheats. I have made sure its bled right. I suspect the radiator is blocked. Please help.

When it is overheating can you hear the cooling fans come on by the radiator? If so, I agree with you that the radiator needs to be replaced. Here is a generic guide on how to replace the radiator with instructions below to show you how to in your car.
