You need to flush the radiator and inspect the cooling fan to make sure it is working. If the radiator is in bad shape you should get a new one.

When you say "still running hot" ...is the engine actually overheating or is the warning light coming on ? There is a chance that you have a faulty sending unit. The 3800 do not commonly have a overheating issue, some models did have a plastic intake manifold that cracked and leaked water....usually into the intake system, you could be loosing coolant there and causing it to overheat.

Check your catalytic converter pressure, by removing the O2 sensor before the cat. Pressure should be no greater than 1 psi.
