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.

You may have air in the cooling system. Try bleeding it. There's a bleeder valve on the thermostat housing. Open it, with the engine cold, remove the radiator cap and add coolant until you have a steady stream of coolant coming from the bleeder valve. It's helpful to park on an incline with the front of the car pointed up like halfway in the driveway. If you're between about 90,000 and 120,000 miles you're due to have the intake manifold gaskets replaced. They're notorious for failure. If you have the non-supercharged 3800 V6 replace the upper intake as part of the repair. Don't reuse it. They crack. Be sure to replace the lower intake gaskets as well. The lower intake manifold, if not warped, can be reused. HTH. -Jim
