Okay so I have a 2000 STS. I replaced the thermostat ,water pump, coolant temp sensor, and reservoir. It used to over heat right away but after flushing the coolant it doesn't overheat while driving. As long as under 4k it's cool, but when idling and accelerating faster than 4k it overheats. I'm at a loss of what's causing it. I drove it 25 miles nice and easy no problems. Any help appreciated!
