overheating

Has the coolant been changed or drained and replaced recently? Is the coolant green or pink?

I bought the car few weeks ago i dont know. The coolant is green

So you likely have "coolant pudding" instead of coolant. The car uses pink coolant from the factory. Dumping in green prestone causes a chemical reaction that thickens the coolant making it unable to efficiently cool the car.

Anyone familiar with how to get a positive diagnosis and clean up this mess?

That's not completely correct. There has also been green factory coolant. Porsche has also used yellow. The current color is pink

I just changed my WP and coolant and what came out was green and it was factory coolant

And my 2003 was pink. No idea if it was factory though as I was not the original owner. So, do you know how to determine if it is coolant intermix?
