About a week ago after getting a new cat installed, my car overheated on the way home from the muffler shop. Since then I have replace the water pump and the intake gasket. I am still overheating, the system has been bled and pressure tested. The coolant leak was coming from the intake gasket, had it replaced, and it's still overheating. Then I thought it could be the water pump, so I just replaced that and It's still overheating. Car runs perfectly, no stuttering or anything temp just gets too hot and i have to shut it down and let it cool off.
