My fan is running good I just changed the thermostat I burped it and still I'm overheating what's wrong

How is the air flow through the radiator? Is there any debris or restrictions? Are you having the overheating occur more when the car sits still or when you are driving at a decent speed or accelerating? It's too hard to know what's going on without hands on assessment of the cooling system performance - including checking the cooling fan operation to verify that the proper speeds are available, and that the fans are coming on at the appropriate time. A cooling system restriction should also be checked for. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
