Have a 2004 Grand Prix that has started overheating. Put a new thermostat and water pump in. Now when I drive the car it starts getting hot when the car is coming to a stop or slowing down and loosing water/coolant. Hoses all seem to be fine. Last summer I had a new radiator, a/c condensor and heater core put in. What could be causing it to still run hot?

Could be air in the system try bleeding it -Cooling fans are they operational?

BLEEDING COOLING SYSTEM
Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.
