Ok so i hit a steep pothole now my car is overheating! i opened the hood and found some coolant over the engine bay. now i just replaced the radiator and its still overheating im not sure what the problem can be please help!!

 

Is it still leaking coolant? Did you bleed the cooling system?

 

Bad thermostat?

 

Warm up the car until the fan kicks in.
Ensure:
1) Cooling system is bled and there are no leaks or air.
2) Fan turns on at necessary temperature

If the car is starting to get warm, pinch the upper hose, if you feel that it's warm with coolant flowing then it's circulating, then compare that with the lower hose. If the lower hose feels cold and doesn't have any circulation then you're likely to have a bad thermostat. Purchase an OE replacement and a thermostat gasket at a parts store or RockAuto then it should repair it.
