Engine light appears and states.Reduced engine power stop car when safe to do so

Hi This is my car. Got it home and the temp was way overheating. Put a new Coolant Temperature Sensor and new antifreeze. Nope not it. Maybe a Waterpump? what else dave could it b

A coolant temperature sensor would rarely -- if ever - affect the vehicle in a way you have described. An overheating condition is most often related to: 1) Thermostat not opening fully when needed 2) Cooling system flow issue - such as clogged radiator or restriction somewhere 3) Engine cooling fans not working properly 4) Air pocket in the cooling system not purged during a previous repair 5) Internal engine coolant leaks causing exhaust gases to get into the cooling system I wouldn't guess at anything here. Water pump would be an unlikely cause -- it's possible but more rare that the impeller of the water pump would detach and prevent coolant circulation. Good luck.
