Way is my car over heating I chaged the water pump and the Stat

Possibly the radiator, touch the radiator top and bottom side to side. if you find cold spots the radiator is blocked and needs flushing or rodding out.Be careful of touching the radiator when the engine is running, don't get near the fan blades. You might look at the oil filler and radiator caps, if you see what looks like a chocolate milkshake this could be an indication of a bad head gasket or block allowing water to mix with the oil or visa versa. good luck.

Change your thermostat..thete are three bolts connecting it to body of engine..from the radiator.thermostat not opening.
