1997 Geo Metro Water Pump Bad? But not leaking

Hi my name is Connie Bustamante, and I have a problem.
I drive a 1997 Geo Metro 4Cyl. Automatic. I have owned this vehicle for about 8 yrs. My problem is that my temperature gauge gets really high and actually overheated last week. I have had this problem for about 2 months now. I do not have a leak but could not figure out why the temp. Gauge would get high. I checked to see if the fan worked. It works, thinking it might be the radiator I checked for a leak. No leak it holds the coolant fluid. Thinking it was the thermostat I changed it and still no luck. So then I figured it must be the temperature sensor. And still no luck in fixing the problem. So then I changed the hose on the bottom hose that connects to the radiator. Still gets hot, I took it to a shop thinking maybe it needs a coolant flush. However they decided to do a diagnostic check instead and $100 later they told me what I already knew. The fan, radiator, thermostat, temp. Sensor, radiator cap and hose is fine. They said everything was circulating okay. But it may be the water pump. I had the water pump, radiator and timing belt replaced 4 yrs. Ago. My water pump has no leak and seems to be in good condition. Could it be the water pump if it is not leaking and still looks good? I can not for the life of me figure out what is wrong with my car. Do you have any suggestions as to what could be wrong.
Do you
have the same problem?

Try a full cooling system flush.

Next with the water pump, lots of them fail without even leaking, the impellers inside can corrode right off.

To let you know a lean fuel mixture can cause overheating so can a faulty head gasket.
