Cooling system issues

I’m guessing the face of the pump body at the impeller is quite pitted.  Sounds like a new pump should help.

I've had very good luck with 160 degree thermostats on more than one car.  Before putting in the 160, my car's occasional temperature rise was a concern.   After the 160 install, the temperature gauge rarely gets up to horizontal, and never above it.  The rest of the cooling system is totally stock.  While I'm probably losing some engine efficiency, the peace of mind seeing that needle so low is worth it to me. 

 

I'm not proposing that this would cure the cooling/circulation problem in this case- it seems like more is going on here.

Update: got a new water pump and had the radiator hot tanked, flushed and tested. Put everything back this afternoon and it seems to be working. Need to get under the car to tighten up one of the hoses and open the front to remount the electric fan but it looks like I’m in the clear.
