According to the previous owner's service records a new water pump was installed 46k miles ago and 31k miles ago a new radiator, upper radiator hose and coolant sensor were installed.
Radiator looks clean on the outside

The water pump is "relatively" new but from the horror stories posted on the board it may be worthwhile to change it out. Will order it soon. Any suggestions on a brand? Are plastic impeller failures still an issue?

TIA

check your aux.fan if it works in high mode...might be its low all the time
