Well if you are going to replace it go with the 8 blade AC pump IF it does not cause a mounting issue for the altanator etc and the hoses.

Will move a little more water but the fan and radiator are the main coolers.

190is normal on a warm day.

How would it work with a 160 degree themrostat what would the temp of engine be

 

[RedFish]

the thermostat would open earlier but open is open. Operating temp wouldn't change.

Put a 180* thermostat in it.....a 160 will not let the car warm up properly and can cause higher temps cause it will open and never close and not allow the radiator to fully do it's job.
