But at 150,000+ miles...
if youre pump has indeed failed-- things to do...
replace pump,
replace upper and lower hose
replace coolant- (which youve already been doing)
replace thermostat
by the way-- could be a failing thermostat....
change your engine oil. (you may have noticed your oil life dropped quickly with the overheat)
