No, the "high output" water pumps are any different.
In reality, a properly running OEM cooling system will not allow your engine to overheat. Period.
One thing to ensure is that the new pump's impeller fins are facing the same direction as your old pump when you replace the pump. I go by the "if it aint broke don't fix it" mentality. I just replaced my pump, thermostat, hoses, belt, coolant yesterday b/c my pump was weeping.
it gets 120degrees here and I've had zero issues with overheating.
