Tolerance of water pump play?

Not sure on the miles, odo doesnt work lol. Its about 5 years old. Correct, quiet while running, just can hear it when i push in on the fan at the top. I know its the water pump, i have a fixed fan, you know i probably need to check the fan bolts and make sure they arent loose and causing me to confuse play in the pulley with play in the water pump. but im 99% sure the play is in the water pump
That was my point; it's best to pull all that junk off.
And yes it's better to use a matching hi-flo thermostat. My 195 has been in there just as long as the pump.
Like YR says, and mine seems to open faster and further, and I can even see it on the factory slow-performance temp gauge as the needle no longer overshoots the "normal" mark..
