Meziere water pump here . car never ran hotter than 180 even when beating on it. my fans were tuned to come on earlier and they hardly ever did.

CSR makes a comparable one for like $160 and summit also has one for about $140.

it is a damn good investment because not only does it keep your car running cool all the time you can also bleed the coolant system in a few minutes with the car off. also the freeze plug you install prevents the weep hole from soaking your opti IF it ever craps out.

PS you will have to trim the fan shroud a little bit to fit the thing in there.
