Infiniti: 1994 Infinity G20 Water Pump Torque Specs.

I have a 1994 Infinity G20 that I just bought. When I bought the car the
dealership I bought from said they just replaced the water pump. I live
in Arizona where it gets a little hot!!! When it is real hot the water
pump leaks. I am thinking it is not torqued properly. Does anyone know
what it should be torqued to? Appreciate any help,

Thanks
