Hello,
If you car is still overheating with new water pump and new hoses, there is still a few other things that can cause your over heating problem. Now, by you replacing water pump is good that you took care of one of the main things, however here is some other things to look at.
Number One, is your thermostat. Sometimes the thermostat gets worn out, and will not open and close properly, it is designed to open under a certain temp, but it could be stuck or warn out.
Number two, is check out your radiator, can put under pressure test, but best thing to do is a radiator flush, and see if flows proper. Sometimes the radiator core/coils get clogged.
Number Three. Check to see if your fans are coming on and proper speeds, normally as car gets to a certain temperature, they will kick into high speed.
Last thing, is make sure you have no head gasket leaks, as this could cause over heating, best way to check that, if its not obvious is, pressure test.
My opinion what I would first check, is the water thermostat and then radiator flush, if fan is working.
Thanks Mike.
