When a car comes to me with this problem I automatically replace the water pump, thermostat, and ECT. I've done this repair and all 3 pieces look to be in good working order so don't assume you can inspect the parts and see which one is broken. I wouldn't trust aftermarket parts either(except for the water pump, plastic impeller sucks). Never had one come back for this.
