Keep the electric fan, use a thermostat and see if you can put an OEM type fan and clutch set up on the water pump, as close to radiator as possible, if possible shrouding. The electric fan can assist in traffic, long idle, and when you shut car off. while factory type set up does the main cooling. Try what the others suggested first, it's what you got. Had good luck with "Flow Cooler" water pumps, high pressure cap, "Red Line" water wetter.
