Bill, you might want to start with a few basic checks. Check the entire cooling system for flow (maybe backflush the block), also make sure there is no water leakage into the engine causing heating to increase. Install a new thermostat w/small hole drilled for a by-pass. Verify that all hoses are good (no collasping when under pressure) causing a restriction. Bleed system for air. If it still runs hot inspect water pump and verify your fan system, sometimes there is too much of a voltage drop which can slow your electric fans. In addition, verify your actual water temp. gauge..they go bad all the time, use an heat gun and a themometer in the water. Good luck.
