My 93 500SEL is overheating

I have replaced the radiator, thermostat, hoses, radiator cap, water pump, fan relays and my 93 500 SEL still overheats. For about 15 miles the temp holds at about 85 degrees C. Then it starts to climb and will vary between 100 and 110C, sometimes dropping back to 85, sometimes not. Driving or parked does not matter. Air temp does not matter. At some point the temp will raise to 120 and I hear boiling - but do not lose fluid. No foaming in oil. No water in oil. No oil in radiator. HELP!!
