Instead of answering your question directly, If you click Search up the top of this webpage, then type OVERHEATING into the space provided, you will find numerous threads dealing with the problem. First thing I would check is the actual condition of the radiator, especially the fins in the lower front half of it. It probably needs a recore.

Two obvious points to verify.
1 Is the thermostat opening or stuck shut.
2 Is the water pump doing its job.

'93 may have been a bad year for radiators. It took me a long time to find where the water loss was in my '93 Applause:

Pressure cap? Mine was furrowed on the bottom: look at the rubber valve seat. There were adhering wee deposits of rubber on the brass seat of the radiator filling spout. Fitted a new pressure cap, after cleaning away the hard rubber deposits below. HOO BLOOMING RAY.

Nice to know its sorted.Pleased you read my posting and sorted the radiator problem. I made a new rubber seal from an inner tube - much cheaper than buying a new radiator cap.

I had the same problem with my 87 F75 Rugger when I got it

was boiling when it went up hills etc, problem was the previous owner had not used antifreeze and the internals of the radiator had turned to a sticky sludge,recored radiator, new thermostat, new hoses fixed the problem....took 15 flushes to get the water clean.
