It could be any of a number of things. It could be a coolant leak, the timing may be off, the radiator may be partially plugged up, the fins on the radiator may be bent together to where not as much airflow is going through them to cool off the coolant.
The cooling fins could be blocked by anything that got in-between them, or is limiting the air flow to the front of the radiator. The cooling fan could not be working, or even running in the wrong direction. (Don't laugh about that one, my friend had his thermostat, radiator, and coolant replaced before he had me look at it. And I had to check everything else before I finally figured out the reason for the overheating) It got very frustrating for him that 3 different shops could not figure it out.
Also, the water pump can either be leaking, or the impeller blade on it may have deteriorated if the coolant has not remained clean. The cooling system may need to be reverse flushed. Or the thermostat may be stuck, and in need of replacement. Anything I missed as a possibility? Don't think so, but I am just a backyard mechanic that mostly works on my own cars when I need to. And sometimes helps out friends.

Provided the mechanic did his job well and the sender unit for the gauge is ok and has fitted a new radiator fan relay. Sounds like there could be a blockage in the rad, try flushing it thru with a hosepipe. Also could be an airlock. When you refill, ensure the heater is turned to maximum heat setting and run up until the engine is warm. Feel each of the hoses when warm and check the heater output to determine if the water pump has failed. You can also sometimes see water coming from the weep hole in the water pump housing to indicate potential pump problems. the water pump is not pushing the water around the system. is the radiator cool while the engine is hot? the rad fan will not start if the rad is cool. the impellor sometimes falls off the water pump spindle, hence no circulation. but of course without having a look its difficult to be sure. As suggested above you could of course have head gasket problems. Good luck. Are you able to remove the connection to the thermostatic fan switch and short it to very the fan is OK ?

LOL. Ummm.... hows the coolant level? A stuck closed thermostat, perhaps? Could be lots of things really....

overheating means it will take time to re-start, if it is so then rectify otherwise it is ok; temperature meter may be defective.
