Has your mechanic performed a pressure test on your cylinders?
Has your thermostat been removed and tested?
Using panadol for an STD infection, would simply not cure the infection.

Usually, overheating of the engine doesn't just happen, something triggers it. There are several things that can cause a vehicle engine to overheat. A clogged radiator, stuck open/closed thermostat, removed thermostat, leakage leading to air in the system which could be caused by a faulty radiator cover etc. Also, when the fan is not spinning properly or not spinning at all, the result is overheating.

A pressure test done by a competent technician as suggested by @Lexusgs430 should reveal the cause of your overheating. But before then, while the vehicle is idling, get a waterproof & place it in front of the radiator where the condenser is, if it sucks it, the problem is probably not your fan. But if it does not, your fan may require replacement. Thereafter, ensure that your radiator is not dirty.
