Something wrong with the temperature sensor? If the sensor is broken, it will not start the fan when required?
Another possibility - blocks in coolant circulation path within the engine block.

best is to do a pressure test. If it holds pressure then good.
Now zero in on the Pressure Cap. Test the bugger also.
cheers

There is a thermostat device in the cooling system, which causes the coolant to bypass the radiator. This is to helps heat up the engine to optimal operating temperature fast. Once this temperature achieved, normal coolant flows through the radiator.

It seems in your car, this is faulty and not allowing the coolant to pass through radiator.

first its located normally on the top hose section meeting the engine. dont worry on checking the thermo as its a simple test to do but will be technical for you to do. just take to good garage get it pressure tested and get the Radiator cap pressure tested.

The cap is such a small item which controls a lot just like a pressure cooker.

This is something which can be checked only at a service centre. The location would vary for each engine. I used to be a service engineer with Tata during the good old days of Sierra/ Estate. This was the first thing checked whenever anybody complained of overheating. Many local mechanics actually remove this totally (not desirable).
