Did they also check the cooking fan and water pump? sounds like they've done everything else.

Who did the work? A certified mechanic or some one else? Reason saying is wondering if the cooling system was purged from air.

U know what, actually the guy who's been working on it, for whatever reason he had decided to try putting his hand where the fan was while the car was running and sure enough he literally stopped it from spinning without any injury. Do u guys really think that this could be the issue?

Make sure the fan/fans are working, and bleed the cooling system by leaving the radiator cap off during warm up to operating temp. Coolant may spill out but that would be the air coming out. The level will drop so then add more coolant until it is full, all the while the car is running. Put the cap on before turning the car off.

That plastic fan blade is run on a very low power, and it's not like sticking your hand in an old V8 belt driven fan. He was 'testing' is in a very low-tech way but that works. Those fans don't even come on at about 40mph or so, there is plenty of air flow at speeds of 40 to make fan(s) useless and redundant. personally I would have used a stick ...not my hand but same thing
