Do you put coolant additive?
Did you check belts? Water pump?
Check water level in the morning and again in the next morning, observe.
To check for leaks, in the evening after a days run put newspaper under the radiator and w.pump area and leave it. In the morning check for stains.
Avoid cavitation or air pockets in the system, this spots will heat up the engine rapidly.
