My car is overheating and coolant leak

I have changed my gasket and fix my fan as well but my car temperature keeps on going high it wasn’t like that at first but after doing over changing some few thing in the engine like the rings on the pistel and the valve seals changing that gasket. After changing all these things the temperature keeps on goin high but is it doesn’t do over heating and the fan is also working perfectly too so I want to know what is the problem

My MATIZ 3 have been doing overheating any time I drive it for 50km , I have changed the casket head several times and the tank have been washed and is still the same. Please help me
