@herickpereira a cracked block/heads or a bad cylinder head gasket are on top off my list. You need to tell us if you noticed water in the engine oil, oil in the coolant etc. Remove your spark plugs and lets see what those faces look like. It'll tell you a lot about how your engine is burning its fuel. Do a compression test followed by a leak down test and let us know what those numbers shows you.

Of course. let's not forget the obvious. Make sure that your cooling fan is working, that your radiator is not loosing coolant and that you have enough coolant in your engine. Check your water pump as well. Now, there are two simple ways that I know off and both require you to run your engine. MAKE SURE YOU KEEP YOUR HANDS AWAY FROM ANYTHING THAT IS ROTATING! DO NOT WEAR LOOSE FITTING CLOTHING ETC. THAT CAN BE GRABBED BY THE BELTS ETC.

With your car having warmed up (NOT HOT), squeeze the upper radiator hose and rev the engine. You will feel the pressure in the hose pushing back against your hand.

On a COLD (NOT HOT and NOT WARM) engine, remove the radiator cap and start the car. Rev the engine and the coolant should rise and overflow. If so, your pump is working.

Let us know what you find out.
