Mazda 323 B6 engine rehearses, and has no strength

Hello friends, I have a 323 mazda, and the overheat engine at the end of inflating the hoses, apparently the previous owner made him brush the cylinder head, put 1.9 mm packaging, I changed a new water pump, I did the cleaning of the radiator and the engine refrigeration system, I took out the thermostat but the problem is still strength, please if they could help me, thanks

Are you using the correct dose of coolant? It has to be ethylene glycol, at least. It can be a compression loss failure to the cooling system, you can verify it by compression test to the engine or the sealing of the cooling system, (better if they are both). Those hoses that swell when the engine will heat up too much when fluctuating the liquid. Change them too. If nothing occurs, you must manually cover your engine and verify if it is correct, according to the displacement.
