Can it be an electrical problem that is heating the truck?

please thank you if someone can help me.

since I can't walk in the truck normally ..

thanks in advance

If electro and thermostat are already discarded then the most caused thing is that it is a cylinder head problem, especially if you already changed the water pump could be packaging or the cylinder head itself. The Catalitian has nothing to do and there is no electrical problem that affects the temperature unless it has to do with the electrventilator system but if you have it direct, it would not be right to think about a system failure, it could also happen that the fan turns very slowly to cool or that for some reason it is turning the other side.

Thank you friend for your answer the truth that I have thought a lot that it can be the butt wants to have to send it to rectify, but first I would like to be sure I do not know if you or a friend could tell me the symptoms that the cylinder head is so bad so that the truck hot, I would like to please her help since she would be the last thing I have left to try because as my subject says I have already done everything, I thank you again for your help.

Classic symptoms are water, mescla with oil, the oil is mesheed with water, the water enters the combustion camera, or the comprehensive is put into the water system. That usually there are very specific occasions where the packaging is blowing out and a noise is heard even to that of an elicopter or the compression is started from one cylinder to the other.

Thank you friend, it has more than clear that, it sounds like some call it bells, it seems to me that it is the last option that I have left to check so the problem must be there, it shall be there, there is no sign that a water is mixed with oil with oil. and all inside .. thanks friend for your time and your answers
