I have cooling system problem

Hello, someone can help me I have a problem with my car's cooling system, the very fast antifreeze is over and the fans are able to heat if they work well only that the antifreeze does not last long and does not have a trace of oil the oil of the antifreeze that could be if someone can help me I will appreciate it very much since I really want to learn everything about mechanics grace

Look do not have a liquid leak some side

The one that you have a leak is quite clear, the antifreeze does not disappear by infusa science \ "now the subject is to know where you are getting.

First, examine all pipes and sleeves in search of evaporated antifreeze traces, these traces are like ranch or scabs of the color of the antifreeze. If you find nothing with the naked eye, you have to make a fairly simple user.

The user consists of a cork or rubber cap that can pressure the expansion vessel. This plug must carry a little hole for which you go to put air under pressure (eye never more than 1 bar).

Once the tool is made, and with the standing and cold engine you introduce the tool instead of the expansion vessel cap and put air, the air goes to force the liquid to look for the exit and immediately you will detect the leak since the cold antifreeze does not evaporate.

If the antifreeze is not out anywhere, the leak can be on the same expansion vessel cap that does not maintain the pressure causing the water to boil and leave or in the worst case by the butt joint, so that the liquid would sneak into the cylinders, in that case the engine would fail to slow black carbonilla remains.

All the best.

Certainly with a leak analyzer, you connect it instead of the radiator plug and you put 15 psi and observe where the antifreeze comes out; It is also important to check the color of the smoke a color with a white nuance I would indicate that the antifreeze is going to the combustion camera and that is why you are losing antifreeze, in that case it could be the board of the head and there would be spots of the antifreeze in the monoblock; In the worst case it could be that the head already has cracks and would have to change it or that for wear through one of the monoblock shirts the antifreeze is filtered and in which case it would have to be considered a rectification if the monoblock allows it
