The thermostat is an essential part of your car that allows the engine to operate at proper temperature all times. Its operation is very simple. The piea in question is at rest or closed when the coolant temperature is cold and opens, allowing the free flow of coolant, regulating engine temperature at an optimum point.

THE PROBLEM – Yeah, the problem arises when the damn contraption stops working, risking our engine. How do notice that the thermostat is not working? In my case, I started my car and I circulated for no more than about 10 minutes when I realized that the temperature is marked on the dashboard began to rise unchecked, the car did not respond well (due to recalentón) and had to stop and wait for it to cool. The issue happened to me near my city, so I could turn around, look for parking and park quickly, always avoiding the vehicle to overheat excessively.

After tracking by Google and after asking in various forums, my doubts were resolved. The problem was the thermostat, which is part (at least in my 1999 Seat Ibiza 1.4) at the end of the sleeve that goes from the radiator to the engine block. To verfificar that the problem could come from there, started the engine and waited until the temperature reaches the half normal engine working. It is then when the thermostat, due to the high temperature of the coolant must act and opened, allowing the movement of the same and to adjust temperature. However, my thermostat is not opening and the sleeve of the bottom of the radiator remained cold, while the other is placed at a very high temperature and showed how DASHBOARD and temperature was already over and spent half, which not recommended.

HOW TO REMOVE THE THERMOSTAT? To remove the thermostat we remove the two screws which secure the housing to the engine block, but EYE!Very careful here, because obviously, to get the thermostat the coolant will come out right there.

The first is to work with the   engine cold;

NO TIRES 2nd coolant to the ground, it is very toxic and harmful to the environment. In the case at hand, you can get a bottle of 5 liters of water cut in half (to fit) and tease out the liquid slowly and pass it to a big one for further use or recycling container.

3rd After removing the two screws holding the housing to the engine block, pull gently on the housing and then the damn thermostat appears. While the thermostat is highly recommended also change the cover or casing.

In my case, it was broken and could not open the thermostat circuit water. Also, do not forget to use a new gasket to prevent leakage from the lid, along with a new sleeve to securely fasten the bracket to the housing.

4th Once put everything in place, replace the coolant and do the test we did at the beginning to verify that the thermostat works, and once the temperature reaches half opens and allows the flow of liquid through the circuit . And with that you have your vehicle in condition for another seas
