Coolant leak is one of the most common causes of engine overheating. That is why it is necessary to know how to identify the problem in time and how to cure it. Unfortunately, many drivers check only the speedometer. However, one of the most important control panel indicators is a water temperature gage. In most of the cars it is not equipped with warning signals and by the time the driver scent a strong smell of antifreeze and notices the steam from under the hood the car will probably need a serious repair.
The cooling system of an engine is designed as a sealed system with engine coolant held under pressure. When boiling the coolant stops proper cooling of the power unit and the temperature starts to grow rapidly. Few minutes of driving with an overheated engine can cause either a cylinder head deformation or a piston block self-locking with a breakage of con-rods. Be very careful when working on the cooling system. When hot it is under pressure and can cause extreme burns if opened when it is hot. Also be careful when working around hot or rotating engine parts. Ici you can find anything you need for your car.
Another common cause of engine is electric cooling fan. Ensure the fan clutch is operating properly. Ask an assistant to turn the engine off while observing the fan. It should only spin for about 2 seconds after the engine is shut off. If the fan continues to spin for several seconds after the engine is shut off and the engine only overheats at low vehicle speeds, then fan clutch replacement may be necessary.
Although the fan itself is reliable enough and rarely breaks down, the problems are usually caused by a temperature sensor and relay. An operation mode of fan is simple: as soon as the coolant temperature rises to a certain extent, the sensor closes the control relay turns on a fan. If not, then check the fuse. Usually, a pictogram on its cover block shows the one that concerns a fan. Sometimes it looks fine, but doesn’t engage due to bad seating. If the fuse is blown, then, it should be replaced.

The next step – check the temperature gage. It is the only part of the radiator that has outer wires and therefore, is easy to be found. Unhook them from the gage and hook to each other, then start up the ignition. If the fan starts spinning, then the sensor is broken. It cannot be fixed; however, you can drive further, leaving the wires hooked and the fan running.
