Sometimes cooling liquid in the cooling system can leads to engine overheating and other unpleasant consequences. It is always important to have the necessary knowledge to carry out the proper maintenance of the engine and fix such problems. To do this, you need to be able to quickly and correctly identify the cause of the leak and always have the right equipment to eliminate it.
The most important device for troubleshooting is the temperature indicator. Unfortunately, most cars are not equipped with a signal warning of the temperature outside the permissible regime. When boiling, the coolant can disable the whole system. The resulting vapor prevents normal cooling of the power unit, the temperature begins to arrive at a tremendous rate.
Just a few minutes of driving with an overheated motor, can disable it and no auto cosmetics will help even if you get mitsubishi lancer or another reliable car.
The head of the block is deformed and the piston group sometimes gets stuck with a break of connecting rods. Another reason for overheating may be a fan, although it is a reliable device, which cannot be said about the temperature sensor and the relay.
Care of the engine begins with the inspection of the fuse. The fuse box cover usually contains a pictogram indicating which fuse is responsible for the fan. There are situations when it needs to be simply replaced. Also do not ignore the temperature sensor. Find it will not be very difficult, since this is a unique radiator part, with outgoing wires. They must be disconnected and closed between each other, only then turn on the ignition. In the event that the fan is working, it can be concluded that the sensor is defective. You will not be able to repair it, however there is a chance to continue the movement, leaving the wires closed, and the fan continuously working.
It happens that even this does not help, then you need to remove the relay from the system. It is necessary to get it out of the safety box, jumpering the nests with a piece of wire of the control contacts. Sometimes it does not work, then it should be checked if there is power in the motor part of the fan, to which help the control lamp will come. If there is no power, and the light does not come on when the ignition is switched on, the problem is in the wiring. In this situation, the most reasonable thing is to use a piece of wire, and the power to the fan will be fed directly from the battery.
If the fan voltage still exists, the electric motor may have failed. In this case, it remains to continue the movement, but do not forget to observe the indication of the temperature indicator. As soon as the arrow starts to approach the red zone, immediately stop, open the hood and cool the engine.
Sometimes the cause of overheating can be the thermostat. In the closed position, the device can sometimes wedge, and the coolant will circulate around the radiator. When the motor is hot and the radiator is cold, the thermostat is closed. It is possible that it will be enough just to knock something on the thermostat case and it will open. If the thermostat is faulty, the best solution is to replace it as soon as possible, by the way it is written in the instructions for caring for the engine. Even if this option does not help, then the thermostat will need to be removed. The procedure requires sufficient effort, because it is necessary to break the entire filling out of the removed thermostat and only after that it can be put in place. The spare parts for your car you can easily find on the sites selling everything for the cars and where you can check BMW 328i offers and find necessary stuff for your engine.
And remember that the correct and timely maintenance of the engine of the car will prolong its life and reduce the likelihood of breakage on the road.
