Every novice driver during his training heard a hundred times no less terrible stories about how a car engine breaks down. At first, it seems that the motor can become unusable from any movement. Still, gradually, the understanding comes that the engine is just an auto part that breaks down for only one reason: improper use. If you are a careful driver who passes all technical inspections promptly, the engine will not fly. Let’s consider the most terrible, deadly situation for the engine when motors die.
The coolant temperature sensor can “crawl” into the dangerous red zone or pour steam from under the hood …
It looks very scary, but, as a rule, everything can be fixed on the spot. There are many reasons why the motors die, but only three are most common: hot weather, lack of antifreeze, and long driving in low gears. The engine is the most durable and reliable thing, but with a certain “zeal,” it can also “die””. The motor can withstand very high temperatures but also has a certain margin of safety. An engine can burn out for a variety of reasons.
- Cooling system failure. Damaged fan blades, torn belts – all this can cause the death of the motor. Likely, the cooling system is worn out. Its service life can be very impressive, but if you use it “both in the tail and in the mane” or use water instead of a special liquid, it will quickly become unusable. A coating of dirt and soot will appear in all its parts, subsequently becoming the main cause of damage to the motor.
- Bad gasoline. Prolonged use of low-quality fuel can easily damage the engine. The fuel will burn for too long, which will “kill” the engine.
- Incorrect motor setting. Failures in the ignition system often cause engine failure.
- “Full throttle” and first gear. This is what all instructors most often swear at novice drivers. Of course, you can ride like that for a very short time. In this case, the motor operates under conditions of increased loads. Naturally, after a few months of such trips, the motor dies from “overvoltage”.
If the engine has received a serious “thermal stroke”, this can lead to the fact that the pistons will also overheat under the pressure of temperatures or even completely: burn and melt. Replacing pistons is, of course, sad, but not too much. But if you do not turn off the engine with melting pistons, you can bring the car to a complete engine replacement.
You were driving calmly over rough terrain, and suddenly, noise, clang, rattle from under the hood. The engine stopped working…
If, before the breakdown, the motors die made an uncharacteristic roar for it, then it is likely that the problem was in the valves. As always, the cause of valve problems: is improper vehicle maintenance.
- The valve may be wedged due to high temperatures in the engine. The blame for everything is the same notorious overheating.
- The cause of the tragedy is likely a broken spring, due to which the valve ended up inside the cylinder.
- Another cause of the valve problem is the tightness of the driver. When using low-quality engine oil and bad fuel, a lot of dirt and coke gradually accumulate on the valves, ceasing to function properly. The result of such “savings” is either a very expensive repair or a complete replacement of the motor.
- By the way, the valves can tap and “toss” the car on the road due to the “cold running””. If you have the habit of starting the car immediately in winter, without warming the engine for a minute, this will always happen. With this approach, the engine cannot be seen for long life.
There was a rotation of the bearing shell, and the shaft was wedged. There can be many reasons for this, but, by and large, they can be divided into two broad categories.
And the motor refused you completely and categorically. It does not work, and not a single mechanic can already help …
- Oil shortage. A fatal and catastrophic lack of oil in the motors die leads to the fact that some parts of the engine are no longer lubricated completely, which invariably entails turning the bearing shell. The car may have been running out of oil for three hundred years, but this rarely happens. More often, the cause is a breakdown of the oil pump itself, which has stopped supplying lubricant to the motor. The unexpected transformation of the oil into a tarry mass unsuitable for the engine can be attributed to the same category. The result of an oil shortage of this magnitude: a crank and a wedge. Well, then, only a major overhaul at the cost of a new car. There are several reasons why solid oil can be found in the engine:
- Incorrect application. If you use summer lubricant in the cold season, then most likely, the oil will thicken and lose its properties.
- Poor quality lubricant. You should not use very cheap oils purchased from an unverified manufacturer. Such a lubricant can easily turn out to be a bad, low-quality product that will ruin your engine.
- Untimely oil change. Gradually, the lubricant loses its properties, and a huge amount of impurities accumulate. Gradually, the oil turns into a plastic mud lump.
