Periodic temperature loads have an adverse effect on the drive unit. Even if it’s completely right. And when, after frost, the thermometer column “creeps” to the “positive” zone, the engine may not start. The AvtoVzglyad portal tells why this is happening and how to avoid serious consequences.
Positive temperature for a car is a decrease in wear and load, but high humidity does not bode well. With sudden changes in temperature, water appears on the battery terminals and other electrical contacts, causing a short circuit. This can lead to increased self-discharge currents of the battery. That is, the car simply does not start.
Moisture also accumulates on the internal parts of the drive unit. Especially if the car rarely leaves and spends most of its time on the street. The fluid, together with air, enters the engine through the intake tract, after which it condenses on the walls of the cylinders.
Add to that the fact that the lubricant for about five days of parking thickens the window in the crankcase. It turns out that in the first seconds after starting the engine undergoes huge loads and works in the most severe oil starvation mode. The thickness of the protective film on rubbing parts is insufficient and the lubricant is mixed with moisture particles.
Strong wear is also brought closer by small runs, during which the car does not have time to fully warm up. Then scuffs appear on the walls of the cylinders, which eventually become palpable.
Further. The so-called condensate emulsion occurs on ignition coils and high voltage wires. Therefore, often even in motion, the “heart” of the car runs unevenly, and the speed “floats”.
Fluid can also get under the distributor cover. If it is near the runner, it will affect the launch of the power unit and it will also “struggle” all the time.
What to do in this situation? It’s best not to hit the road – much to Deptrans’ delight. Since the laws of physics cannot be revoked, water will still get into the engine and do its dirty work there. It is better to use a taxi or car sharing. You can not feel sorry for the rolling “iron horse” at all.
