Condensation in the vehicle can cause damage to the vehicle. Especially in the winter season. Condensation occurs almost constantly in various car systems: in the lubrication, power, cooling and exhaust systems. In addition, condensation accumulates in the passenger compartment and in closed body cavities.
Condensation begins to accumulate in the muffler immediately after the engine stops. This happens because the outside of the system cools down much faster than inside. Therefore, water droplets quickly begin to accumulate inside the exhaust pipe. In winter, after a few hours, they freeze, and when the engine is turned on, water begins to drip from the pipe. Sometimes in large volumes. The amount of water generated depends on the characteristics of the operation. The more often you drive in cold weather and the more often you use autostart, the more condensation will accumulate in your car's muffler. Experts say it's not scary. On the contrary, the presence of condensation indicates that the engine is in good condition. Over time, however, this can cause internal muffler corrosion. In winter, during long-term parking, the muffler can freeze so that the car refuses to start. A whitish coating on the oil filler cap is also condensation. Formed as a result of water entering the oil system. When the engine cools down, water forms on the top of the engine and on the valve cover. After starting the engine, the plaque on the valve cover is washed off, but remains on the oil filler cap. In most cases, the amount of water in the oil is the smallest and does not affect the quality of the oil. But there are cases that condensation is formed as a result of damage to the cylinder head gasket and the ingress of coolant into the lubrication system. Usually this phenomenon is accompanied by overheating of the engine. In the gas tank, water can appear not only as a result of condensation. It can come in with fuel when refueling. Condensation appears on the inner surfaces of the gas tank when the car is parked in warm rooms, and the amount of fuel in it is small. The less it is in the tank and the greater the difference between the outside temperature and the temperature in a warm garage, the more water will condense in the tank. Over time, water, mixing with fuel, leads to interruptions in the operation of the fuel pump and spark plugs. In diesel engines, condensation leads to freezing of fuel hoses and a fine filter in the winter season. Condensation in the internal cavities of the body also forms when the temperature drops. In winter, this happens only when the car is stored in the garage, and in other seasons it does not even depend on this. In summer, for example, during the day, the sun heats up the body strongly, and at night it cools down, accumulating water droplets in closed cavities. When driving, condensation on the surface of the body dries quickly, but not inside. Therefore, if the anti-corrosion protection of the body is insufficient, it starts to rust. This is especially noticeable on doors and thresholds, inside which there are large closed cavities.
