一、冷却系不要缺水当冷却系有漏水或填加不足时,水位低于节温器高度时,节温器处于“干碗”状态。节温器内无热水,受冷风影响温度很低,无法使节温器通大循环水路。(节温器开通大循环的水路温度一般在75℃左右)。冷却系大循环被“旁路”,处于小循环状态,散热器成为死水“半潭”的容器。在严冬,散热器由于得不到热水取暖,加上受到风扇吹来的大量冷空气,致使散热器里的水冻结。水结冰以后体积增大,最后将散热理管涨。缺水的前兆是水温偏高。当完全打开百叶窗时,温度仍不下降,就要立即停车检查,如缺水要马上填加,并把百叶窗完全关闭,让发动机怠速运转,直到机体的热水将所有的散热 First, the cooling system do not lack of water When the cooling system is leaking or insufficient fill, the water level below the thermostat height, the thermostat in a “dry bowl” state. There is no hot water in the thermostat, the temperature is very low due to cold wind, and the thermostat can not pass the large circulating waterway. (Thermostat opened the general circulation of the water temperature is about 75 ℃). The cooling system was “bypassed” and circulated in small cycles. The radiator became the “half-pool” of stagnant water. In the severe winter, the radiator is not hot water heating, plus a large number of cold air blown by the fan, causing the water in the radiator to freeze. Ice after the volume increases, and finally heat management up. Water shortage is a precursor to high water temperature. When the shutters are fully open, the temperature still does not drop, it is necessary to immediately stop inspection, such as lack of water to immediately add, and the shutters completely closed, let the engine idle speed until the body’s hot water will all the heat
