有些車主會因為發動機溫度高而盲目拆除節溫器，這樣做的話，使得冷卻液只能進行大循環，不能調節冷卻強度，難以發動機在較適宜的溫度下工作，反而使發動機經常處于低溫狀態下工作，造成發動機功率下降，磨損加快，油耗增加。
Some car owners will blindly remove the thermostat because the engine temperature is high. If they do so, the coolant can only carry out large circulation and can not adjust the cooling intensity. It is difficult for the engine to work at a more appropriate temperature. On the contrary, the engine often works at a low temperature, resulting in reduced engine power, accelerated wear and increased fuel consumption.
正確做法：如果發動機節溫器發生故障檢修或更換之后，發動機溫度還高，就應檢修冷卻系統的其他部位。
Correct practice: if the engine temperature is still high after troubleshooting or replacement of the engine thermostat, overhaul other parts of the cooling system.
第二個：發動機溫度怕高不怕低
Second: the engine temperature is afraid of high and not afraid of low
當發動機經常處于低溫狀態下工作時，會造成發動機功率下降，磨損加快，油耗增加。
When the engine often works at low temperature, it will reduce engine power, accelerate wear and increase fuel consumption.
東莞奔馳配件廠建議：應根據汽車使用說明書規定的正常溫度行車，以發動機的使用壽命。
Dongguan Benz parts factory suggests that the vehicle should be driven according to the normal temperature specified in the vehicle operation manual to ensure the service life of the engine.
第三個：水泵風扇皮帶越緊越好
Third: the tighter the water pump fan belt, the better
當皮帶過緊不僅會使其拉長或斷裂，縮短皮帶的使用壽命，而且還會因拉力過大，導致發電機軸、水泵軸變形彎曲和軸承的早期損壞。
When the belt is too tight, it will not only lengthen or break and shorten the service life of the belt, but also lead to deformation and bending of generator shaft and water pump shaft and early damage of bearings due to excessive tension.
建議：汽車發動機風扇皮帶的松緊度應符合技術要求，一般正常皮帶裝配時撓曲度為10-15mm為宜。
Suggestion: the tightness of automobile engine fan belt shall meet the technical requirements. Generally, the deflection during normal belt assembly is 10-15mm.
第四個：發動機用怠速升溫
Fourth: warm up the engine at idle speed
當發動機用怠速升溫時，由于轉速較低，機油泵不能較快地將潤滑油壓入各潤滑表面，油壓也低，使發動機各運動機件在干摩擦或半干摩擦狀態下工作;燃油因低溫霧化不良，使未燃燒的燃油(混合氣)竄入曲軸箱，沖刷掉缸壁上的油膜，也會加速機件的磨損。
When the engine is heated at idle speed, due to the low speed, the oil pump can not quickly put the lubricating oil pressure into each lubricating surface, and the oil pressure is also low, so that all moving parts of the engine work under dry friction or semi dry friction; Due to poor low-temperature atomization of fuel, unburned fuel (mixture) rushes into the crankcase and washes off the oil film on the cylinder wall, which will also accelerate the wear of parts.
建議：當發動機啟動數秒后，應用快怠速升溫，改善發動機的潤滑條件。
Suggestion: when the engine is started for several seconds, apply fast idle speed to raise the temperature and improve the lubrication conditions of the engine.
第五個：用噴燈烘烤油底
Fifth: bake the oil pan with a blowtorch
很多車主在冬天的時候，喜歡用噴燈烘烤油底，這樣做不但會使機油中的添加劑發生化學變化，失去原有的性能，而且還會使機油膠結、油底變形，容易引起火災。
Many car owners like to bake the oil bottom with blowtorch in winter. This will not only make the additives in the engine oil chemically change and lose their original performance, but also make the engine oil cemented and the oil bottom deformed, which is easy to cause fire.
