1、夏季行车注意事项夏季高温、多雨,是车辆安全事故多发的季节,现将相关事宜通知如下:Hightemperatureandrainydaysmakesummertheseasonwhenalotofvehiclesafetyaccidentshappen,therelevantmattersareherebynotifiedasfollows:一、防机体过热:夏季环境温度高,发动机容易过热。因此,夏季应加强对发动机冷却系统的检查、保养,及时清除水箱、水套中的水垢和散热器芯片间嵌入的杂物;认真检查节温器、水泵、风扇的工作性能,损坏的应及时修复,同时注意调整好风扇皮带的张紧度;及时加注冷却水。当
2、水温超过100℃时,应在荫凉处停车降温,让发动机怠速运转,并掀开发动机罩以利散热。当水箱开锅、发动机过热时,切勿将发动机熄火(电机驱动风扇的除外),也不可向发动机泼冷水,以防机体炸裂。Ruleone,preventoverheating:thehightemperatureoftheenvironmentinsummer,theengineiseasytooverheat.Therefore,insummer,weshouldstrengthenthecheckingandmaintenanceofenginecoolingsystem,andtimelyremovethescalei

6、失灵。因此,夏季应及时检查调整制动系统,及时添加或更换制动液,彻底排净液压制动系统中的空气,并保证制动皮碗、制动软管和制动蹄片的完好,行车中如发现制动踏板变“软”时,应及时排气;下长坡途中应注意停车“晾”刹,保证制动性能良好;若发现制动毂发烫,应停车降温,但不可浇泼冷水,以防制动毂破裂。Rulethree,preventbrakefailure:brakefluidinthehightemperatureenvironmentiseasytoevaporate,formairresistanceinthebrakepipe,brakeshoeisalsoeasytoablate,res
