在您的问题中,您尚未说出您正在遇到的“错误”,因此我会认为它过热。如果没有,请用澄清回信,以便我们可以最好地为您提供帮助。有无数的原因过热,因此,确定车辆根本原因的唯一方法是拥有认证的机械师表演冷却系统诊断。Just to give you an idea of the extent of it, even potentially dragging brakes can cause overheating as can excessively lean engine operating condition (too much air, too little fuel) but it is common for thermostat to be stuck shut (and stuck open too, which degrades engine fuel economy), radiators to be partially blocked, hoses to be collapsed (blocking coolant flow), fans non functional, and water pumps that are not pumping at the design (required) rate. All of these potential faults, and others, would be ruled in or out during a冷却系统诊断。为了回答您的问题,是的,即使您的冷却系统没有泄漏,水泵也可能是无效的,因为泵驱动带缺乏张力和/或有时泵叶轮侵蚀或剪切。至于恒温器,通常会排除许多“外部”和明显的过热原因后,这​​通常是怀疑的。恒温器的寿命确实有限,实际上,每当在冷却系统上完成重大工作时,当然会作为预防措施和廉价保险进行更改。因此,如果事实证明您需要一个水泵,毫无疑问,一个好的机械师会建议您安装新的OEM(不是售后市场)恒温器。如果您有进一步的疑问,请告诉我们。如果您安排诊断,则经过认证的机械师将确定您正在经历的过热的原因。
