一辆捷达乘用车,在行驶14万km后来我厂检修,技术人员发现其正时带已严重老化,建议车主更换正时带。当时车主为了省钱而不愿更换,以致正时带在乘用车以后的一次起步加速时突然断裂,该车又一次被送到我厂维修。技术人员认为,正时带的突然断裂极有可能使发动机产生“内伤”,如果只更换正时带和重新校对点火正时,恐怕不仅不能从根本上修复发动机,而且还会使让人担心的“内伤”扩大,给车 A Jetta passenger car, traveling 140,000 km after I plant overhaul, technicians found that the timing belt has been seriously aging, it is recommended to change the timing belt owners.
