两周前看过coolant液位还是够的,前天仪表显示发动机过热,而且闻到了糊味,立即停车,等车凉了,看到coolant 明显少了,可没见到有漏液的地方.加满coolant后,也没有漏液,跑了几次都没有过热,但是跑到10迈左右,发动机到radiator的管子只有一个是热的,另一个是凉的.又idle了一会儿,两个管子才都热了.是不是thermostat不够灵敏了?还是raditor需要flush?请各位大侠给指导一下,多谢.车是civic, 1993, 175k.

感谢大侠的指导。这两天的检查结果:coolant 明显少了,水泵处有漏液,但象是coolant 和一点点油的混合物。车尾没有白烟,机油没有milky,hose上没有液体。一个月前,我发现水泵处有漏液,送去check and pressure test,说没有问题。之后几天水泵处又没有漏液,我以为它好了,就没再管它了。结果就有过热的情况。是不是水泵坏了pressure test查不出来?head gasket 会有问题吗?多谢指导。
Engine Overheat Update, please help
