来自主题: Automobile版 - 漏了冷却液
今天开车时突然听到引擎有个响声,还以为是有小石子砸到了。在停车场放了一会儿,
就发现车底下漏了一滩液体。打开引擎盖,发现coolant已经干了。
于是买了一瓶distilled water灌满又开回家 。好在水箱温度一直显示正常。
仔细看了一下,发现在gasket的侧面就有绿色的冷却液漏出来了。请问这种情况,修的
话会不会很贵啊。谢谢!

至于面试我准备的50多个问题。我的想法是一定要站在学校的角度思考问题。很多问题
太个性化,并不适用于大家。我把能分享的答案分享,很多也是在网上找的答案。
1. What made you apply for this position?
Why do you want to work here?
Everyone has strengths and weaknesses as employees. What are your strong
points for this job?
What special aspects of your education or training have prepared you for

you need to know what kind of leather you have, generally, protected or

cleaning. Use just distilled water for the first round is not a bad idea.
if it's kind of dirty, then use a little bitter soapy water (just ivory soap
). then you need apply leather conditioner.
the best brand is leather master, there are many alternatives out there.

“Experiments in animals, primarily rats, for up to one-year periods have
repeatedly shown that the intake of distilled water or water with TDS ≤ 75
mg/L leads to: 1.) increased water intake, diuresis, extracellular fluid
volume, and serum concentrations of sodium (Na) and chloride (Cl) ions and
their increased elimination from the body, resulting in an overall negative
