93年的车，16万多公里。前几天打方向盘时，一到极左或极右位置，就发出“吱吱”声。（是否方向不应打太大？） 现在的情况是，即使方向盘回正后，“吱吱”声依然存在，而且怠速状态下将油门踩大，汽车前盖发出“劈啪”的响声；打开前盖检查，发动机上那根最大的皮带已经发生局部破裂（肯定是踩油门造成的）。问题是：此皮带只与发电机相连，助力转向泵是由另一根皮带驱动的，那么如何解释这一切？问题严重么？刚买的二手车，就出问题，我该怎么做？心焦。谢谢大家指教！

Thanks so much! My friend has just check it for me, and even drove the car to a garage nearby to replace the belt. But unfortunately it was closed. He told me it's not serious, but I need to replace it ASAP, just like you have said. Now I feel better, and it reminds me to have my car inspected thoroughly. I will inform any further development, as a thanks to Mr.DonCherry.

You should go to the garage IMMEDIATELY. Break down on the street
is better than break on the highway. If you are not sure, just ask a
friend with CAA card to go with you on the way to the garage. when
it break,  you lost the electricity, you need towing any way.

感谢DonCherry！这么快就回答我。
具体情况是：问题正好发生在我们要出行时，所以现在还在门前停着。皮带只是破裂，还没有断（但不知能否再次启动？）先前，朋友检查说发动机和变速器良好，而且车主一直开着，上周才过的户，在我门前停了整一周，其间还绕附近街区转过。过程：发动机在“吱吱”声下怠速工作30分钟-->踩大油门-->立刻发出“劈啪”响声-->立刻检查，发现而皮带破裂。能否给个联系电话？

问题严重么?

No,  just ask CAA or and towing service to tow you car to garage and install
new belts.Belt cost (ps belt and alternator belt)for $10 ~20,  need 30min labor.


One thing is weird, why it broke when you press the gas peddle. How long you
  drive the car? Did it already break when you bought it? If so, you should ask the
previous owner to fix it.
