How long,under mormal driving, will the overdeah cam belt last?
Well , you should have proof read your post . But I am guessing you mean the timing belt or the serpentine belt. If you do have a timing belt your manual will say change it at xxxxx miles or xxxx months. Serpentine belts last a long time .
From a Cruz owner that actually read his owners manual;
2014 CTD says 10 years or 97000 miles. Whichever comes first.
