Could this be the end of the Astra?
Safety warning: Holden Astra, Vectra and Barina
Camshaft drive belt (cam belt) and cam belt drive sprocket fitted to Holden Astra, Vectra, or Barina cars.
The cam belt on many Holden Astra, Vectra and Barina cars is liable to fail much earlier than expected. This is often due to a fault with the crankshaft sprocket. If the car's cam belt fails, the engine will suffer very severe damage.
Holden Astra, Vectra or Barina cars which are more than four years old or have travelled more than 60,000km, should have the camshaft drive belt (cam belt) replaced immediately. The cam belt drive sprocket on the end of the crankshaft must be checked, and if faulty replaced (unless this has already been done).
All associated pulleys and the water pump must be checked and replaced if there is any doubt about their condition.
Models most at risk
Holden Barina 1.6 litre engines, from 1994.
Holden Astra 1.6 and 1.8 litre engines, from 1995.
Holden Vectra 2.0 and 2.2 litre engines, from 1994.
What to do
Contact your nearest Holden dealer (see "car dealers" in the yellow pages) for advice if you think your Astra, Vectra or Barina has not had its cam belt changed. Don't drive the car until you are sure it is safe to do so.
