1.6 Twinport / XER (Z16XEP, Z16XER): timing belt at 150,000 km / 10 years

critical

The 1.6 naturally aspirated petrol engines of the Astra H (Z16XEP, Z16XE1, Z16XER) run a timing belt, not a chain. The replacement interval is 150,000 km or 10 years, whichever comes first.

Show the rest

If the belt breaks, the engine is badly damaged inside. Most used cars are right around the 10 year mark, and if there is no invoice for the belt change, the belt is due.

On the Z16XER the variable valve timing (phaser and solenoid) can rattle on a cold start, and it can log a P0011 or P0014 fault code. That is not the belt.

between 120,000 and 180,000 km

What to check

  • Ask for the timing belt replacement invoice: 150,000 km or 10 years, whichever comes first
  • If there is no documentation and the car is over 10 years old or above 150,000 km, count on a belt change
  • On a cold start listen for the phaser rattle: it is not the sound of the belt, but it is common on this engine

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
