On the 2012-2019 Opel Mokka 1.7 CDTI (A17DTS), the 1.7 CDTI water pump is timing-belt-driven in this engine. When the pump seizes or its impeller fails, the timing belt can be ejected — leading to valve damage. Failure typically appears between 80,000-130,000 km, often before the recommended belt service.

This issue also affects: Opel Vivaro

Common Symptoms

  • coolant weep
  • belt area noise
  • sudden engine stall
  • no compression after pump seize

How to Fix

Replace water pump WITH timing belt as a kit (€700-€1,100) rather than belt alone. Catastrophic pump failure with belt jump means head rebuild (€2,500+). Do the kit early if there's any whining or weeping from the pump.
