7 known faults with sources
Engines: 1.0 / 1.2 VTi (Petrol)
Applies if: Only the first generation with the Toyota 1.0 engine (1KR-FE).
Water pump and clutch on the 1.0 VVT-i (1KR-FE)Cooling
- Engine / equipment
- 1.0 VVT-i three-cylinder (1KR-FE): Toyota Aygo, Yaris and iQ, Peugeot 107 and Citroën C1
- Period mentioned
- Approx. 2005–2011
- Symptoms
- Coolant loss with coloured residue next to the pump and rising temperature; a clutch that slips or squeals and hard gear changes earlier than normal.
- Possible cause described
- In the early years the water pump often failed after about three years of use; it was improved in 2009. The original 180 mm clutch was short-lived; a larger one was fitted from 2009 (a 190 mm alternative exists). The German Yaris II guide also lists faulty water pumps on the 1.0.
- Check for the garage
- Look for dried coolant residue under the pump and watch the level. Test the clutch pulling away on a hill; if it is replaced, ask for the improved version.
- Cost cited in the source
- Approx. €300–550 for the water pump (German used-car guide).A rough figure from the original database, not an up-to-date quote.
