Petrol · 1,364 cm³ · 120, 140 hp · since 2008

Good choice, check first
Reliability
4.5/5

1 known fault

Verdict

A 1.4-litre turbocharged four-cylinder petrol engine from the Family 0 range, fitted to the Opel Astra J, Meriva B, Zafira Tourer and Mokka and the Chevrolet Cruze and Trax. Its recurring weak point is the cooling system: a plastic thermostat housing, water pump and expansion tank that leak. Check the coolant level and look for leaks; an untreated loss can lead to overheating.
