0.8 / 1.0 / 1.2 S-TEC vs 1.2 8v: which engine is more reliable?
According to our risk index, the 0.8 / 1.0 / 1.2 S-TEC carries less risk than the 1.2 8v: 18/100 (low risk) versus 36/100 (moderate risk). The 0.8 / 1.0 / 1.2 S-TEC has no documented serious faults; the 1.2 8v has 1 documented serious fault, the main one being «Damaged cylinder head gasket (coolant loss and overheating)».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 0.8 / 1.0 / 1.2 S-TEC reliable?
The GM Daewoo S-TEC engines (0.8, 1.0 and 1.2 naturally aspirated, low power) power the Matiz, Spark, Aveo 1.2, Beat and Sail. The sources consulted document only minor and cheap faults, such as oil leaks and ignition faults on the Matiz, and we have found no structural engine fault.[1][2][3]
See the 2 of the 0.8 / 1.0 / 1.2 S-TEC faultsIs the 1.2 8v reliable?
The 1.2 8v (D7F) is a simple naturally aspirated engine of 54 to 60 hp, with a timing belt, which Renault fitted from 1996 to the Twingo, Clio II and Kangoo. No catastrophic failures are documented; what owner reviews mention most often are the sensors, the cylinder head gasket, the coil packs and the occasional oil drip.[4][5][6]
