Is the 1.8 and 2.0 Zetec-E reliable?

The 1.8 and 2.0 litre Zetec-E engines in the Focus I are simple naturally aspirated petrol engines that, according to the sources, have no recurring serious fault. The most frequently mentioned issue is the plastic thermostat housing, which deforms and leaks coolant; in addition, Ford issued a recall in 2000 to replace the oil filler cap on 1.8 and 2.0 units built up to December 1999.[1][2][3]

Is 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]
