Disadvantages of the Z32SE engine
- This motor does not like frost and not only starts poorly in winter, but also freezes on the go.
- But the main problems of the engine are associated with the low resource of the timing chain mechanism.
- The chain can stretch already on a run of 50,000 km, and the cost of replacement is not encouraging.
- The engine is afraid of overheating, when driving with a clogged radiator, rings quickly lie.
- The remaining breakdowns of the power unit are usually associated with oil leaks and ECU glitches.
