Engine Overview and Common Failures
The weight of the 5E-FE engine according to the catalog is 115 kg. The engine number 5E-FE is located at the junction of the block with the cylinder head. Overheating is the most common engine failure, resulting in a blown cylinder head gasket. Due to the same reason, seals can become stiff and leak, so make sure to monitor the cooling system. Another common issue is excessive oil consumption, which usually starts after 150,000 km. The culprit is usually worn piston rings and oil control rings. This engine does not tolerate low-quality fuel, as it quickly clogs the fuel injectors, deposits carbon on the throttle body and intake manifold, and the engine starts running unstably. The timing belt is supposed to last for 100,000 km according to the schedule, but often stretches significantly earlier. It's fortunate that when it breaks and the valve interference occurs, the engine rarely bends valves. Among minor but frequent breakdowns are malfunctions in the ignition system components, oil leaks, limited lifespan of some sensors, and primarily the lambda sensor. Additionally, this engine does not have hydraulic compensators, so the valve clearances periodically need adjustment.
