Most common problems, symptoms & fixes for the G4EK engine.

Engine G4EK commonly faces issues like timing belt wear, coolant leaks, and ignition coil failures. For diagnosis, regularly inspect the timing belt for cracks or slack to prevent engine damage. Check for coolant leaks around the radiator and hoses to avoid overheating. Misfires or rough idling often indicate faulty ignition coils, which should be tested with a multimeter. Preventive maintenance includes timely timing belt replacement (every 60,000-90,000 km), regular coolant flushes, and spark plug inspections. Solutions involve replacing worn belts, repairing leaks, and swapping out defective ignition coils. Keeping up with scheduled maintenance ensures engine longevity and reliable performance.
