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

Engine AEH is known for timing belt wear and potential tensioner failure, which can cause severe engine damage if neglected. Regular inspection and replacement of the timing belt and tensioner every 60,000 to 90,000 km is crucial. Common issues include oil leaks from camshaft or crankshaft seals; replacing seals promptly prevents further damage. Misfires may occur due to faulty ignition coils or spark plugsβ€”routine checks and replacements help maintain performance. Cooling system maintenance is vital to avoid overheating; regularly check coolant levels and radiator condition. Using quality oil and timely oil changes prolong engine life and reduce sludge buildup.
