Vehicles using HD-E engine list:

Engine HD-E commonly faces issues such as valve wear, oil leaks, and timing belt degradation. Diagnosis includes checking for unusual noises, oil consumption, and timing belt condition. Preventive maintenance involves regular oil changes with quality oil, timely replacement of the timing belt (typically every 60,000–90,000 km), and inspecting valve clearances. Solutions for valve wear may require valve adjustment or replacement. Address oil leaks by replacing gaskets and seals promptly. Ensuring the cooling system is functioning well prevents overheating, which can damage the engine. Regular maintenance and attentive monitoring extend the HD-E engine’s reliability in Daihatsu Applause and Charade models.
