Vehicles using ARK engine list:

Engine ARK commonly faces issues like turbocharger wear, oil leaks, and timing belt tensioner failure. Diagnosis should start with checking for turbo lag or unusual noises, inspecting for oil leaks around the turbo and valve cover gasket, and verifying timing belt condition. Preventive maintenance includes regular oil changes with high-quality synthetic oil, timely replacement of the timing belt and tensioner (every 60,000-90,000 km), and ensuring the cooling system is functioning properly to avoid overheating. Solutions involve replacing worn turbochargers, renewing gaskets to stop leaks, and changing the timing belt and tensioner to prevent catastrophic engine damage. Regular inspections help maintain engine longevity.
