Vehicles using ARU engine list:

Engine ARU commonly faces issues such as oil leaks from valve cover gaskets and timing chain tensioner wear, leading to rattling noises. Diagnosis involves checking for oil seepage around the valve covers and listening for unusual engine sounds at startup. Preventive maintenance includes regular oil changes with high-quality synthetic oil and timely replacement of timing chain components around 100,000 km. Solutions for leaks involve gasket replacement, while timing chain tensioner issues require component replacement to avoid severe engine damage. Additionally, monitor coolant levels to prevent overheating, and inspect ignition coils periodically to maintain smooth engine performance.
