Vehicles using AM 473 engine list:

Engine AM 473, used in Maserati Biturbo 228 and 430 (1988–1991), commonly faces issues like overheating, oil leaks, and timing belt wear. Diagnose overheating by checking coolant levels, radiator condition, and thermostat function. Prevent overheating with regular coolant flushes and radiator maintenance. Oil leaks often stem from aging gaskets; inspect and replace valve cover and oil pan gaskets as needed. Timing belt failure risks engine damage; replace the belt every 30,000–40,000 miles and inspect tensioners. Regular oil changes with high-quality synthetic oil help maintain engine health. Addressing these proactively ensures reliability and longevity of the AM 473 engine.
