Aluminum alloy cylinder heads are lighter and offer better heat dissipation, improving engine efficiency and performance. Cast iron cylinder heads are more durable and cost-effective, with better wear resistance for high-stress applications.
Common signs include engine overheating, loss of coolant, white smoke from exhaust, misfiring, and reduced engine power. These often indicate cracks, warping, or gasket failure in the cylinder head.
Regular maintenance includes checking for leaks, ensuring proper torque on head bolts, monitoring coolant levels, and inspecting valve components for wear. Periodic valve adjustments and decarbonization may also be necessary.
