Cylinder Head Replacement Cost
Cylinder Head Replacement Estimate (National Average)
Cylinder head or head gasket replacement is a large, time-consuming repair that often occurs when the engine has high mileage and/or the engine has been overheated. Due to these conditions several additional parts will be needed during the repair. These may include cooling system components (hoses, water pump, radiator, thermostat, etc.) vacuum lines, timing belt, ignition wires, and more. These will be in addition to the RepairPal estimate above.
To prevent an expensive, recurring problem, the integrity of the entire cooling system should be inspected and tested when a cylinder head/head gasket is replaced due to overheating.
A leaking head gasket or cracked cylinder head will often leak engine coolant into the oil, causing a "chocolate milk" like appearance and the oil level my be higher than normal.
Failed head gaskets or damaged cylinder heads can cause engine coolant to leak into the combustion chamber, producing a white, sweet-smelling smoke from the tail pipe.
