Identifying a Cracked Cylinder Head: Common Symptoms

DIY Repair vs. Professional Help: How to Fix a Cracked Head on a Car

Repairing a cracked head is a complex and time-consuming job. It involves removing the cylinder head, having it inspected and possibly repaired or replaced, and then carefully reinstalling it. While a DIY approach can save money, it requires advanced mechanical skills and specialized tools. In most cases, seeking professional help is the recommended course of action.

Repairing a Cracked Cylinder Head: Steps Involved

4. Reassembly: Clean all mating surfaces and install a new head gasket. Torque the head bolts to the manufacturer’s specifications.

5. Refill and Test: Refill the cooling system and check for leaks. Run the engine and monitor its temperature.

Cost of Repairing a Cracked Head

The cost can vary significantly depending on the make and model of your car and the extent of the damage. Expect to pay anywhere from $1,500 to $3,000 or more for a professional repair. Sometimes, fixing seemingly minor issues can have a hefty price tag, such as 5 000 to fix oil leak in car.
