Head Gasket Replacement Cost
RepairPrice Estimates are based on the estimated time for the repair, labor rates charged by trained automotive professionals, and prices for quality parts.
These estimates are designed to show a range of fair prices, instead of a single price, because there is more than one part that is appropriate to use in each repair, and more than a single mechanic who is qualified to do the repair.
Each estimate is customized for your vehicle and geographic area. Estimates exclude applicable taxes, diagnostic charges and disposal fees.
Head Gasket(s) Replacement Estimate (National Average)
To prevent an expensive, recurring problem, the integrity of the entire cooling system should be inspected and tested when a head gasket is replaced.
During this repair, the cylinder head(s) will need to be inspected and machined. Additional repairs may be needed after the inspection, which can add several hundred dollars to the repair and are not included in the RepairPal estimate.
Cylinder head gasket replacement often occurs when the engine has high mileage; several additional parts may 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.
Head gasket failures are often due to an overheated engine, but can also be caused by high mileage and/or age.
An early sign of a failing head gasket will be a rough running engine when you first start the vehicle, especially if it's been sitting overnight. The rough running will generally last for only a few seconds.
A leaking headgasket 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 can produce a white, sweet-smelling smoke from the tail pipe.
