According to Goliath, a head gasket repair is the 7th most expensive automobile repair, and a new car will cost you far more.

This is why so many individuals opt to replace their head gaskets. How much does it cost to replace a head gasket once you’ve made the decision to do so?

According to the severity of the damage to the engine and other circumstances, the cost of a head gasket replacement might range from $1500 to $2,000.

It’s ironic, then, because the gasket itself is only $30 or so. At $100, the most expensive ones are high-performance ones.

In most cases, the only thing you’ll need to change is the gasket, which isn’t expensive unless you’re going with a copper gasket.

However, there are other variables that contribute to the cost. Not only did the gasket and the work cost money, but so did the damage to the engine as a whole.

On the condition that you get your car serviced regularly, the head gasket is expected to endure a long period.

On the other hand, typical wear and tear is not the only reason of a blown head gasket.

Extreme overheating, a lack of coolant, and even problems with combustion are among the possible causes.

The most expensive part of a head gasket replacement is labor, which can run up to $1500.

For this reason, the technician would have to disassemble the engine and reassemble it after replacing the head gasket in order to get to the part.

In addition, the camshaft is reset, and the timing gears are adjusted. The engine will only resume normal operation once you’ve completed these steps.

Because this is a time-consuming task, it will take at least 10 hours or more to complete.

In addition, the rates are based on the number of hours worked. Depending on where you live, the hourly charge might range from $75 to $125.

It’s also crucial to note that this isn’t done by your average mechanic. The service is done by specialized auto repair firms, and as a result, it is more expensive than your typical job.

A dealership or a reputable auto repair business is the best option.

You can’t always trust the parts used by unlicensed mechanics. However, they’re less expensive than a dealership or a repair shop. They’re cheaper.

What Can You Expect From Your Mechanic?

In what part of the engine does the head gasket need to be replaced?

Because it sits in between the engine block and the cylinder head, it keeps fluids and gases separate as they circulate.

An engine mechanic is not only responsible for replacing a blown gasket but also checking the engine for any damage that may have occurred.

He might inspect the cylinder head for distortion. He files it if it’s bent to make sure it’s flat. The gasket won’t fit properly if there isn’t a smooth surface, and fluids will leak.

The technician will also swap out the thermostat and perform a coolant flush in addition to replacing the cylinder head.

It would cost $50-$150 for the latter, and $30-$75 for the former, As an additional expenditure, he may also need to replace the gasket.

You won’t have to shell out a lot of money for a new head gasket, but there are also high-priced options available.

A typical gasket set includes the gasket, bolts, and other necessary components. The gasket is frequently all that is included in lower-priced gaskets.

Most repair companies include this in their pricing, so you won’t have to pay extra for it. However, if you’re curious about the pricing, request an itemized statement.

5 Factors That Impact The Cost Of A Gasket Replacement

Changing the head gasket on a car is a major undertaking, and it’s one that should be left to the professionals.

Having a blown head gasket can cause the engine to malfunction, which will lead to greater and more expensive damage over the years.

The urgency of the repair and the amount of the damage can have a significant impact on the replacement costs.

1. Age Of The Car

However, despite the fact that the head gasket is designed to survive for a long period, it will eventually wear out. Regardless of how long-lasting a component is, it will eventually succumb to wear and tear.

The failure of the head gasket is caused by the constant exposure to heat.

When it comes to older cars, blown head gaskets can only be replaced if other parts are damaged as well.

Even if it’s worth replacing, there’s a good probability that other elements of the engine will be worse off as a result.

2. Make And Model Of Your Car

On the replacement cost of a car, make and model are the most important factors.

Repairing a sports car or a high-performance vehicle may be more expensive than fixing a less expensive vehicle. Modern autos with complex engines are the same.

The cost of a new engine depends on the time and skill required to disassemble the old one. The engine block and cylinder head both influence the material of the head gasket.

3. The Severity Of The Damage

A blown head gasket won’t impact other elements of the engine as much if you get it checked out right away.

However, it is rare for a head gasket to break on its own accord. It starts to leak, and if it’s not caught, it grows worse. Once and for all, your gasket popped.

A blown head gasket damages the cylinder, piston, thermostat, cooling system, exhaust, and many other parts of the engine, causing it to malfunction.

Regardless matter how old the car is, the damage’s extent is a crucial factor in its repair price.

4. Type Of Engine

As I’ve said before, the cost of repairing a blown head gasket is highly dependent on the scope of the labor involved.

Getting to the head gasket necessitates the engine being dismantled in order to access it. This includes checking the cylinder and piston for damage.

If the engine is a V6 or a V8, the price goes up much more.

V6 and V8 engines have two cylinder heads, which necessitates a longer repair period and thus a higher price. Repairing a Subaru Boxer’s engine, for example, is a challenging task because of the engine’s intricate design.

5. Type Of Gasket

Various materials are used to make the head gaskets, including rubber, cork and copper.

Depending on its intended use, they can withstand heat in a variety of ways. What type of gasket does your mechanic use? It depends on your cylinder’s strength and how much pressure it can handle.

Unless you choose more expensive varieties like copper, the gasket type has no bearing on repair costs.

How Does The Auto Repair Shop Fix The Rates?

It doesn’t matter how many times I explain hourly rates, the mechanic doesn’t understand what I’m saying. In addition to his/her salary, the hourly rate includes the shop’s physical costs.

There’s also the cost of the high-tech diagnostic tools and other equipment.

As a result of the expenses, you’ll be required to pay a percentage of the aforementioned.

Auto repair companies employ a computer program to determine how long it will take to finish a certain task. When multiplied by the hourly rate, you get the ultimate repair price.

As a result of this approach, the repair shop is able to accurately bill clients. You can also rest easy knowing that the mechanic won’t have to spend a long time on your repair.

With this system in place, a technician’s hourly rate is increased if the task is completed ahead of schedule. If this is the case, they will be paid at a rate that is significantly lower than their hourly wage.

Diagnosis Pricing

Not all repairs are covered by the flat-rate method. Isn’t useful for complex topics that require a lot of investigation to solve.

The repair company will provide you with an estimate of the time it will take to complete each process. However, in principle, your repair should be completed by this time.

Consider electrical troubles, for example. Diagnosing the problem can take a long time, but fixing it only takes a few minutes.

When it comes to this situation, the diagnosis is inevitable. In other words, you’re paying for the services of someone who has the knowledge and experience to identify the issue.

When it comes to a head gasket replacement, you already know what’s wrong. However, the time it takes to disassemble and reassemble the engine is what takes the time.

Thus, the flat-rate system and the mechanic’s hourly rate, or should I say the hourly rate of the shop in question, are applicable.

Menu Pricing

There is no doubt that you’ve come across or perhaps used menu pricing at some point in your life. This includes things like oil maintenance and brake jobs.

Parts and labor are included in the agreed-upon price, but anything additional is a separate charge.

For example, if the repair shop delivers you 5 quarts of oil as part of the stated oil change, but your car needs more, you will be charged for the additional oil.

Even if your filter requires additional maintenance, you can rest assured that you will be charged for it.

Prior to signing off on any work, make sure you have a list of tasks and a documented estimate in your possession.

Factors Influencing Labor Rates

Isn’t your jaw dropping at the mechanic’s hourly rate or the cost of a head gasket replacement?

In spite of what it may feel like, you are not being robbed in any way.

In order to make things clear, below is a list of criteria that influence the price:

Dealership or independent repair shop

The facility’s operating costs.

The type of vehicle they work on – whether it’s an exotic or a typical model.

Costs of labor

Costs of doing business

The technician’s level of competence

How Long Does A New Head Gasket Last?

An engine in good functioning order might extend the life of your new head gasket by as much as ten years. If your engine overheats, it will likely burst into flames again within a short period of time.

Even if the thermostat is working properly, the engine can overheat due to low coolant levels or even problems with the combustion process itself.

Can I Repair A Blown Head Gasket Without Replacing It?

There is no need to bring in a mechanic if the leak is minimal and has been discovered in the early stages of development. A sealant can be purchased and used to complete the task.

A replacement may be necessary if the damage is too extensive. Even if you use a sealant, the job is only temporary and you’ll have to pay for a new one.

How Long Does It Take To Fix A Blown Head Gasket?

To replace your head gasket, allow two days to two weeks of time. It’s a pricey fix that necessitates a high level of expertise to replace.

Several factors, including but not limited to:

As a result of the engine damage

An on-site technician’s availability

a description of the engine

The engine’s accessibility is crucial.


The replacement of a head gasket is a complex repair that necessitates much effort, expertise, and financial resources.

Depending on the location, damage to the components, the type of engine, and the make and model of the automobile, your repair shop can charge you anywhere from $1500 to $2000.

Even though the cost of repair is expensive, it is not solely determined by the mechanic’s hourly rate.

Overhead expenditures, diagnostic time, and technician expertise all play a role in the repair prices.
