Subaru Head Gasket: Why the Head Hasket is Important for Subaru

A vehicle has different moving parts, such as the cylinder head gasket, which consists of a thin piece of metal that includes some drilled holes.

This part is incorporated in the assembly process and installed between the cylinder heads and the block. The main task is to absorb the kinetic energy in each component that is close to the engine area.

Additionally, these parts can keep the coolant in each of the right places, and the same task is performed with the oil lines.

So when the cylinder head gasket breaks, they need to be replaced immediately. If this procedure is not carried out, certain disadvantages and additional problems may occur.

Multi-layer steel part: One of the most suitable options is the multilayer steel gasket, the solid copper part of the composite part.

The difference between these head gaskets is the robustness and strength they can provide. The MLS cylinder head gasket is usually the most commonly used today.

However, it is the most expensive option overall.

Copper head gasket: Another option is the copper head gasket as an alternative to the one mentioned above.

This is a more expensive part than the multilayer steel head gasket.

However, this cylinder head gasket’s strength, service life, and proportion are also usually excellent for high-performance vehicles.

How to Replace Subaru Head Gasket

Cylinder head gaskets on a Subaru can be replaced while the engine is still in the car. The procedure is a difficult task that experienced mechanics should only attempt.

To get started, you’ll need to gather several different types of automotive service tools, safety glasses, and gloves to protect yourself from caustic chemicals and gasoline.

The first steps

If you have a fuel problem, it’s annoying. Use a paperclip to reset the ECU with a key and run the car until it stops. Now turn off the ignition and disconnect the negative battery terminal.

If your vehicle is pre-2002 and has the factory vehicle theft system, follow the instructions in the owner’s manual to disable it, or your radio will not work when you reconnect the battery.

To drain the engine cooling system, remove the engine cover on 1996-2003 models, loosen the overflow tank cap, and open the petcock on 2004 – 2008 models.

Next, use a funnel to remove approximately two quarts of coolant into a clean container for reuse or recycling.

Remove the spark plugs

Disconnect the battery, remove the spark plugs and the timing belt covers and first and second catalytic converters (in some models, first and second catalytic converters leave through the front), and remove the belt camshaft sprockets.

Remove the exhaust manifolds and any extended bracketry blocking access to the sides of the engine.

You’ll need to remove the engine cover. First, loosen the cylinder head bolts in the reverse order you used to tighten them (top to bottom, then an “X” pattern for the end bolts).

The heads should come off with little resistance.

The last steps

Removing the old gasket may require some effort. To make sure the studs are clean, wipe them with acetone or similar products.

The threads should be clean and free of coating. Install the new gasket onto the head studs carefully.

Lubricate them with engine oil before you tighten to the specified torque. Always follow the sequence of tightening bolts as outlined in your car’s owner’s manual.

An improper sequence may cause the head to warp.

Top 07 FAQs about Subaru Head Gasket Replacement

01. What is the average cost for head gasket replacement?

When it comes to head gasket replacement, there are a few basics to consider. In most cases, it is possible to purchase the head gasket for less than $200.

The central part of the cost is always in labor. The budget for this factor usually increases with the difficulty of the task.

Also, in some geographic regions, the cost of labor is often cheaper or more expensive than elsewhere. So, the average cost for a Subaru head gasket replacement is $1500.

02. What are the consequences of a broken head gasket?

When a head gasket breaks, the temperature of the vehicle could increase too much.

This is usually a direct consequence of the broken head gasket or an indirect consequence of what happens because of this situation. With a broken head gasket, the coolant and engine oil will start to leak.

So this means that the vehicle will have less of each of these fluids. Both the engine oil and coolant can lower the temperature of the engine.

So the temperature begins to rise, damaging the rest of the metal parts of the engine.

03 What happens if the coolant leaks from the vehicle?

The coolant is one of the most important liquids in the vehicle since it reduces the temperature generated by the engine operation.

High temperatures can deform the metal parts that make up the engine.

So a high temperature of the vehicle could produce all kinds of unexpected damages with enough time. That is why it is essential to prevent the vehicle’s coolant from starting to leak.

04. What happens if the vehicle oil leaks?

Engine oil is another of the essential fluids in the vehicle, and it is not only responsible for lowering the engine’s temperature.

Engine oil is essential to provide the necessary lubrication. This lubrication ensures that the different moving parts of the engine do not produce friction when operating.

When the vehicle’s engine oil levels drop too low, the friction could increase considerably. Thus the rate of engine wear begins to increase at a worrying rate.

05. Is it easy to replace the cylinder head gasket?

To be able to replace a cylinder head gasket requires some basic knowledge of the engine. Of course, it is possible to follow a guide with all the necessary steps to perform this task.

However, a wide variety of moving or fixed parts must be taken into account in this procedure.

It is possible to start the task with some basic knowledge as long as the person has all the elements. These elements are not only related to essential tools or vehicle-specific tools.

The elements that must be taken into account are also related to the safety of the person himself.

06. Does high temperature damage the cylinder head gasket?

For different reasons, the vehicle could get too hot inside the engine—one of the parts that can be damaged due to high temperatures in the cylinder head gasket.

When the vehicle produces too high a temperature on certain occasions, it is necessary to reduce this factor.

In addition, it is also recommended to check the condition of each of the parts inside the engine, including the head gasket.

As mentioned above, a broken head gasket allows some of the coolant and engine oil to leak out.

07. Can water be used instead of coolant with a broken head gasket?

When coolant is lost due to a broken head gasket, it is possible to use water. However, it must be taken into consideration that water is much less efficient than coolant.

In addition, water tends to evaporate and be lost much faster than coolant.


All those people who wish to replace the best Subaru head gasket by themselves need safety items and tools.

It is recommended to check Subaru head gasket replacement cost and have an expert mechanic to avoid different dangers when you are a beginner without much knowledge in it.

In this way, you can obtain a much safer and more reliable result.
