Subaru head gasket problems explained
The head gasket issue for Subaru has affected lots of their models over the years. The ones it affected most are the Legacy, Impreza, and Outback from 1999 to 2004.
They all use the 2.5 SOHC engine so that is the main reason why these models are affected. Their engine causes loss of coolant, overheating, and black colored coolant.
Lots of engines Subaru engine might experience this gasket failure but there are some that are widely known to encounter it more often.
They are Subaru Impreza (1999 to 2011), Legacy (2000-2009), Outback (2000-2011), Baja (2003-2005), and Forester (1999-2010).In 2011, the Impreza was the only model encountering the head gasket problems.
It was redesigned the following year and its entire leaking problem was fixed.
The first designed Subaru 2.5 engine gives symptoms of a damaged head gasket. There is usually an oil residue and an exhaust fuel in the bottle or it smells like sulfur.
Once you notice this, the temperature gauge will start reading higher which will cause overheating.
The second generations of Subaru with this problem are the Subaru 2.3 and 2.5 liters. The major sign will be a coolant leak or external oil leak at the left head gasket.
These symptoms are most common to these second-generation engine.
How to tell if Subaru head gasket is blown
If you are using an older Subaru model, the symptom that your head gasket is blown will be overheating.
When most of the materials of the head gasket are damaged, you will be able to see certain signs that the head gasket is blown.
The obvious one is that you see a white exhaust from the tailpipe. This white smoke is due to the lack of heat in the combustion chamber.
This means that the fuel is not burning at its correct proportion. However, the white smoke sign can be because of a damaged or obstructed fuel filter or if the diesel is contaminated.
In their petrol cars, it can be because of a burning coolant while black smoke can be a symptom of oil-burning inside or a failed engine.
Some of the other symptoms to look out for in older models are:
- Engine overheating
- Exhaust bubbles
- Vapor in the coolant reservoir
For newer models, the symptoms include:
- A very high temperature while it is working
- Overheating when traveling a long distance
- Low coolant
- The block and head near the engine will start dripping oil.
How do I stop my Subaru head gasket from failing
When it comes to Subaru, you can find various ways to decrease the probability of the head gasket failing.
When you do this, you reduce the chance of damages and increase the lifespan of your Subaru car.
Change of Oil
The first thing you need to do is always change your engine oil regularly. The compressed air-fuel in your car meets a spark from the spark plug in the combustion chamber. This leads to an explosion and then power.
During this process, all the fuel that enters the chamber is not burnt. The leftover fuel will mix with the oil and the solvent fuel will erode the gasket.
If the oil gets to its proper temperature the fuel will evaporate into the manifold where it mixes with the combustion chamber air.
When you change the engine oil regularly, the risk of the fuel leaking in the wrong places will reduce.
Another way to prevent this problem is to watch the Subaru battery very closely. The battery should last about 3 to 5 years before it starts leaking acid.
The battery powers the car accessories when the vehicle is not working and also starts the vehicle.
When the alternator cannot endure the load, it drains power from the battery. Since it is close to the radiator and also the electrical system, it can influence the cooling system voltage which can make the coolant corrosive.
When the battery is not taken care of properly can lead to a corrosive cooling system. This corrosion will eat the metal, seals, and head gasket.
If you are using a newer engine of Subaru, it usually affects the left side head gasket. A leaking battery can cause damage to the head gasket. Therefore, you need to keep a proper eye on your battery.
Changing the coolant
When the coolant in the Subaru takes too long, it can become corrosive and damage the seals and gaskets.
Therefore, you need to change it regularly. If you are using a second-generation engine, then you can make use of antifreeze.
Check your Subaru regularly
Make sure you regularly inspect your vehicle by taking it to a Subaru specialist. When you do that, you are making certain it gets the best care possible. With this you can avoid head gasket problems.
