When did the head gasket fail on my Subaru?
The main problem years are 1996 through 2004. The most common engine to have head gasket failures is the naturally aspirated (non turbo) Subaru 2.5 L four cylinder engine, commonly known as the EJ25 motor. The single overhead camshaft (SOHC) variant experiences failures much more frequently than the dual overhead camshaft design (DOHC).
What kind of coating does Subaru use on head gaskets?
The coating also compensates for surface finishes as rough as 80 Ra, instead of the 30 Ra or less often required by OE MLS head gaskets.
What are the models that have head gasket problems?
The breakdown of the affected models are the Subaru Forester from 1999-2010, Impreza from 1999 to 2011, Outback from 2000-2011, Legacy from 2000-2009, and Baja from 2003-2005. The wide range of Subaru head gasket problems means that numerous models have engine issues.
What to do if you have a head gasket leak?
One of the telltale symptoms of a head gasket leak is an overheating engine. If your engine starts to overheat, pull over to let it cool down for a bit before you continue driving.

What kind of headgasket does a 2.5L Subaru use?
The first-generation 2.5L does not have variable cam timing and the second-generation has variable valve timing or VVT. We use a different torque procedure for these engines and the headgaskets are different also.
What kind of coating is on Subaru head gasket?
The inner core is a layer of flat stainless steel sandwiched between and riveted to 2 layers of .010 embossed stainless with a flouroelastomer Viton coating. The Viton rubber coating is one of Dupont’s high performance elastomers.

How long does it take to repair a forester head gasket?
Repairing your forester head gasket might take up to two days as the technicians will need time to test and recheck it. It has been reported that the cooling system and sensors fail just after the gasket repair. You should not expect any problem after fixing it but just be aware that there is tendency for that.
What kind of gasket does a Subaru Impreza have?
The biggest stain on the company is the Subaru head gasket problem. Many of their models have been dented with this gasket problem. Their first-generation model was Impreza (1999). This was followed by Forrester (1999), Legacy (2000), Outback (2000) and Baja (2003), respectively.
Is there a multi layer head gasket for Subaru?
Subaru has been using a multi layer for a couple of years now. The newest models haven’t been out long enough to see what the results are but hopefully for all, we see a reduction in the frequency of head gasket repairs. Just keep up on the maintenance and your Subaru should give you many trouble free miles.
Can a head gasket be replaced without removing engine?
No dice. So I upped the ante money-wise and bought Thermagasket. It did seem to improve things insofar as the CEL no longer appeared, and the engine ran better; but it still drank coolant and the bubbles in the reservoir were still present. And then a side-effect materialized a day after I used Thermagasket: water pump leak!
What causes a Subaru 2.5L engine to leak coolant?
Faulty chemistry and corrosion are a common problem on older 2.5L models, in which coolant tends to leak from the left–side cylinder. This problem has largely decreased since Subaru added ground straps, which protect the most vulnerable part of the head gasket.
Are there any problems with a Subaru 2.5L engine?
Subaru 2.5L engines have a mixed history of cooling, head gasket and oil leaks. There are specific ways to test a Subaru 2.5L engine for leaks, and not all testing methods provide reliable results.
What to do if your Subaru engine overheats?
Once coolant leaks into your car’s cylinders or into the combustion chamber itself, you will see telltale white exhaust smoke. If the radiator in a Subaru is repaired or replaced, it’s best to test the vehicle before taking onto the road to ensure that the engine won’t overheat again.

Is the Subaru headgasket the same as the second generation?
If you were to go to Subaru and order the headgasket(s) it would be the same as the ones you’re taking off. The second-generation SOHC engines use the same fiber gasket but have an updated head torque procedure and if done correctly you should not have future headgasket problems.
Can a headgasket be replaced without removing the engine?
The engine is a lot easier to work on if it’s on an engine stand but it can be done without removing the engine. First off, the head bolts will not come out if done this way. They must be left in the cylinder head and make sure not to mix up the center two bolts, they are different and will not fit the outer cylinder head bolt holes.
One of the telltale symptoms of a head gasket leak is an overheating engine. If your engine starts to overheat, pull over to let it cool down for a bit before you continue driving.
Is it bad to have a blown head gasket?
The leak wasn’t too bad, so damage is minimal. Driving with a blown head gasket is not advisable. The longer the issue persists, the worse it gets. Driving with leaky head gaskets will ultimately cause more engine damage and a higher repair bill in the long run.
Can you change head gaskets on a Subaru Outback LL Bean?
Today I decided to proceed with changing the head gaskets on my newly aquired 2003 Outback LL Bean H6 engine. I have the manual that someone here posted (thank you Very much).
