What should head torque be on 2009 EJ25?
Your head torque values are for an earlier engine – NOT a 2009 N/A EJ25 Impreza. You should have: Use a new cylinder head gasket. (1) Clean the bolt threads and the bolt holes in the cylinder block. (2) Apply a sufficient coat of engine oil to the washer and bolt thread. (3) Tighten all bolts to 40 N·m (4.1 kgf-m, 29.5 ft-lb) in alphabetical order.
How do you change the head gasket on an EJ25?
Use a new cylinder head gasket. (1) Clean the bolt threads and the bolt holes in the cylinder block. (2) Apply a sufficient coat of engine oil to the washer and bolt thread. (3) Tighten all bolts to 40 N·m (4.1 kgf-m, 29.5 ft-lb) in alphabetical order. (4) Retighten all bolts to 95 N·m (9.7 kgf-m, 70.1 ft-lb) in alphabetical order.
Where are the bolts on an EJ25 head?
Bolts (a) and (b) are the two center ones the outside four should be an “X” pattern. do (a), (b) and then “X” in each step except step 11. The first tighten/loosen is to seat the head and gasket as there supposedly a tendency for the head to slip around. These head are located with dowels so your guess is as good as mine.
What kind of head bolts does a Subaru 2.5L use?
The Subaru 2.5L engine is made from aluminum alloy. In order for the heads to properly seal and to prevent warping, a special sequence must be followed when installing the head bolts. Not only is the tightening method critical, so is the order. You will need both inch and foot pound torque wrenches as well as a torque angle gauge.

Do you need to replace head bolts on a Subaru Outback?
This comes up from time to time. Right on, the Subaru manual does not show that the head bolts need to be replaced. The consensus seems to be reuse once or twice is fine; after that maybe consider replacement. I would follow the latest Subaru factory manual instructions for installing the head gaskets.
What are the torque specs for a Subaru Outback?
Turbo tightening sequence is almost exactly the same. Just change 31 ft/lbs to 36 ft/lbs before the angle tightening sequence. The torque specs for any engine depend on the head, gasket and bolt tolerances combined with engine compression and valving. I would go with the Turbo specs and new bolts unless the bolts you have are good for another go.
