Summary
Subaru
of America, Inc. (Subaru) is recalling certain 2013 model year BRZ and XV Crosstrek and 2012-2014 model year Impreza vehicles to replace the engine valve springs which may fracture. A total of 139,324 U.S. vehicles will be affected by this recall.
First and foremost, Technicians need to TAKE THEIR TIME when performing these intricate
repair procedures. Rushing through the steps, especially when reinstalling the retainer /
keeper assemblies MUST be avoided.
•
Considerable time and resources have been spent by SBR to develop and refine these tools to
perform these procedures. Used as intended, they will fulfill the task as designed.
•
When Technicians TAKE THEIR TIME, a “feel” will be developed for when the special tools
and related engine components are in the proper positions to perform their intended task. If
the tool and / or an engine component is out of position, when tightening the push bolt, the
tool will most likely be damaged, or WORSE.
•
It cannot be stressed enough, HAND TOOLS ONLY. Air or electric tools must NEVER
be used to perform any of these procedures. The “feel” referenced above will never be
developed when using any sort of power tool.
•
Whenever tightening the push bolt, if anything more than minimal resistance is ever felt,
STOP IMMEDIATELY and investigate the reason why before damaging the tool being
used and / or an engine component.
•
There is no need to use anything bigger than 1/4” drive hand tools on any step of this
procedure where the use of a special valve spring remover or installer is required.
•
ALWAYS confirm the proper remover / installer tool is being used for the specific task being
performed. The Intake and exhaust tools are not interchangeable.

The photos below show examples of damaged tools caused by improper use or the use of air or
electrically-operated power tools.
Stripped Threads
The most common reports received involve damage to the valve spring re-installation tools. A close
inspection of the tools to see how they work is highly recommended. Although they may appear
complex with a lot of small moving parts, when used as designed, they will make the process easy to
perform every time. The photos below show close-ups of damaged installer components, all resulting
from excessive force and not stopping when additional resistance is felt when turning the push bolt.

REMINDER: When installing the spark plug adapters, hand-tightening only will seal the adapters
sufficiently. NO tightening tools should be used.

Look closely at Photo “A” above. The “OK” portion of the tool shows the keeper ring around the
keeper guide in the proper “flush” position. On the “NG” portion, the keeper ring is shown receding
below flush as a result of being caught by the valve stem and bending the ears on it. A photo of this
component removed from the tool is shown below as “B”.
The root cause of this damage is not centering the spring
and retainers to the head, valve stem and the installer tool
before compressing the spring pair.
In this photo, one ear of the keeper ring is bent and the other has
been snapped off.
B
Review the photos and steps below.
In photo 1 below, the valve springs are not
positioned properly to be ready for retainer
/ keeper installation. The valve stems must
be centered (or close to it) before putting
the loaded installer in position.

NG
In photo 2, the retainers and keepers have been loaded onto the installer and the installer onto the
springs. Notice how the spring is protruding from the right edge of the installer and also not centered
on the underside of the tool or the spring seat cast into the cylinder head. If the Technician were to
proceed with tightening the push bolt at this point, the installer would most likely be damaged.
•
When using either “C” spring installer tool – once the keepers and retainers are loaded and the
tool is in place on top of the springs, the push bolt should be turned until it just makes contact in
the bottom of the tool’s receiving bore.
•
Turn the push bolt one (1) full turn by hand to apply a very light amount of pressure on the
spring pair and retainers.
•
Rotate or move the valve spring(s) by hand or with a pocket screw driver as needed to center them on
the head and the underside of the installer tool. Do this for both springs. If the springs are off-center,
the Technician should see, feel and / or hear when they “click” into their proper positions. When this
occurs, the spring’s tension will also loosen slightly and, they will turn easier by hand.

•
Once both springs are in their proper positions, continue turning the push bolt by hand until you see
the upper portion of the installer’s keeper rings begin to lift before snapping the keepers down into
place onto both valve stems. You may also hear the double “click” when this occurs.
•
IMPORTANT REMINDERS:
○ Whenever tightening the push bolt, if anything more than minimal resistance is ever felt, STOP
IMMEDIATELY and investigate the reason why before damaging the tool being used and / or an
engine component.
○ It is NOT necessary to bottom out the push bolt on the bridge frame.
CAUTION: If these procedures are not followed, damage to the tool WILL occur when the end of the
valve stem catches the bottom of the keeper ring and bends sensitive parts of the tool.
Parts Inquiries:
The Claims Team has received numerous inquiries regarding additional parts not included in the Parts Kit
or on the table provided on pg. 3.
Supplemental Parts:
The only additional parts currently being covered AS NECESSARY as a result of severe corrosion and
not listed or included in the Parts Kit are the exhaust pipe center connection spring bolts and nuts. In the
majority of the cases, these bolts and nuts should be serviceable and reused. Both exhaust pipe connection
springs must be reused and should not be claimed.
NOTES:
• Oil filter replacement is NOT covered under this Recall. There is no advantage to replacing the oil
filter. If the vehicle is due for an oil and filter change, that should be a separate line item on the RO.
Although the engine oil is covered, the oil filter is not.
•
A/C o-rings OTHER THAN those provided in the Parts Kit are NOT covered under this Recall.
To clarify:
○ For FA engines, Service Procedure requires removal of ONLY the discharge (high-side) A/C line
from the compressor. The o-ring for that line is supplied in the FA engine Parts Kit.
○ For FB engines, BOTH lines must be removed from the compressor therefore, both o-rings are
supplied in the FB engine Parts Kit.

(2) Reassembly of INTAKE Spring Installer Tool:
(a) Confirm all components are thoroughly cleaned before beginning reassembly.
(b) Reassemble the center pins, support rods and support springs as shown in the sequence below
into the “plate sub-assembly”.
CAUTION:
•
When reusing the 2 center pin retaining screws, check for dirt, oil or any debris on the
screw threads and clean as necessary before installation. Replace any screws with damaged
threads.
(c) Set the plate sub-assembly back in place on the tool body. Place the 2 new reinforcing plates
from the repair kit into their positions as shown below. Secure them to the installer tool body
using the 4 new screws included in the kit but do not fully tighten them until after confirming
both support rods are installed in their proper positions.
New Reinforcing Plates
VERY CRITICAL NOTES:
As a result of these repairs, tool strength is improved by installation
of a reinforcing plate to prevent tool deformation (INTAKE installer
only). Therefore, if proper procedures are not followed such as
reversing the installation direction of the keepers, downward force
on the intake valve(s) can overcome the air pressure pressurizing the
cylinder. This may cause the valve to open allowing air to leak which
can result in an increased risk of the intake valve dropping into the
cylinder. To avoid this, always pay close attention to the installation
direction of the keepers, along with the setting positions of the spring
retainer and the valve springs whenever performing this procedure.
New Reinforcing
Plate
Both the intake and exhaust (“C”) spring installation tools are commonly damaged by improper
alignment of either the tool to the spring and retainer or the spring and steel valve spring seat not
properly seated down onto the cylinder head / valve guide boss. Often, both are misaligned. Always
TAKE THE TIME to ensure these components are properly aligned before using either “C” spring
installation tool to compress the spring pair assembly.
