Impreza 2.5 RS Sedan AWD F4-2.5L SOHC (2002)
13)
Remove two (2) 4 mm Alan screws from the same location. These are found after the lines are removed. Do not remove the aluminum block at this
time. It must come out from the inside.
14)
From under the dash you can now remove the expansion valve block (gold in color), followed by the aluminum block previously mentioned. Cover
openings to prevent contamination and catch any oil that may leak out to prevent customer complaints.
15)
You can now slide the evaporator out to the right with the Thermosensor probe attached. Work it out slowly because the wiring harness attached
above the evaporator on the top of the dash will be in the way.
16)
Remove the old surface mounted Thermosensor and discard it. Replace it with the new style internal Thermosensor P/N 72166FE010 and Plastic
Holder P/N 73552FE000 at the new location as shown in the picture in this bulletin. The metal Thermosensor and clip goes in the eighth row from
the right and 30 mm up from the bottom fin. Assemble the Thermosensor and the plastic holder first, then push them both into position. The plastic
tab goes to the right of the metal Thermosensor in the seventh row.
17)
Replace all six (6) of the 0-rings as listed at the beginning of this bulletin on the high and low pressure lines and the expansion valve.
18)
After the evaporator is reinstalled and the lines are secured, test the integrity of the seals by pulling and holding a vacuum on the system. This is
done before the final assembly.
19)
The white cover must be sealed from the lower corner where the Thermosensor wire goes through to the top side as far as you can reach. Failure to
do this will cause water to leak out on the carpets.
20)
Assembly is in the reverse order of disassembly.
