2006 wagon: Evaporator core replacement

Recommended Posts

The local Subie shop quoted me over $1000 to replace my condenser coil, so I bought a tester and confirmed that the leak is in the evaporator. Now that I've confirmed they're not only pirates, but that they're incompetent pirates, I figure I may as well make good use of my unemployed status and swap it out myself.


Given the OEM part is almost $500 and I can do an aftermarket for 1/10 that, I'll be taking the cheap route.


Any particular gotchas to watch out for? Specific bushings or o-rings to have on hand before starting?


Also, I've never disassembled my dash before, and I can't find an '06 service guide. Would it be closer to the '05 or the '07?

For anyone coming this way later on, the hardest part was that the evaporator coil is held on by two nuts and a bolt. The upper nut is deeeeeeep in a well, obstructed by the main structural bar across the dashboard. The stud protrudes too far to get a socket over it, and there isn't enough room to get a deep socket in there. Nightmare!


I managed to do it only by stacking up a socket, a hex-bit adapter (fitted loosely into the end of a socket to provide room for the stud), and a right-angle bit-driver.


Also, a steady stream of cursing for about 15 minutes seemed to help.

Also, be very generous with the refrigeration oil when you reassemble the O-ring fittings. My reassembly left a leak at one of the o-rings. I eventually took it to an AC specialist shop, and the guy there told me that it's pretty common to have o-rings roll over a bit if they aren't quite lubed enough.
