(I'm not quite sure where a How To goes since the sub-forum is locked, so I figured I'd put it here. If anything is incorrect here let me know and I'll change it. This is based on talking to the service people at my dealer and my experience today)

This post is for SG Foresters, but likely will apply to other models as well. If anyone can confirm it would be great. The kit is for all Subaru's but the directions/pictures are specific to my SG

My car has developed somewhat of a musty smell coming from my air conditioning vents over the last few months. My brother had told me that a dealer down in LA had done some kind of cleaning for him at a cost of around $90.

Well today at the dealer I saw the A/C cleaning stuff at the parts department and figured I'd pick some up. It is super-easy to do.

Our local club pricing on the cleaning kit was $14.36, and the list price shows as $17.95

The part number for the kit is SOA868V9315. The kit comes with two aerosol cans and a piece of tubing.


One can is a kind of foaming cleanser for the evaporator, the other is an aerosol cleaner for the intake and venting system.

The instructions are pretty simple.

-Firstly it's recommended that you remove your cabin air filter. I suppose you could do it without, but it would kinda nasty. The can's don't say anything about removing it, but I sure would. Also you want to put all of the windows down.

To remove the cabin air filter (if you have one) you remove the glove box, pop off the filter cover, and pull the filter out. If you need to replace the filter, this project kills two birds with one stone. For more detailed instructions see Peatys thread over on ScoobyMods
http://www.scoobymods.com/cabin_air_filter_kit-t2109.html

Make sure after removing the filter you put the filter cover back on! If you don't air will not be pulled through the fresh air intake and the second step will not work.

-There is no need to put the car on any kind of lift like the can says since we can access the evaporator drain tube from under the hood and you can get a drain pan under the car without a problem.

-The drain tube is located on the passenger side of the firewall. This is just behind the turbo on XT models. It is held against the firewall by a little clip, but slides out without a problem. Remove the hose from the clip so you can get to the end and plug the end with the wedge shaped end of the hose that came with the kit.


-Now hook the tube up to the larger canister and spray the whole contents into the tube. This will take a couple of minutes


-Once the can is empty, make sure you have a drain pan of some sort under the drain tube location. Remove the wedge plug and let everything drain for about ten minutes.

Now for the second part, the "A/C Intake Refresher."

-First you need to disable the A/C compressor. To do this just unplug the one wire that is on the top of the compressor (This controls the compressors clutch). The compressor is located just to the right of the alternator if you are standing at the front of the car looking into the engine bay.


-Next you want to start the engine. Make sure that the air recirculation setting is OFF. Turn on the A/C mode, set the A/C vent directional control to the "body" setting, (this means the vents on the dash only) the temperature setting as cold as it will go, and set the fan speed to high.

-Now spray 1/2 of the contents of the can into the fresh air intake which is located just below the wipers on the passenger side of the car.


-Next switch the directional control to the "Foot" position and spray 1/2 of the remaining contents of the can into the fresh air intake.

-Finally switch the directional control to the "Defrost" position and spray the rest of the can into the fresh air intake.

-Once this is all done, the directions say to continue ventilating the vehicle and running the fan with the windows down to get rid of the vapors. I let the fan run for about 20 minutes after I was done.

Now you can put the cabin air filter back in or install the new one. Put the glove box back in, reconnect the A/C Compressor clutch wire, clip the evaporator drain tube back onto the firewall, and you're good to go.

The vapor smell stayed around for a few hours in my car but has pretty much disappeared now. The musty smell disappeared immediately, and hopefully that remains the case for a long while.

Sweet, I take it the musty smell has gone away? Going to have to do this once my engine transplant is done.

Yup. The real test will be over the next few days when the cleaner smell is totally gone. There is still a tiny hint of it lingering.

The catch pan that I used had been used for oil in the past so I'm not sure if that has anything to do with it, but the stuff that was in the catch pan was purple... I know the color of the foam was white going in.

How it became purple I don't know, but it was completely nasty.

Thanks for the write-up. It is something I am going to do. How is the smell? Has it come back?

I'm very pleased with the results. There is now no lingering chemical smell at all, even when I first turn the car on and stick my nose in front of the vents. (My neighbors must think I'm insane) The air now has no real smell at all, good or bad. The musty smell is totally gone:woohoo:


Well worth the money and time IMO.

Thanks a million for this write up! The cans that came with the kit does not have such detailed instructions!

The liquid that dripped out sure looks dirty! And my car is only 2 years old!

Now the odours are gone!!!!

I'd love to run this stuff through my system, but I can't seem to find it anywhere! Both local dealerships have told me I can't get it, and three orders I've placed online have been cancelled because they don't stock the kit.

At this point I feel like I'm trying to buy contraband!

Anyone know a guy that knows a guy?

That blows. My dealer has 17 cans in stock right now and the other dealers in town have about the same. Keep calling around and you'll find some.

Just out of curiosity, has anyone in the SF world tried this? I've got a 2000 L that could use it. Not terrible mind you but definitely could use this.

I can't imagine that it's much if at all different.

One thing to remember on SF is that the Air-filter, if equipped, is not behind the glove box, it is underneath, and within easy reach, no need to take off the glove box.


Just take off a few clips and pull it out. It comes out in 2 pieces.
