Lawsonmh15 Posted November 11, 2005 Share Posted November 11, 2005 Recently Cleaned the IACV and had to do ALOT of fiddling to get it back to normal. AFTER that saga, I went through my FSM pdf's and found that there is an actual service procedure for the 2.5 that does NOT require removal. Oh well, lucky YOU. EDIT: I should also mention that the full service procedure for the 2.2's are included as well. Click HERE I would use Sea Foam as the agent. PS. It's on the right side, midway down on the third page. Enjoy. Quote Link to comment Share on other sites More sharing options...
nickb21 Posted November 11, 2005 Share Posted November 11, 2005 Awesome timing, I was hoping to remove and clean my IAC this weekend. I'll definitely try this first! Quote Link to comment Share on other sites More sharing options...
Lawsonmh15 Posted November 11, 2005 Author Share Posted November 11, 2005 Awesome timing, I was hoping to remove and clean my IAC this weekend. I'll definitely try this first! I just used this method. Kinda tricky, but I used my left hand to open the throttle, and my right to pull the hose up and situate it on the intake hose. Switched hands on the throttle, and poured the Sea Foam in straight out of the bottle. Tried a small bowl first... Not happening. Easy fixes are the best. Now I have to wait for a new IACV gasket to come in at John Elway then re-re-re-do the IACV. Should be in this afternoon. I can't believe that the IACV bolts only take 4-5 ft/lbs of torque :-\.

edrach Posted November 11, 2005 Share Posted November 11, 2005 I should also mention that the full service procedure for the 2.2's are included as well. Click HERE Procedure for the 2.2's only seems to be removal/replacement. Is there an actual cleaning procedure? Looks like a fine CD; is that available from Subaru? I'm looking for one for my '91 Legacy and '97 Impreza. Quote Link to comment Share on other sites More sharing options...

Looks like a fine CD; is that available from Subaru? I'm looking for one for my '91 Legacy and '97 Impreza. They did the same thing as the 2.5 procedure on my 2.2 worked like a champ, that was about 15k miles ago. Quote Link to comment Share on other sites More sharing options...
avk Posted November 11, 2005 Share Posted November 11, 2005 The procedure for original style, solenoid (not stepping motor) IAC valves is simply to disconnect the bypass hose from intake duct and pour the cleaner in it with engine running.
