bcurley Posted January 20, 2010 Share Posted January 20, 2010 Hi, I have a 1994 2.2L Non-Turbo AT FWD Legacy with 180k miles. I removed the IACV to clean and test it. I see the valve open and close on the engine side. On the hose tab, I see a tab sitting about a quarter into the opening. Was wondering if something should be moving on the hose side as well. Didn't think it should but thought I should ask before reinstalling it. Why did I remove it: Car would not start and after doing some tests just started running again but had a rough idle and threw a Code 24. Tried using seafoam through the hose to the IACV but that didn't help (seemed to make it worse) so thought I would pull and test it. Thanks, Bob Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted January 20, 2010 Share Posted January 20, 2010 That tab on the hose side is tied into the coolant lines that go to it. It's a bimetallic strip that opens/closes as coolant temp warms up. It's supposed to help with the cold start warm up. Quote Link to comment Share on other sites More sharing options...

lewisd Posted January 21, 2010 Share Posted January 21, 2010 just checking but did you get a new gasket for reinstalling? I did mine recently and the old one was out of shape and impossible to fit back into the grooves. Quote Link to comment Share on other sites More sharing options...
bcurley Posted January 21, 2010 Author Share Posted January 21, 2010 I did. Mine doesn't have groves to go into though (the engine surface and IACV surface are flat). Quote Link to comment Share on other sites More sharing options...
