Just tried cleaning out my icv on my wrx blob as the idle is fluctuating between 400- 700rpm and as soon as i undid the screws on top coolant squirted out of the top, is this supposed to happen? do you have to drain the coolant before you clean it? cheers

 

get a new gasket before you remove anything

 

will this one fit a 2005 blob ? http://www.ebay.co.uk/itm/GENUINE-Su...item3f2ba1b0b4
it says it wont but it looks the same shape

 

that's import car parts very good to deal with email him and he will let you know for sure
