odonian Posted August 13, 2018 Share Posted August 13, 2018 Hello, I have isolated a coolant leak to the small hose coming off the crossover pipe just to the side of the temp gauge, on the passenger side of the car, the hose seems to pass directly under the idle air control valve. I can not find a diagram or picture showing where this hose leads, so I am having a hard time determining what hose I need to purchase for a replacement. I have a 2.2L EJ22 legacy. Any help is greatly appreciated. Quote Link to comment Share on other sites More sharing options...

ocei77 Posted August 13, 2018 Share Posted August 13, 2018 (edited) The hose goes from the throttle body to the crossover pipe. It acts as a return line that goes from the bypass pipe to the TB. Its designed to keep the throttle body from icing up. Some people in hot climates just bypass or plug them as icing is not a concern for them. It will show up in service procedure for the TB. Use an online dealer part cat. to look up the actual part no. if you need it. The dealer should be able to get it w/o a number. Its on all the EJ22 and EJ25's at least up to 06. O.

O. so that would mean the hose I need is the part 13 in the upper right corner of this diagram http://opposedforces.com/parts/legacy/us_b11/type_39/intake_and_supply_system_turbocharger/intake_manifold/illustration_4/ ? Sorry to be so needy, I only know as much about cars as is required to fix things that have broken previously. Quote Link to comment Share on other sites More sharing options...
