alvaro quinonez Posted February 9, 2011 Share Posted February 9, 2011 I found this part screwed underneath the intake manifold it is supposed to have 2 small plastic peices that broke(where my fingers are) that fit into 2 different hoses. the first hose attaches to the top of the throttle base and the 2nd hose is hidden beneath the intake manifold and attached to a long horizontal metal rod that curves deep into the engine. My main question is WHAT IS THIS PART? WHAT DOES IT DO? my car is a 1999 subaru legacy outback. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 10, 2011 Share Posted February 10, 2011 That is the evaporative emissions system canister purge control valve. It opens at specific intervals and driving conditions to allow engine vacuum to pull fuel vapor out of the charcoal canister. The canister stores fuel vapors that build in the gas tank to prevent them form escaping into the atmosphere. Just grab one from a junkyard.

Fairtax4me Posted February 10, 2011 Share Posted February 10, 2011 Just so you know you can drive around without that for a while if you need to. Just plug the hoses with small bolts until you get a replacement. You'll get a Check engine light if the valve is unplugged, but it will still run fine as long as the hoses are plugged closed.

alvaro quinonez Posted February 11, 2011 Author Share Posted February 11, 2011 awsome tip, I was wondering how I was previously driving without it. I found the part thanks to you, THANK YOU. I found this part named as a "duty solenoid valve" at the subaru dealership for $134. I should have went to the junk yard like you advised. I discovered the broken solenoid in the process of changing my "ect sensor" beacause I have overheating. I have done everything to fix the overheating except check for blockage in the heater hoses. Are the hoses pictured here? Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted February 11, 2011 Share Posted February 11, 2011 heater core? those are the A/C system lines you want to look on page 3-6 but it still does not show where the heater core is if that's where you are trying to get to. Quote Link to comment Share on other sites More sharing options...
alvaro quinonez Posted February 11, 2011 Author Share Posted February 11, 2011 (edited) thank you "1-3-2-4" do you know which number the hoses are on the page you gave me? Yes they lead to the heater core and they are discussed on page 3-18 under "heating systems" .

Fuzpile Posted February 11, 2011 Share Posted February 11, 2011 In engines, rapid heating of another core involves a shunt, a bypass Now if we consider You've done "everything" and need to find these hoses .. it may be possible the shunt exists yet the port/valve to expelling the heat to the heater core is blocked. i cannot be more specific to Subies yet had experience in other vehicles where this had occurred. i just want others to understand where U were going.

Fairtax4me Posted February 11, 2011 Share Posted February 11, 2011 Don't think his year has a valve to the heater core. The later ones might I don't know. The heater core hoses do serve as the bypass hoses, which bring hot coolant from the engine back around to the thermostat which is on the inlet side of the water pump. This flow of hot coolant keeps the thermostat from closing when driving in cold weather. Overheating Subaru 2.5 DOHC engine. 3 main reasons: Head Gasket Thermostat Air pocket in the cooling system If you have bubbles pushing out into the overflow tank when the engine is running, it's probably the head gasket.

alvaro quinonez Posted February 12, 2011 Author Share Posted February 12, 2011 dear fairtax4me, once i see steam, is it ok to remove the cap from my coolant overflow tank to check for bubbling? Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted February 12, 2011 Share Posted February 12, 2011 dear fairtax4me, once i see steam, is it ok to remove the cap from my coolant overflow tank to check for bubbling? yes, the over flow only. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 12, 2011 Share Posted February 12, 2011 ^ ^ ^ What he said. ONLY the black/yellow plastic overflow cap. DO NOT open the radiator cap unless you're prepared to get sprayed with burning hot coolant. Quote Link to comment Share on other sites More sharing options...
