I just blew a hose and I can't find it on any parts illustrations and the dealer parts department doesn't know what the hell I am talking about so I just need a little help to see if anyone knows the name of this hose or a part#. I bought one before a long time ago and the guy at the time said it was called a pre-heater hose but that doesn't ring a bell for the new guys. The coolant hose sits right next to the blow-off valve on the top of the motor. Hope the picture is clear enough to see what I am talking about. Any help would be greatly appreciated!

 

the bpv recirc hose? hard to see


nm. reread and now have no idea. is it a vacuum hose or a coolant hose? also where does it plug into on the picture and where is it headed?

 

It is the BPV recirc hose.....Connects the BPV back to the intake.

 

21204AA711. I'm assuming your car is an 02/03 2.0 by the picture.

 

If it's the one connected to the throttle body I think it's feeding in to the IAC valve

If it's the fatty one underneath it's the BPV recirc

 

It has coolant so it is not the hose that recirculates from the BPV to the intake. The recirculating hose is attached on the right of the BPV and the bad hose is just to the left of the BPV that connects down to a smaller coolant line. I would say the hose is about 3/8 inch so pretty small. And yes it is a 2002 wrx.

 

Good call on the IAC valve. I just found a pic on a forum of the hose and this is the hose I am talking about. Thanks!!

 

Check it out... a part number!

 

This hose is tall dark and handsome. He loves long walks on the beach or just sitting around the fire with a glass of wine and a good book. He is a man about town, a staple in his local community. Volunteering at the local animal hospital is where he spends a lot of his extra time. He is looking for a soul mate someone to be his partner in life.

 

Unit 91, Sweet I must have skipped over the part # thanks! Meow quit calling me Radio Unit 91. Also I just realized you work at Stevens Creek Subaru so I'm that guy who just called. Art must have made me sound like an idiot haha. And I just called back and guess what Ken just called the part... A PRE-HEATER HOSE!!!! FML I wonder why Art didn't know what I was originally talking about.
