Default AC high pressure hose interchange?

So I FINALLY found the leak in my A/C system. I need a new High Pressure hose from the compressor to the condenser. It's the one w/ the HP service port. Does this part interchange with any other years or models? Can I get one used or should I get a new one? Anyone know the PN? For 02 WRX. Also, how many o-rings do I need for all the connections in the engine bay and anyone know PN's for the rings? Thanks in advance.

So was it leaking at the junction under the foam boot?

If your system is totally depressurized, you can just unbolt the hose and pop the new one on yourself, then bring it somewhere to evacuate and recharge.

Call around to a few places that do AC work. Generally places will charge $80 bucks for the AC service plus freon. $35 to $40 a pound for freon.

Check out my post number 3 in this thread. I listed the part number. That's all you'll need to order. The hose comes with a new O ring on each side.

I ordered pretty late on a Thursday and Jamie got it right out that day. $7.95 shipping for USPS priority and it got to me in 2 days. FTW

Thanks. It was leaking from under that foam thing. I've got the vac pump and manifold so I can evac/charge properly. There's no 134 in the system so I won't have anything to recover, which is good b/c I don't have tools to recover

Do I NEED to get a new part, or can I use a used one from an 04 or something newer? I'd rather not spend $130 for a dammed hose, although, I'm just happy to be at the top of the hill finally.I've got like 7 cans of freon here.

I looked around at a couple of junkyards but they wanted $75 because the MSRP is $165.

There's a used one on ebay $95 +13 shipping.

http://cgi.ebay.com/ebaymotors/2002-...spagenameZWDVW


I was pretty sketched about buying a used one though because mine crapped out pretty quickly, I didn't want to spend the money to have my AC serviced and then have it be another crappy hose.

I was hoping if I bought a new one, maybe by now Subaru would have fixed the crappy press fit where they seem to leak.

BTW - I looked on SubaruGenuineParts and it says MSRP 165....your price 165, meaning the discount price doesn't seem to be calculating.

BUT Dan Perkins Subaru online has it for $129 also.

http://www.subarupartsforyou.com/cp_...hp?partid=7314


I also thought about trying to get it fixed at a hydraulic hose shop but didn't seem to be worth it.

^ BTW - torque spec for the 2 bolts that hold down the hose is 10.8 ftlb...don't overtighten and strip anything!

Ok, looks like from 02-06 impreza ALL trims has the same part. I'm gonna try for a used one from an 05, if that doesn't work I'll buy new.

^yup that's it...I thought even back to 2000 impreza used the same part but check on that. (probably wouldn't want to get one that old though)

Also cross reference that part number for other models, ie forester, I think other models may use the same part as well.

I know the Baja uses it also. I don't want anyhting older than 04/05 so it'll last a few years longer.

Yeah, mine was an 04 and it had the leak...it also had little pinholes on the rubber hose. That's why I was hesitant to buy any used one because if it was bad, not only would I be out the money for the hose, but also the $120 for the AC service.

I have this exact same problem on my 04 STi. Looks like Dan Perkins is the way to go for me. Dealership wants $399 but I can put the hose on no problem.

Can you rent the vacuum pump to clean out your system? The two bolts and filling the system is no problem so that's all I would need to pay someone to do.

A friend is telling me that since I still have R134a pressurized in my system that I can just release what pressure is left, unbolt the hose and cover the opening with saran wrap and quickly replace teh hose and the dryer in the ac system will take care of what little moisture is in the hose. Have any of you heard of this trick?

I didn't even replace the drier (although, it's probably not a bad idea) The new hose comes with a cap on each end to make sure crap doesn't get in there. I just popped the old hose off and put the new on immediately. I literally had no 134 left in there though. You can check by opening the blue cap on the high pressure port and pushing in the little pin.

I don't think you'll be able to rent an AC service machine (vac pump with the gauge manifold) Even at places that service AC, only 1 or 2 techs are able to do the service because they have to be certified.

No one will just charge you to fill the AC either. Everywhere I called wanted the $85 bucks or so for the "service" plus $35-$40 for the lb of 134a.

I've already got the manifold and vac pump, and the A/C hose came in last week. I got the PAG100 oil yesterday so I can stick the hose on today. I don't have an outlet outside though (apartment) so I gotta do it this week after work at a friend's house.

good deal...I was actually responding to ^Daytona's bump of your thread. He was inquiring about possibly being able to rent the equipment to evacuate the system.

I rented the vac pump and gauges from Autozone to do mine, about $400 for the deposit.

wow, your doin your own AC work ??

I'll swap engines all day, but when it comes to AC Just bring it to the shop...

My local place will troubleshoot your entire system, fix it , and charge with freon for $79.99. I think the freon to charge the system would be almost as much if I bought it myself...

Damm, that's cheap... Shops around here charge $200 for just a charge. I got 6 cans of 134a for $6 each, and the WRX takes about 2 cans.

Ya, it's like $7 after tax for the 12 oz cans of R134a at Wal-Mart so the shop is raping you. Awesome that I can rent that pump, just hook it up to the low pressure side and run it for an hour.

They sell R134a with the oil and compressor seal conditioner in the can, its actually cheaper than just the R134.

Zavigm: you did the hose urself and took it somewhere to have the vacuum service performed right? I don't think you need to be certified to use R134a right? That was just freon R12?

Found this, its a really simple how-to with the vacuum pump. No way am I ever taking my car into the shop for AC service! This is just too easy to do yourself, assuming this hose is the only leak you have.

yep, literally 2 bolts, 2 minute swap, then brought it to be evacuated and filled.

Now that I'm thinking about it, it's not the vacuum and fill that they need to be certified for, per se. It's more the recovery of the existing refrigerant that they want to make sure shops aren't discharging improperly. If you were to have to replace your compressor because of a bad bearing, the shop is supposed to recover the refrigerant into their machine, replace the component and then put the 134 back into the system.
