Default Hole in AC Line, Subaru charing too much

Hey guys,
I think Subaru is ripping me off on fixing my AC.
When I was putting another hose clamp on my FMIC I put a hole in the line 7341, it's circled in red in the picture below.
Subaruparts.com is only charging $122.84 for it (orginally 155 but that was crossed out and it said 122). The dealer charged me $194 and some change for it today. He also said the labor would be about $170. How hard would this hose be to replace myself and then just have the AC recharged? I think $360 for this sounds a little high.
Thanks,
Mike

Charged you as in you paid for it? That is very high! If there's a hole in it you don't have to worry about evacuating it, just replace the hose and have the a/c recharged. Might cost you 225 total.

I paid for it, but they had to order it.
Im going to call and cancel it and just tell them to recharge the system.
Does anyone happen to know the part number for those 12mm bolts that have a 7 on them? I have them everywhere and i need a few extra.

Thanks,
Mike

Bad advice.

You still need to evacuate thoroughly to get the moisture out.

There are three reasons to evacuate the system with a vacuum after it has been open.

1. The vacuum will suck out any water that got in while it was open. It doesn't take much moisture to screw up the newly repaired system.

2. The vacuum will suck out any remaining oil so they are starting with none when they recharge the system. It is important that the recharge include the proper ratio of refrigerant and oil and you need to start from zero to get it right.

3. They will test to be sure that the system will hold a vacuum, thus checking for leaks.

There is a pretty standard process for how to do this and it takes some time.
It's their time, equipment, and expertise that they're charging most of that money for.

You can trust me on this one. If you just replace the hose and put in a couple of cans of refrigerant from AutoZone, you will be buying a very expensive compressor (And some related parts) in the fairly near future.

So what you can do, if you trust your only wrenching, is change the hose yourself and then bring your car to a professional a/c shop. Let them recharge the system (which will include the vacuuming the system). You save the labour in putting the hose in. You will need professional equipment to do the recharging correctly.

Timex is correct. The system should be pumped-down ie evacuated with a vacuum pump and recharges with freon and a correct quanity of refregeante oil. In addition; depending on how long the system was open you maybe should replace the absorbor (not sure of the name) as it's job is to contain any new moisture that gets into the system. Ed

Timex, you are correct. I did'nt word that well. You explained it well.

Thanks

The main point was that he's not saving any money buying the part from the dealership, and they are not doing him any favors on the price to fix the thing.

Any decent a/c shop can do it correctly, dealerships like to give you that little extra kick in the rear though.

The oil won't boil in a vacuum like water does so it stays put.

The air dosen't condense like freon does so it won't cool as well.

If it was open to the air for very long you would want to replace the receiver dryer (dessicant)

Is the bill $250 parts and the rest labor? The corner garage might beat that if you installed the parts.

Oil is not removed when a vacuum is pulled. Water boils and is removed by vacuum pump at the very low pressures of the vacuum (more than 28" Hg should be applied). It helps to completely warm the car before pulling the vacuum (higher temps boil water easier, even a low pressure).

Proper charging requires a R134a manifold gauge set to pull the vacuum, switch to R134a, purge lines, and charge the system w/ correct amount (weight) of refrigerant. If you have noticed a loss of oil at the leak site, you should add perhaps 1-2 oz of replacement oil (probably PAG), but I'm new to Subaru's.

New drier is a good option, if the system has been open to air for any significant length of time. You can discharge, replace the hose, and immediately vacuum w/o problems IMO.

Why not take the hose to a local AC shop. Most shops can produce a duplicate hose to match your OEM hose. I would expect less than $50, but it's been a while since I've had to purchase an AC hose. Even if the end fittings are some specialty type, they can cut them off and splice onto new hoses.

good luck

I need to call SubaruParts tomorrow because it says 4-10 days and it is like 80 out and I want my AC. I may just pay for Subaru to do it all for the conveince of it...
Bad idea?

Like a lot of things, it's a tradeoff between money and time and "official" vs aftermarket repairs. Your choice.
