Hey guys I'm back with another post about helping me find out what part i need. I pulled my power steering pump out(wow) and found this hose that has been disconnected for who knows how long. Can someone tell me what it is? I swear I saw what it was online a few days ago when i was shopping for other parts but now i forget. Thanks!

 

That looks like a refrigerant hose for your Air Conditioning.

I assume that your Air Conditioning hasn't worked for a while.

 

It has not worked for at least 2 years! Luckily I don’t need it much in the PNW. Do you or anyone happen to know if it is a problem as is? Could I just pull that line out and plug that hole? Do I even need to plug the hole? Thank you so much for the reply!

 

Do you plan on fixing the A/C?

If so, sealing it up will keep any further debris from going into the A/C system. There are already some debris that would need to be cleaned out before fixing the A/C, but capping it off would reduce further damage.

If not, It probably doesn't matter at this point because moisture and debris have already gotten into the system, and the A/C compressor and hose are only needed if you want the Air Conditioner to work.

 

Hey! Sorry i disappeared.

I went ahead and got a new hose since i like all the buttons to work in my car. My next question is: Is there anything i should do before installing the new hose? Like oiling the connection point? It looks like to recharge the system i will run a pump along with the special pressure gauges to remove moisture, but will that remove debris too? Then add the refrigerant and i should be good?

EDIT: I guess the main question is how do i remove any debris that may have gotten in the system?

 

You may be biting off a little more than you planned. Here's everything I know about air conditioning: https://www.yotatech.com/forums/f116...-r134a-284801/

You'll absolutely need to run some sort of AC Flush through your system (as I mentioned, the warrantee on a replacement compressor is almost certainly void without that step). The vacuum pump won't remove it, and if there is any significant amount of debris it will ruin the pump anyway. At the moment, you don't know the condition of your compressor (hoses don't just disconnect themselves for no reason). If there is any debris in the compressor, I doubt you can just "flush" is out.

But the other components (evaporator, TXV, condensor, lines) are simpler and can probably be flushed. (you "always" replace the drier when you replace the refrigerant) Then you have to decide on the refrigerant. I think the only real choice is to convert to R134a, which will require new o-rings. That isn't a big deal; you really need to remove each component to flush it, and just use new o-rings on reassembly.

Even though I did the complete recharge in my garage, I think there are big advantages to going to a shop with a real RRR machine (Recover, Reclaim, Recharge).

Good luck!

 

Wow! Thank you for the write up. Part of me wants to do this while my power steering pump is out, but I just don't need A/C where I live. I'd rather just have my truck back on the road so I'm thinking I'll save this project for another time (or for a shop). Today I'll just install the new hose and make sure not to press my A/C button ever.
