Default AC Question After Replacing Hose

So the low pressure suction AC hose has been leaking for a while and I am now getting around to replacing it and had a couple of questions.

I know this is a very common problem on our cars due to the bad crimps on the hose and I was wondering if the part I buy from Nissan would be an "updated" version of this part with better crimps or should I buy it from a specific place for a better hose.

Also when I do replace this hose, Would it be ok to just refil it using the can I can buy at O'Reilly or should I take it to an AC shop and have them properly evac and refill?

I would stick with the oem line. I replaced mine with the oem part and it has been just fine.

As for the refill, take it to a shop. That can is supposed to be for temporary fixes. Get your system properly recharged. And to replace the hose you need to have no pressure in your system so it would be beneficial to just let the shop do it all.

I agree with Nick. I believe AC work is something left for the pros...

Default Re: AC Question After Replacing Hose

I recently gone through changing the low pressure hose and here is what I did. I found a hose on ebay by a company called 4 seasons. I bought it for 78 bucks and free shipping. The Item name is : "Four Seasons 55121 Suction Line". Since I found out that the same problem persisted even with the 7th gen maximas and even altimas, I decided to go other than oem. I took the hose to a near shop and they asked for 150 bucks for changing, cleaning and lubricating the system for me. For now I'm happy and the ac works like a charm. I can't tell you whether this hose will go bad in 2 years or not and even if it does still I saved a couple of bucks there. It's given that oem hoses go bad, Such a disappointment from Nissan.

Default Re: AC Question After Replacing Hose

When I talked to Nissan about the hose they did say that they sell a new part but couldn't tell me if the crimp issue had been solved. After the wholesale discount it would be $125.

Firestone quoted me around $450 to do it all. If the AC machine is the only difference I think I might be able to borrow one from a friend that has a shop.

Altho I had my line leak but not from the ends,

your last statement I must agree as I had a Hydraulics crimp new ends to my power steering line which seems like a common issues, I talk to the owner and said the same thing you stated , which is common sense for the dealers to do that , spend the money on body and engine but cheap out on little parts so that we the owners must go back to them.

Sometimes having shops that can do this makes a difference having the exisiting part improved.

but some owners dont have the resources in their area for that.

to the OP I would stick with the OEM if you don't have shops local that can crimp the ends for you.

Default Re: AC Question After Replacing Hose

Hey guys i am having the upper ac hose leak problem on my 05 maxima . I have to recharge it with freon for the last three summer ever since i have the car i had to refill it with freon to have the ac working during the hot summer days where can i find a cheap autoparts store that sell this suction line hose for a cheap price .

I search online but the cheapest i can find it is for $ 100 dollars and i am not sure if the lower hose has to be replace as well but what i do know is that the upper one is leaking because the mechanic had put a dye on it and there is a green film on top of it i went back to get check out he said the upper hose is leaking . Should change the lower one too ?

Default Re: AC Question After Replacing Hose

When we say the low side AC hose, we are talking about the hose directly in front of the dipstick. If you've had to recharge your AC for 3 years in a row, I am absolutely shocked that your whole AC system hasn't taken a shit yet. By just recharging and not fixing the problem you are letting the problem get worse each time. The hole will just keep growing.

Replace the "low side" AC hose and then re-assess your situation.

Default Re: AC Question After Replacing Hose

Simply recharging the system is a band-aid. If you have to recharge your system, then there is a leak...the system is sealed. If you have a leak, you can/are getting moisture in the system...this will cause all kinds of headaches down the road and will lead to a HUGE expense to fix.

You also will not find this hose for cheap...go to the dealer and buy the hose...this is not something you want to have to fix again in another year.

Default Re: AC Question After Replacing Hose

I didn't realize I never updated this thread but I did buy the hose from the dealer for $125. Its normally around $150 but since I have a wholesale account is 20% less. I ended up replacing the hose myself (Took around 30 mins to do) then drove to a shop owned by a buddy of mine to recharge the system (I owe him lunch).

We had a temp gun to the vents while the AC was on full blast and it slowly dropped from 60 to 38 degrees!

For Targus: The hose that you say is leaking for sure, Is that the same hose you recharge through? Because that is the low side suction hose which I replaced and is a very common issue on our cars. I believe the high pressure hose is all metal and I doubt thats your issue. Here's a diagram if it helps. The red arrow points to the low side suction hose that I replaced.
