Hey guys,

I want to recharge my air conditioner. Which line do i charge? i have an 2002 maxima 3.5 engine.

 

George must have family.

 

Low pressure

 

First you should see if you can find where the old refrigerant leaked out and repair that. Otherwise you could just be wasting your money. Then I would sugggest pulling the system under vacuum for about 30 mins and then see if the vacuum holds (you can hold it for 5 minutes with your gauges). Then fill the low pressure side. It is probably better to take it to a shop if you aren't familliar with the process though.

 

Where is the low pressure located? A picture would be helpful.

Thanks

 

No man LOW PSI. It's not a part

 

Wrong

 

You have two ports - low pressure and high pressure. Your low pressure port is on your low pressure line. It is the line that runs along the passenger side of your engine and has a little bracket bolting it to your passenger front strut tower. Right by the strut tower you should have a port with a little black cap on it (sometimes the cap will be blue if someone changed it - by typically it's black on these).
