I have to replace this high side cooler line on our 2011 Nissan Versa as the other line going into the rad or compressor is rusted and leaking even though I tried a new rubber ring.

Here is the best example I can give you about this line I am talking about. I bought this genuine from Nissan...

When opening the hood, this part looks a little daunting, it goes from the front end to left side ( standing in front of the car ) all the way to the back behind the firewall. It has one screw in the front ( where my old line is rusted up ) and judging from the new line it simply plugs into the back of dash behind the firewall. II can barely see it under the car and can barely reach it under the hood.

Does anyone have any advise how to approach this? Like unscrew the front, follow the line and just pull out the line from the back of the firewall? The new line just makes it look like it just sticks right back in that hole. I saw a comment on youtube saying its spring loaded? either way how the heck can I even get close to it to see how things look like and work with it...


any advice appriciated, thanks

If I get a chance to look at mine I'll update this, but usually the high side line connects near the right side of the radiator to a block, that holds the inlet and outlet on the condenser lines. Maybe one bolt holding a plate to hold it in. The outlet from the condenser goes to the thermal expansion valve on the HVAC box, but the connection is usually on the engine side of the firewall, not usually in the car. Same idea there, a plate with a bolt holding the lines in the txv. They may be hard to see and recessed a little. Sometimes removing the cowl gives you tons of room to work in that area.

ok so I did this with success
Basically, a video online made me realize that I needed to remove the cowl. The cowl is basically what keep the wiper system assembly and holds a bit of the firewall between the engine and the front dash... best I can explain it.

edit: tutti57 was pretty bang on with his explanation

I took that apart in order to be able to get to the end of the high pressure hose. It was not spring loaded so all I needed to do was unscrew a type of bracket and the aluminum high pressure line came loose. The challenge is removing this line, making sure you can remember where it goes when you tetris in the new line on the left side of the engine.

Once the line is in and securely screwed in I charge the system with r134a. cool video to remember the procedure

I now have cold air!!

hope this helps!
