Hi

My g35 coupe 2004 have a ac leak somewhere. Is a good thing to change both the high and low at the same time. I was trying to look for a diy but didn't come up with anything. Is there anything i need to know before doing this job at home, any special tool i need to get? Thanks for your help!

p.s every few month i have to buy a freon ac can to make my ac cold again.

thank you

Yeah u need a special tool to get it out of the firewall..

 

there's a little plastic tool you can get for a couple of bucks to take out the ac line...have you tried a little stop leak sealant? fixed my leak after i had already purchased the line, wish i had tried it first. They have one that shows in a highlighter color to show you where the leaks are
