how do you replace thr ac lines on a 98?

 

clamps and/or bolts hold the lines together in big sections. they also have o-rings at the joints.

if your system is charged, you might want to extract/save the refrigerant. its a little expensive.
you can buy new lines from rockauto, autozone, dealer, etc.
if your system isn't working you might want to replace the accumulator/dryer thing. you might replace it anyway.
remove/replace.
recharge the system by pulling a vacuum, checking for leaks, adding oil and refrigerant. most people don't have a vacuum pump and have to visit an AC service shop for this.

is that what you were looking for?

yes and no. First thanks for the responce.
I know that there's o-rings. I should have been more clear. Do I need a special tool to remove the lines or do I just unclamp and pull them apart?

 

Quick disconnect fittings just make sure youve bled the lines first
