Vette(s): My 1974 Vette sold last August 2014. I am still willing to show up to events and local gatherings if anything happening No new vette yet.
I am having my motor rebuilt this winter by my friend/mechanic. he will be pulling my motor out.
i know for a fact i have a leak in my AC line, currently there is no freon in the system and the belt has been off the compressor for a while. would it be easier and cheaper to replace the lines now while the motor is out? or would it not matter if i did it at a later date?  either way i want to replace my lines since everytime i go to get the work done on the system it is too cold to test it all since the outside temp. is colder than the air the AC would be pushing. 
 
Tips, answers, ideas would be great. i am sending my vette into the shop in 2 weeks as of last friday 11/3/06.
 
thanks,
Jeremy H.

It would be much easier to replace the line(s) with the engine out, tho they can be done with it in, also. The only reason it may be cheaper to do it while the engine is out would be due to it simply being easier, labor-wise.

Definitely do the lines while the engine is out of the car. I did mine with the engine in the car. It was difficult due to working in such a confined space. I did help to remove the hood first.

Much easier with motor out. The more room you have to work the better. Be real careful if your removing the lines on evaporator. Its a steel nut going to alum. threads. They can get pretty corroded. Make sure you turn the clutch by hand to make sure your compressor hasn't seized due to not turning for a while. Terry

Jeremy,

Everything is easier w/ the engine out. 
 
Consider replacing the drier bottle, it's probably shot by now especially if the system is open. 
 
Good luck,
 
Anthony

Hey Jeremy, I would consider having everything replaced while the motor is out. Usually if one part is shot the other parts are also. If not they are not to far from being shot. I had my entire heat and a/c system done with the motor in and it was really expensive because it took so long to remove and replace parts in such tight spaces. Gene
