LB7: LB7 AC Line

[Vrabel]

Is there a different line that would fit an '01, or an aftermarket kit to route a different way? Just broke a second one in 5 yrs.

Where is it breaking?

The first time was my stupidity, I leaned on it and snapped it. Today. the liquid line right at compressor. Dont know how, but it cracked and blew open.

I had to have one made on the 04 for the low side but haven't had any trouble out of the liquid line yet--yet. Most hydraulic hose shops can build them and its usually close to the same price as a new one, sometimes less.

This is weird. As much stress as has been on mine (engine pulls, wrenching, etc), I haven't broken one in 7 years.

I know of a few other trucks that have had the motors pulled 6...7...8 times but kept the AC system intact.

Certainly not common.

Well, what actually happened was I was driving with my plow on up a hill at a steady rpm. Suddenly the temp gauge shot up so I hit the heat to max. Not realizing it was on defrost, when it gets so hot (over heating) the freon pressure goes way up and pop it went.
