Chassis AC running new lines

Post by Robert K »

Over the last 2 years I have changed everything in the system and still have a leak some where. We have blacklighted used sniffer and still not found a leak.
Has any one tried pulling new lines thru the frame or has any one run new lines some other way.
I doubt there is a leak in the line, but wonder if they spliced it for some reason.
Just something to think about

Fast leak or very slow leak?
Do you see any oil residue anywhere on the exterior of the system?

Slow leak . No have never seen oil.
We will probably run the lines temporary to see if it solves the problem and maybe make it permanent,if a good mounting sys is found.
I am thinking run it in 1"conduit for each line

I have a new steel brake line run from front to back, under the basement floor frame, soon to be replaced with stainless steel, (hopefully in a chassis frame rail).

Luckily my A/C hoses and coolant hoses are still good at 150k+ miles.

Robert,
When was the A/C last serviced (charged), and had there been previous leakdowns of the freon noticed? Was a dye added at the last charge?
How often have you used the A/C since last charged? Possibly you leak is at the compressor and from the seals that have been drying out from non-use?
