Hello new to this Chevy forum. i own an old 2000 1500 silverdao 4.8L 4x4 and was wondering if there is a Known weak spot on these trucks that the 134a leaks from.

Yea, i did manage to charge it and it cooled pretty good compressor was running very quietly but it leaked out a day later. Im gonna look at the eval coil?? are there any known ac leaks on these trucks that keep popping up you know of?

On a truck that old, it could be about anything, but finding the source is not unlike finding any other fluid leak. Look for areas that appear wet or have dirt/debris stuck on them. If it’s leaking fast enough to lose the charge in a day, it shouldn’t be too hard to see.
It may help to remove the grill and air box to get a clear view of the condenser and lines. If nothing else, get a UV dye charge to trace it - with large leaks, it’s easy to see the source without actually needing a UV light and glasses. |

With my 1998 Tahoe the evaporator developed leaks and to replace it the entire dash would have to be removed. Labor costs made this an unwise investment.

there with nothing to do during the hot months and so on, Evaporators going out are usually the result of moisture/air in the system. |
