And since this is a relatively simple system, I would encourage you to replace the flexible lines. If they’re the originals they will be porous, and while the system might hold a charge for a while, it will eventually leak out over few months. New lines aren’t that expensive, you can get a local hose shop to make them up for you. They’ll use a barrier hose that will prevent refrigerant from leaking through the hose material at the molecular level. The original hoses did not have this feature.
I highly recommend the “alternative” refrigerants, as I’ve found them to work well in R12 systems myself and they’re easy to handle and you don’t have to worry about killing the planet if they leak out or the system gets discharged. New hoses are even more important with this stuff, as the different gasses would leak at a different rate, meaning your system could remain charged but the ratio of gasses has changed and it no longer cools efficiently. Not sure these guy’s stuff would work on the W116, but it’s worth looking into as far as brackets and Sanden conversions: https://klimakit.com/about/ -D > On Jul 18, 2019, at 1:35 PM, Meade Dillon via Mercedes > <mercedes@okiebenz.com> wrote: > > Yes, correct on the compressor.
