A/C: freon additives and the slow leak
While surveying the local parts store I noticed A/C freon with additives
like lubricants and sealer. Now it just so happens that I'm buying a van from a fellow who told me he gets his system recharged annually because of a slow leak. And the mechanic said the exchanger is buried in the dash, meaning lots of work to replace it. Apparently, the leak is in there. I asked my mechanic if using freon with a sealer would work. He claims it will seal everything up, including the capillaries. Is that possible? Could it? Wouldn't the manufacturer have problems with this product if it always plugged up the A/C? Or is this a mechanic who wants to get more easy work? thanks |

The fact that AC sealers exist on the market is in no way an endorsement that they don't cause problems, there is no shortage of people stupid enough to purchase such magic potions. Please clarify the part about "a mechanic who wants to get more easy work," it seems to contradict the part where you say "the exchanger is buried in the dash, meaning lots of work to replace it. |

A/C: freon additives and the slow leak
No problem.
I know it sounds contradictory, but I've done automotive work and know that wrestling with a transmission or other major work is a lot more strenuous than replacing some wiring, or piping or brake work. So, I consider this an easier task, save cataloging all the part placements. I've heard Click and Clack discussing using oil supplements for worn gaskets and rings when it's cost prohibitive to crack the manifold. I wondered if a similar situation carried into A/C systems. |

So, I consider this an > easier > task, save cataloging all the part placements. Not really. Nothing is going to be more apparent to the customer than something amiss in their interior, a squeak, a rattle, god forbid a speck or smudge... Pulling a dash is awkward work, slightly cleaner than pulling a transmission, not many look forward to it. > I've heard Click and Clack discussing using oil supplements for worn gaskets > and rings when it's cost prohibitive to crack the manifold. I wondered if a > similar > situation carried into A/C systems. Click and Clack is comedy (if you like that sort of comedy), nothing they say should be taken as accurate or advice. |
