What precautions should one take before opening AC system on a
vehicle (after it was evacuated) if there is a suspicion at at some
point in the past sealant was introduced into the system. It appears
that the previous owner of this vehicle had some sealant dumped into
I need to have a couple of defective components replaced (compressor
is OK), but I am concerned that if it is a moisture activated
the moment they open up the system it will harden and make the mess
out of the system...
I was advised by the shop that they will not be willing to flush a
system known to contain a sealant -- not sure why, they said that
have filters on their recovery equipment, but not on their flushing
equipment -- does not make much sense to me.
Any advice and/or experiences would be greatly appreciated.
P.S. The system will be deep vacuumed before and after the opening,
but I am concerned about the moisture that will inevitable enter when
they work on the system...
P.S. II I posted this message to the Chrysler group as well, just
wanted to get more opinions.
