Hello all,
What precautions should one take before opening AC system on a Chrysler Intrepid 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 the system.
I need to have a couple of defective components replaced (compressor is OK), but I am concerned that if it is a moisture activated sealant, 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 they 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.
Thank you...
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.
