You can't be successful flushing 100% of the time, but experience will tell you if the cleaning process was or was not a success before recharging the system. Every system poses it's own challenges related to which lines and components need to be removed to facilitate flushing. Expansion valves can be cleaned in place if the evaporator has large enough tubing, or for several hours of extra labor in the case of most smallish import cars, it can be removed and cleaned or replaced if too crapped-up.

I am the OP. I spent many hours looking for the expansion valve. I
could not find it in the engine compartment. I assumed it had to be inside the evaporator on the passenger side. Taking that apart is not an easy job, so I sealed it up and hoped that the flushing would have taken care of any blockage in the expansion vavle. |
