I would do it and here's why..... it's cheap...and your refrigerant is already gone...so it's not like you have to evacuate the system..

by the way..it's likely the o-rings on the expansion valve will go before the valve itself.. unless someone tried to put sealer in the system...

my .02.

experience--- i almost didn't buy my CE because of an ac problem. it was the o-rings on the valve... but by the time you replace the o-rings..you are doing the valve anyway.

good luck... what's the valve -- 35 dollars?
