Hi, Went to a few local mechanics to do a cooling system test and none of them had the right attachment. Does anyone know where I can find the right attachment for this car similiar to the one listed in the below post? https://www.matthewsvolvosite.com/forums/viewtopic.php?f=1&t=45709&sid=a9...

If you have a pre 1999 s40, you need Vol-VCR and an appropriate cable.
