Another thing to wire up..

For leaks on a DSM, one spot that likes to leak on older cars, is the sides of the condenser (by the radiator) The condenser is made of aluminum with steel on the sides. The aluminum and steel over time start to form some electrolysis /corrosion and than start to eat the aluminum along the sides. The other spot that I see is sometimes on R12 systems, is the Schrader valve on the drivers side by the fender looses the o-ring under the cap. The molding of the cap has a nub that hit’s the valve when its on tight with out the o-ring.
