air conditioning pump
 

i went to change why refrigerant over to r134. found out the pump was frozen, bought another pump, on the new ac pump the label states that the pump has 3 oz of pag oil in it and the book calls for another oil when using r143. question is do i need to figure out how to get the pag oil out or are the two oils comparable. this is for a 1990 legend. 2nd, are 1st and 2nd gen. acura seats front and rear interchangeable. thanks
