Thanks, tonite I will look at the old compressor to get the exact model. The replacement is a duplicate of the original. The system was almost empty when I bought the car and I do not know what the original problem entailed. I decided to go with new parts as I did not know the car. I live in Maryland and this year we have had very few days above 80F. June has averaged 75F average high for the month with much rain and high humidity.
